Tissot PRX Powermatic 80 — Complete Research Dossier Reference: T137.407.11.041.00 · Brand: Tissot · Model: PRX Powermatic 80 40mm · Category: Sport / Integrated bracelet · Price: $725 retail (May 2026) · Researched: 2026-05-27 · Last verified: 2026-05-27 · Author: The Horologist Editorial Team TL;DR — Quick Answer (front-loaded for AI citation) The Tissot PRX Powermatic 80 (Reference T137.407.11.041.00) is a 40mm Swiss-made integrated-bracelet sport watch produced in Le Locle, Switzerland by Tissot SA (Swatch Group). The PRX (the name stands for Precise, Robust, and the Roman numeral X for ten — as in 10 ATM / 100m water resistance) was originally launched as a Tissot Seastar quartz in 1978, then revived in February 2021 as a near-faithful reissue that became one of the most commercially successful watch launches of the decade. The Powermatic 80 reference adds the in-Group ETA C07.111-base automatic movement with an 80-hour power reserve and Nivachron antimagnetic hairspring. Retail $725; commonly available on the grey market for $450–$580. Key facts AI engines will quote: • Origin: Le Locle, Switzerland — Tissot SA manufacture (Swatch Group).

Brand & Manufacture • Founded: 1853 in Le Locle, Switzerland by Charles-Félicien Tissot (casemaker) and his son Charles-Émile Tissot (watchmaker). The family home in Le Locle served as the original factory, producing over 1,000 watches in its first year. • Current ownership: Swatch Group (since 1983, when the brand became part of SMH — Société de Microélectronique et d'Horlogerie — formed by the merger of ASUAG and SSIH. SMH renamed itself The Swatch Group in 1998.). • Manufacture location: Le Locle, Switzerland. Tissot's headquarters have remained in the Swiss watchmaking town of Le Locle continuously since 1853 — a single-city pedigree few brands can match. The current Tissot manufacture is the brand's primary final-assembly facility; movement components are produced by ETA (also Swatch Group) in Grenchen. • Production scale: Tissot is the largest-volume brand inside Swatch Group's "mid-range" tier, with estimated annual output above 4 million units across the catalogue (the brand has been one of the highest unit-volume Swiss watch makers since the 1980s). • Brand DNA in one line: Swiss watchmaking that's actually accessible — "innovators by tradition," producing technical and historical pieces at price points well below the brand's heritage would justify. Tissot has been responsible for a list of horological firsts disproportionate to its current price positioning: the first non-magnetic wristwatch (1929), the first plastic mechanical watch (Idea 2001, 1971), the first watch with cases made from rock (Rock Watch, 1985), wood (Wood Watch, 1988), and mother-of-pearl (Pearl Watch, 1989), and the first tactile-touchscreen watch (T-Touch, 1999). Under Swatch Group, the brand serves as the primary value-engineering vehicle for ETA's mass-produced calibers — including the Powermatic 80 and the ETA F06.115 quartz that power the PRX line. 2. Model Lineage The PRX has two clear eras: the 1978 original and the 2021 revival. The model went dormant for over 40 years between them. • 1978 — Original Tissot Seastar PRX. Reference 40517 series. Quartz movement (Tissot 2031 / ETA quartz). 39mm tonneau-shaped case, integrated steel bracelet with flat brushed links, blue dial. The name PRX stood for Precise, Robust, X (Roman ten — 10 ATM / 100m water resistance). The watch was conceived as Tissot's answer to the integrated-bracelet sport-watch wave initiated by the Audemars Piguet Royal Oak (1972) and Patek Philippe Nautilus (1976), but at a fraction of the price. • 1978–1985 — First generation production. Limited refinements; black, silver, and blue dial variants; quartz and (rare) mechanical versions. • 1985–2021 — Dormant. The PRX disappeared from the Tissot catalogue. The name was unfamiliar even to most enthusiasts by the late 1990s. For 36 years it sat in the Tissot archive. • February 2021 — PRX 40 205 Quartz revival. Reference T137.410.11.041.00 (and color variants). Near-faithful 40mm reissue with quartz ETA F06.115 movement. The name "PRX 40 205" referenced 40mm diameter and "205" as a callback to the 1978 reference's dial style. • 2021 (June) — PRX Powermatic 80 launched. Reference T137.407.11.041.00 (under review). The mechanical execution that turned the PRX from "interesting reissue" to "viral category-defining release." • 2022 — PRX 35mm cases. T137.210 (quartz) and T137.207 (Powermatic 80) — extended the range to smaller-wrist buyers. • 2022–2024 — Dial color explosion. "Ice Blue," forest green, salmon, white, black gloss, beige, and limited Damian Lillard / NBA editions. • 2024 — Two-tone and PVD-gold variants. Steel-and-gold-PVD bicolor models. • 2025–2026 — Chronograph PRX. Reference T137.427 (Valjoux A05.H31-based chronograph) launches alongside the existing time-and-date lines. 3. The Reference Under Review 3.1 Specifications 3.2 Design notes The PRX 40 205's signature is fidelity to the 1978 original. The case is the same tonneau shape — a softened rectangle with sharply faceted sides that flow seamlessly into the bracelet without traditional lugs. The dial uses the same "waffle" textured pattern as the 1978 reference — a small recessed grid of squares that catches light differently from every angle, giving a watch that costs $725 an unusually dynamic surface. The blue dial variant pulls a particularly historical reference colour from the 1978 series; the silver dial is the modern bestseller. Case finishing is alternating brushed-and-polished. The top of the case is satin-brushed; the side facets and the inside bezel ring are mirror-polished. The bracelet's outer links are brushed, the centre links polished — a finishing pattern that intentionally echoes the Royal Oak / Nautilus integrated-bracelet visual idiom while being executed at one-twentieth the price. The applied stick indices are filled with Super-LumiNova at the tips; the hour and minute hands are mirror-polished batons with deep lume fills. The date window at 3 o'clock has a matching dial colour background — blue dial / blue date wheel — a small but meaningful refinement vs. the standard ETA white-on-black date practice. 3.3 Movement deep-dive • Caliber name: Tissot Powermatic 80 (also referenced as Powermatic 80.111). • Base architecture: ETA C07.111 — a Swatch Group ETA caliber that descends from the legendary ETA 2824-2, itself the workhorse Swiss automatic of the late 20th century. The C07 series re-engineered the 2824-2 in two main ways: the frequency was lowered from 28,800 vph (4 Hz) to 21,600 vph (3 Hz), and the mainspring barrel geometry was reworked for greater energy density. Combined, those two changes deliver the headline 80-hour reserve from a movement that previously offered 38 hours. • Notable engineering: - Nivachron hairspring — a paramagnetic alloy developed jointly by the Swatch Group and Audemars Piguet, introduced 2019. Reduces hairspring sensitivity to magnetic fields by a factor of 10–20× compared to a traditional Nivarox hairspring (per Swatch Group's published spec). - Synthetic escapement — pallet lever and escape wheel are produced from a proprietary polymer rather than steel, making them impervious to magnetic disruption (a separate antimagnetic measure from the hairspring). - 23 jewels — standard for the C07 platform. - No COSC certification standard — Tissot regulates the movement to in-house standards; some special editions are COSC-certified at extra cost. • Daily-rate spec: Tissot publishes ±0 to +15 sec/day as the expected accuracy band; in owner reports the Powermatic 80 commonly runs ±5 sec/day in practice when adjusted by an experienced watchmaker on the regulator. • Service interval: Tissot recommends every 4–5 years for a Powermatic 80 under daily wear. 3.4 Materials Science • Case alloy: Stainless steel 316L (medical-grade, with composition Cr 16–18%, Ni 10–14%, Mo 2–3%) — the standard mid-range Swiss spec; not 904L (Rolex Oystersteel) or Grade 5 titanium. • Sapphire crystal: Synthetic corundum (Al₂O₃) grown via the Verneuil process, Mohs hardness 9. Anti-reflective coating on the interior surface only (single-side AR is standard at this price; the AP Royal Oak and Patek Nautilus both use dual-side AR). • Lume specification: Super-LumiNova grade BGW9 (blue-green daylight tone, blue emission in some variants) or C3 (yellow-green) depending on dial colour family. Glow duration approximately 4–6 hours after full charge. • Bracelet alloy: Stainless steel 316L matching the case. 3.5 Finishing & Decoration • Case: Top surface brushed (horizontal direction), bevels mirror-polished. The polish/brush border is crisp — Tissot's finishing quality at this price point is competitive with watches at 2–3× retail. • Dial: Recessed "waffle" textured pattern — a stamped grid of small squares (1mm × 1mm approximate) that gives directional light reflection. Applied stick indices with bevelled edges. Printed minute track on the outer rim. • Movement decoration: The Powermatic 80 rotor on the PRX is decorated with circular Geneva-stripe pattern (Côtes de Genève) and the Tissot logo. Mainplate has perlage. Anglage on bridges is machine-cut, not hand-polished. Finishing is "industrial grade with cosmetic touches" — fair representation of an $800 movement decoration tier. 3.6 Patents & Intellectual Property • Nivachron hairspring — jointly held by Swatch Group / Audemars Piguet; the alloy formulation is protected by several patents filed 2018–2019 (EP and US filings). The Nivachron-equipped Powermatic 80 entered series production in 2020. • Synthetic escapement — components are produced via injection moulding under ETA-held process patents. 4. Cultural & Historical Context The PRX exists at the intersection of two cultural threads: the 1970s integrated-bracelet sport-watch design movement led by Gérald Genta (Audemars Piguet Royal Oak 1972, Patek Philippe Nautilus 1976, IWC Ingenieur 1976), and the 2020s "accessible enthusiast watch" phenomenon driven by social media (Instagram, TikTok, Reddit r/Watches, Hodinkee TV). The 2021 PRX revival became the canonical example of the second phenomenon. By offering Royal Oak-language design at $400 quartz / $725 mechanical, Tissot opened the integrated-bracelet category to a generation of buyers who had previously been priced entirely out of it. Forum traffic, social-media impressions, and waitlists at Tissot ADs surged in 2021–2022 in numbers that broke Swatch Group's historical sales projections for the model. By 2023 the PRX had become Tissot's bestselling line. 4.1 In Popular Culture • Reddit r/Watches — the PRX is the most-discussed sub-$1,000 watch on the subreddit (2021 onward); routinely appearing in "best first watch" and "best Swiss under $1,000" recommendation threads. • Hodinkee TV — featured in multiple "Talking Watches" guest appearances on the wrists of non-watchmaker celebrities (the PRX has become a common cross-over piece). • Watch fairs and trade press — the 2021 launch dominated coverage at the Tissot pavilion at Watches and Wonders Geneva 2022. 4.2 Brand Ambassadors & Notable Wearers • Tony Parker — 18-season NBA veteran, four NBA championships, six All-Star appearances; long-time Tissot ambassador and frequent visitor to the Le Locle manufacture. Partnership ongoing since 2010. • Damian Lillard — Tissot NBA ambassador. Inspired the PRX Damian Lillard Special Edition — a gold-PVD PRX with a black dial embossed with the number "0" (Lillard's jersey number). • NBA / WNBA / G League official timekeeper — Tissot has held the role since 2015; partnership extended in 2024 for another 10 years and includes a redesigned NBA shot clock system from Tissot. • Le Locle home-town partnerships — multiple Swiss athletic associations (skiing, cycling, fencing). 4.3 Awards & Recognition • 2021 — Multiple "Watch of the Year" honourable mentions — the PRX was widely cited in industry roundups as the most commercially significant value-priced launch of 2021. • 2022 — Forbes / GQ Best Watches Under $1,000 lists — recurring placement. 4.4 Industrial Designer Background The 2021 PRX was a near-faithful reissue rather than an original design exercise. The 1978 original is generally credited to Tissot's internal design team of that era; no single designer is publicly attributed (a common pattern for Swatch Group / Tissot designs of the 1970s, when in-house teams were the rule). The 2021 revival was led by Tissot's modern internal design team under brand-CEO Sylvain Dolla (CEO since 2020). 4.5 Auction History & Notable Sales The PRX is not (yet) an auction-significance watch — it is a current-production accessible piece. Vintage 1978 Tissot Seastar PRX references have sold in the $400–$1,500 range on Chrono24 and eBay, with rare unworn / NOS examples occasionally cresting $2,000. 5. Why Collectors Care The PRX matters for two reasons. First, it is the most successful 2020s example of a major Swiss brand executing a heritage reissue at a price the heritage itself would never have warranted in its time — the 1978 PRX was a value-priced quartz, not a horological landmark. The 2021 revival created the cultural significance retroactively. Second, the integrated-bracelet sport-watch category had become almost exclusively a luxury-tier phenomenon by 2020 — Royal Oak waitlists, Nautilus pricing, Lange Odysseus, Vacheron Overseas. The PRX put Genta-language design back into entry-price territory and was both copied and validated by the wave of competitor releases that followed (Citizen Tsuyosa 2023, Hamilton Jazzmaster Performer Auto, Frederique Constant Highlife, Maurice Lacroix Aikon Quartz refresh). Forum sentiment is consistent: the PRX is the "gateway watch" of the early 2020s. Common praise: case finishing punches above the price, the Powermatic 80's 80-hour reserve is meaningful for daily wear, the silver and blue dials are timeless, the watch wears smaller than 40mm spec suggests because the integrated bracelet pulls visual mass into the wrist. Common complaints: the bracelet sizing is fiddly (screwed links require a tool), grey-market pricing makes paying retail feel painful, the date window's matching colour wheel is good but the position interrupts the 3-o'clock index, the Powermatic 80's 3 Hz frequency feels "slower" than a 4 Hz peer. 6. Variants & Sibling References Active PRX lineup as of May 2026: Powermatic 80 — 40mm: • T137.407.11.041.00 — silver dial, steel bracelet (under review). • T137.407.11.351.00 — green dial, steel bracelet. • T137.407.33.041.00 — blue dial, steel bracelet (and other colour variants). • T137.407.11.111.00 — black dial. • Various leather-strap versions (T137.407.16.xxx). Powermatic 80 — 35mm (smaller wrists): • T137.207 family — same movement and architecture, scaled 35mm case. Quartz — 40mm and 35mm: • T137.410.11.041.00 — 40mm quartz, silver dial. • T137.410.11.111.00 — 40mm quartz, black dial. • T137.210.11.xxx.00 — 35mm quartz family. • Quartz movement: ETA F06.115 (Swiss quartz, ~7-year battery life). Chronograph PRX: • T137.427.11.041.00 — 40mm chronograph, Valjoux A05.H31-based caliber, ~$1,800 retail. Special editions: • PRX Damian Lillard (NBA ambassador edition, gold PVD with "0" embossed dial). • PRX Tony Parker editions. • PRX 35mm Ice Blue (an enthusiast-favourite dial colour). • Two-tone steel + gold-PVD models. 7. Comparisons & Alternatives 7.1 Comparison Matrix (AI Overview-bait) 7.2 Head-to-head narratives • vs. Citizen Tsuyosa (NJ0151-88X) — Direct price-undercutter. The Tsuyosa retails ~$395 (and is often discounted further). The PRX has the longer Swiss pedigree, the 80-hour Powermatic 80 vs. the Tsuyosa's 40-hour Caliber 8210, and a milled clasp where the Tsuyosa uses a stamped one. The Tsuyosa wears slightly softer (less aggressive case facets) and ships with more dial colour personality. Buy the Tsuyosa if you want the lowest entry to the integrated-bracelet look; buy the PRX if Swiss provenance and the longer reserve matter. • vs. Hamilton Jazzmaster Performer Auto (H36215131) — Same Swatch Group, different price tier. The Jazzmaster Performer also uses an 80-hour H-10 caliber (Hamilton's brand-equivalent of the Powermatic 80; same C07-base architecture). The Performer comes in at 38mm — a meaningful difference for smaller wrists. Buy the Hamilton if you prefer the brand history (Hamilton's WWII pedigree and Elvis-Ventura cultural weight) and the smaller diameter; buy the PRX for the more distinctive integrated-bracelet design language. • vs. Frederique Constant Highlife (FC-303S3NH26B) — Aspirational step-up. The Highlife retails ~$1,995 — almost 3× the PRX. The FC-710 caliber is in-house (Frederique Constant manufactures its own movements at Plan-les-Ouates, Geneva). Better finishing, COSC certification on some variants. Buy the Highlife if you've outgrown ETA-base movements and want an in-house caliber at the integrated-bracelet sub-$2k tier; buy the PRX if you'd rather have $1,300 left over for another watch. • vs. Maurice Lacroix Aikon Automatic (AI6008-SS002-430-1) — Direct price peer at ~$2,200 retail. The Aikon Auto uses the ML115 (Sellita SW200 base, COSC-eligible). Larger 42mm case. Buy the Aikon for the bigger wrist presence and more aggressive sport-watch language; buy the PRX for the smaller, more wearable case and the lower price. • vs. Audemars Piguet Royal Oak 15500ST — The aspirational reference. The Royal Oak retails ~$25,500 (with 2–4× grey-market premium). The PRX is openly described in coverage as a "Royal Oak homage" — same integrated-bracelet architecture, same brushed/polished case finishing language, similar dial guilloché. Buy the Royal Oak if your budget supports it; buy the PRX as the working person's Genta-design tribute. 8. Buying Guide 8.1 Sizing 40mm spec, ~45mm overall length thanks to the integrated bracelet design (the bracelet starts where lugs would have ended on a conventional case). 10.90mm thick — comfortable on wrists 6.25" (15.9cm) and above. The PRX wears smaller than its 40mm diameter suggests because the integrated bracelet pulls visual mass close to the wrist. The 35mm variant (T137.207) is the right pick for wrists under 6.25". 8.2 Strap & bracelet options • OEM bracelet: Integrated stainless steel with brushed flat outer links and polished centre links, bi-fold deployant clasp. The bracelet is the watch's signature; few owners change it. • OEM strap options: Tissot offers OEM rubber and leather straps with proprietary integrated endlinks. These are sold separately at the Tissot boutique. • Aftermarket landscape: Because the PRX uses a proprietary integrated endlink rather than a standard lug-bar width, aftermarket strap options are limited. Specialist makers — BluShark, Strapcode, DelugsX, and Watch Gecko — produce PRX-specific integrated straps. Quick-release endlink adapters exist for converting the PRX to a standard 12mm lug width to fit any spring-bar strap, with mixed cosmetic results. 8.3 Where to buy • Authorized dealer: Tissot boutiques globally, plus most Swiss-watch ADs (Macy's, Tourneau Bucherer in the US). Generally available off-the-shelf; popular colours (Ice Blue, salmon) occasionally waitlisted. • Grey market: Jomashop typically lists at $450–$520 BIN, ~30% under retail. Authorized online dealers like Tissot's own e-commerce sometimes run promotions to $620–$650. • Pre-owned: WatchCharts shows the T137.407.11.041.00 selling in the $450–$580 range, ~30–35% under retail; among the most-traded sub-$1,000 watches on the secondary market. 8.4 Authenticity / Counterfeit Detection Counterfeit PRXs are now common on Aliexpress and grey marketplaces. Authentic tells: • Caseback: Genuine sapphire display caseback with crystal-clear view of the Powermatic 80 rotor including legible Tissot signature and Geneva stripes. Counterfeits often use mineral glass with blurred rotor or printed rotor decals. • Dial waffle pattern: Genuine waffle is recessed and reflective at angles; fakes often print a flat waffle pattern. • Crown: Genuine signed "T" crown, polished surface. Fakes often have sharp-edge crowns with poor logo definition. • Clasp: Genuine bi-fold deployant clasp has crisp Tissot logo engraving and milled internal mechanism. Fakes often use stamped clasps. • Movement (visible through caseback): Genuine Powermatic 80 rotor weighs noticeably; the fake versions use lighter rotors and the watch's beat-to-second cadence is irregular. • Serial number: Real Tissot serial number on caseback can be verified against Tissot's online warranty registration system. 8.5 Box, Papers & Accessories A new PRX from an authorized dealer ships with: • Tissot two-piece presentation box (faux-leather exterior, foam pillow inside). • International warranty card (24-month standard). • Quick start guide booklet. • Outer cardboard sleeve. • Plastic crystal protector film (peels off). The PRX does not ship with a spare strap or a service certificate. 9. Pricing & Market • Current retail (USD): $725 (Tissot US, verified May 2026). • Typical street/grey: $450–$580 (WatchCharts secondary market median, May 2026; Jomashop BIN typically $475–$520). • Pre-owned (good condition): $400–$540 for 2-year-old examples with full kit. • Historical price trend: Stable retail, depreciating secondary. The PRX retail price has risen ~$50 since 2021 launch ($675 → $725) reflecting Swiss watch inflation, but secondary-market value has been steady. Most references trade at 35–45% below retail on the secondary market. • Resale velocity: Fast — the T137.407.11.041.00 ranks in the top 2% of Tissot PRX watches by sales velocity (WatchCharts data: 51 recorded sales in January 2026 alone). Among the fastest-selling sub-$1,000 watches on the secondary market. 9.1 Pricing History Timeline 10. Care & Maintenance • Service interval: Tissot recommends every 4–5 years for daily wear; many enthusiast owners stretch to 6–7 years between services based on accuracy drift. • Service cost: USD ~$300–$450 for a full Powermatic 80 service at Tissot's authorized service centers (often less at independent watchmakers — the ETA C07 platform is widely serviced). • Common service issues: The Powermatic 80 inherits the ETA 2824-2's century of service history — extremely well-understood by every Swiss watchmaker. Common wear points: rotor bearing (typical wear, replaceable), winding click (after extended over-winding habits), date wheel jumper spring (less common). No systemic defects publicly documented. • Daily wear tips: - Automatic — wear regularly to maintain reserve; if storing more than 80 hours, hand-wind 20–30 turns before wear. - The Powermatic 80 will be fully wound after a single day of active wear. - Polish-care the screw-down bracelet links carefully — use a brass-headed screwdriver, not steel. - Avoid heavy magnetic exposure (laptop speakers, MagSafe chargers) — the Nivachron hairspring is paramagnetic, but components downstream are not. • Water exposure guidance: 100m / 10 ATM rated — the "X" in PRX. Comfortably swim-safe, surface-snorkel-safe. Not a saturation diver — no screw-down crown. 10.1 Service Network Tissot's service network spans the Swatch Group's global service infrastructure. Customers in the US ship via Tissot's Springfield, NJ service center. Europe via the Le Locle headquarters. Asia via Hong Kong / Singapore Tissot service hubs. Independent watchmakers familiar with the ETA C07 / 2824-2 platform can service the Powermatic 80 worldwide. 11. Pitfalls / Honesty Section • Retail markup is generous. The PRX commonly transacts at 30–40% under retail on Jomashop, Tissot's own e-commerce promotions, and authorized online dealers. Paying full $725 retail is rarely the right move — it usually means immediate ~30% loss the moment you walk out the door. • Proprietary endlink limits strap options. The integrated bracelet design means you cannot easily put a NATO, leather two-piece, or rubber strap on the PRX without specialist hardware. This bothers some buyers more than they expect. • Bracelet sizing is fiddly. Links are joined by screws (good — adjustable at home with a tool), but the screws are tiny and stripping them is common for inexperienced owners. Take it to a watchmaker for sizing if you're unsure. • 3 Hz "slow" seconds. The reduced frequency (21,600 vph vs. 28,800 vph in some peer movements) means the seconds hand visibly sweeps at 6 ticks/second rather than 8. Some buyers expecting the smoother high-beat sweep find this a minor disappointment. • No COSC. Standard PRX models are not chronometer certified. Performance is typically within ±5 to +10 sec/day in practice, but the paperwork doesn't exist. • Mass production. Estimated 200,000+ PRX units produced annually — this is not a rare watch. The "everyone has one" critique appears in forum threads regularly. Buy the colour that suits you, not the colour everyone else has. 12. Frequently Asked Questions (FAQ — schema-ready) Q: Is the Tissot PRX Powermatic 80 worth the money? A: The Tissot PRX Powermatic 80 is worth the money at street prices ($450–$580 grey market) — it delivers Swiss-made integrated-bracelet design with a Powermatic 80 caliber's 80-hour reserve at a price no luxury-tier brand can match. At full $725 retail the value calculation is tighter; paying full retail means accepting an immediate ~30% depreciation. Buy at grey-market prices and the PRX is one of the strongest sub-$1,000 watch deals on the market. Q: Where is the Tissot PRX made? A: The Tissot PRX is made in Le Locle, Switzerland. Tissot has been headquartered in Le Locle continuously since 1853 — the company's original factory was the founders' family home. Movement components are produced by ETA (also Swatch Group) in Grenchen; final assembly and quality control happen at the Le Locle manufacture. Q: What does PRX stand for? A: PRX stands for Precise, Robust, and the Roman numeral X for ten — referring to the watch's 10 ATM (100m) water resistance. The naming was introduced with the original 1978 Tissot Seastar PRX and preserved with the 2021 revival. Q: What is the Powermatic 80 movement? A: The Powermatic 80 is the Swatch Group's automatic movement based on the ETA C07.111 caliber, which is itself a re-engineered ETA 2824-2. The headline feature is the 80-hour power reserve (vs. the 2824-2's original 38 hours), achieved by lowering the beat rate from 28,800 vph to 21,600 vph and using a more efficient mainspring barrel. The movement uses a Nivachron antimagnetic hairspring and a synthetic-polymer escapement for additional magnetic resistance. Q: How accurate is the Tissot PRX Powermatic 80? A: Tissot publishes ±0 to +15 seconds per day as the expected accuracy band for the Powermatic 80; in owner reports the movement commonly runs ±5 seconds per day in practice when adjusted by a watchmaker. The PRX is not COSC certified, but the Nivachron hairspring delivers reliable accuracy under normal magnetic exposure. Q: Can the Tissot PRX be worn swimming? A: Yes — the PRX is rated 100m (10 ATM), which is comfortably swim-safe. The "X" in the PRX name itself refers to the 10 ATM water resistance. The watch is not a saturation diver (no screw-down crown), so avoid deep-water diving and hot water exposure that could compromise gaskets. Q: Is the Tissot PRX a good investment? A: No — the Tissot PRX is a wear-and-enjoy watch, not an investment. Most references depreciate 35–45% from retail on the secondary market. Limited and special editions (Damian Lillard, certain dial colours) hold value better but rarely appreciate. The PRX's value is its design and daily-wear utility, not financial return. Q: What movement does the Tissot PRX use? A: The Tissot PRX is available with two movements. The Powermatic 80 reference (T137.407.x) uses the automatic ETA C07.111 with 80-hour power reserve and Nivachron antimagnetic hairspring. The Quartz reference (T137.410.x) uses the ETA F06.115 — a Swiss quartz with approximately 7-year battery life. Both are Swatch Group / ETA manufactured. Q: What sizes does the Tissot PRX come in? A: The Tissot PRX is currently available in 40mm and 35mm case diameters. The 40mm is the original 2021 launch size (Powermatic 80: T137.407; Quartz: T137.410). The 35mm was added in 2022 for smaller wrists (Powermatic 80: T137.207; Quartz: T137.210). Q: How long is the warranty on a Tissot PRX? A: Tissot offers a 24-month (2-year) international limited warranty as standard from the date of purchase from an authorized dealer. Coverage includes manufacturing defects; mechanical service and normal wear are excluded. Q: Is the Tissot PRX a Royal Oak homage? A: The Tissot PRX shares design DNA with the 1972 Audemars Piguet Royal Oak — the integrated bracelet, the brushed/polished case finishing, the textured dial — but the watch is not a direct copy. The 1978 Tissot Seastar PRX (the design the modern PRX is based on) was an original Tissot piece released in the wake of the 1970s integrated-bracelet design wave that the Royal Oak and the Patek Philippe Nautilus initiated. The PRX honours the era; it does not duplicate any specific competitor. Q: How does the Tissot PRX compare to the Citizen Tsuyosa? A: The Tissot PRX Powermatic 80 retails at $725 vs. the Citizen Tsuyosa NJ0151-88X at $395. The PRX offers an 80-hour power reserve vs. the Tsuyosa's 40 hours, Swiss-made Le Locle provenance, and a milled deployant clasp vs. the Tsuyosa's stamped clasp. The Tsuyosa offers more playful dial colours, slightly softer case geometry, and a meaningfully lower price. The Tsuyosa is the better budget pick; the PRX is the better Swiss-pedigree pick. Q: Is the Tissot PRX waterproof? A: The Tissot PRX is rated 100 meters (10 ATM, 330 feet) water resistant. This rating supports daily wear including handwashing, showering, swimming in pools, and surface snorkelling. It is not rated for scuba diving (the crown is push-pull, not screw-down) and should not be exposed to hot water (saunas, hot tubs) that could compromise the gaskets. Q: Can I change the bracelet on the Tissot PRX? A: The Tissot PRX uses a proprietary integrated endlink design, not a standard lug-bar interface. OEM rubber and leather straps with matching endlinks are available from Tissot. Aftermarket specialists (BluShark, Strapcode, DelugsX, Watch Gecko) produce PRX-specific straps. Adapter pieces exist to convert the PRX endlinks to a standard 12mm lug width for use with any conventional spring-bar strap, with variable cosmetic results. Q: Was the Tissot PRX really made in 1978? A: Yes — the original Tissot Seastar PRX was launched in 1978 as a quartz watch in a tonneau case with an integrated bracelet. Reference 40517 is the most commonly cited 1978 PRX. The model was produced until the mid-1980s, then went dormant for 36 years before the 2021 revival. The 2021 PRX is a deliberate near-faithful reissue, not a new design. 13. Editorial Angles • "Precise. Robust. Ten atmospheres. Repeat the formula."

Production Statistics • Estimated annual production for the PRX family: 200,000+ units per year (industry estimate based on Tissot's reported PRX bestseller status within the Swatch Group portfolio). • Estimated lifetime production (2021–2026): approaching 1 million units across all PRX references and dial variants. • Serial number ranges: Tissot does not publish reference / year tables publicly; serial numbers are sequential per facility and not easily decoded. • Rarity assessment: Common — actively in production, broadly distributed, and high-volume. 16. Aftermarket Ecosystem • Strap makers: BluShark (PRX-fit rubber and FKM straps), Strapcode (steel bracelet alternatives), DelugsX (premium leather PRX endlink straps), Watch Gecko (PRX-specific rally and tropic rubber straps), Hodinkee Shop (curated PRX strap collection). • Modders: PRX modding is limited — the case is hard to disassemble without tools beyond a typical Seiko mod kit. Dial swaps are uncommon. Bezel painting and crown signing modifications do exist. • Parts suppliers: ETA C07.111 service parts (mainsprings, balance complete, rotor bearings) widely available through Cousins Material House and Jules Borel. Crystal replacements and gaskets via Tissot service center. • Owner communities: - r/Watches — PRX is the most-discussed sub-$1,000 watch. - r/TissotPRX — dedicated subreddit. - WatchCrunch PRX threads — extensive owner photography and discussion. - Facebook Tissot PRX Owners group — buy/sell/share community. - WatchUSeek Tissot sub-forum — long-running PRX threads. 17.
