Category-by-Category Analysis
Design & Aesthetics
Same idea, different details
Both are 40mm steel watches with integrated bracelets in the 1970s sports-luxury tradition. The PRX has a waffle-textured dial; the Tsuyosa has vibrant dial colours and a cyclops date magnifier. Pick the one whose dial you like.
Movement & Performance
80 hours against 40
The PRX runs the Swiss Powermatic 80.111, 23 jewels at 21,600 vph, with an 80-hour reserve. The Tsuyosa runs Citizen's calibre 8210, 21 jewels at 21,600 vph, with a 40-hour reserve. The PRX will still be running after a weekend off the wrist; the Tsuyosa will likely need resetting.
Durability & Water Resistance
100m against 50m
Both use sapphire crystals; the Tsuyosa adds a cyclops over the date. The PRX is rated to 100m (10 ATM) and the Tsuyosa to 50m (5 ATM). The PRX is the one to wear swimming.
Wearability & Fit
Both 40mm
Both are 40mm on integrated bracelets. On diameter they are the same; integrated bracelets can wear larger than the number suggests, so try both if you can.
Value & Cost of Ownership
The Tsuyosa is a band cheaper
The Tsuyosa sits in the $250–$500 band and the PRX in $500–$1,000. The PRX earns its premium with the reserve and water rating; the Tsuyosa gives you the look and sapphire for less.

Who Should Pick Which
Pick the Citizen Tsuyosa Automatic if…

Pick the Tissot PRX Powermatic 80 if…
- Strong value proposition under $1,000 with automatic Swiss movement
- Active lifestyle wearers — 100m water resistance handles swimming and water sports
- Weekend warriors — 80-hour power reserve means it survives two days off the wrist
- Those who prioritize scratch resistance — sapphire crystal
- Integrated-bracelet aesthetic fans wanting the Royal Oak look for 1/20th the price
Citizen Tsuyosa Automatic
- No hacking seconds. When you pull the crown to set the time, the seconds hand continues running. Setting precisely to-the-second is impossible. The single most-cited Tsuyosa complaint.
- Unidirectional rotor. Only winds in one direction; reserves take longer to build than bidirectional movements.
- Modest accuracy spec. ±10 to +25 sec/day in practice is the realistic band; significantly worse than the Tissot Powermatic 80.
- Proprietary endlinks. Limited strap-swap options.
Tissot PRX Powermatic 80
- Retail markup is generous. The PRX commonly transacts well under list on Jomashop, in Tissot's own online promotions, and at authorized online dealers. Paying full retail is rarely the right move, because the street price sits below it.
- 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.
Our Verdict
Citizen
Tsuyosa Automatic
Choose the Citizen Tsuyosa if you want the integrated-bracelet look for less money. It has a sapphire crystal, a cyclops over the date, and bright dial colours.

PRX Powermatic 80
Choose the Tissot PRX Powermatic 80 if you can stretch a band. It doubles the reserve to 80 hours, so it survives a weekend off the wrist, and doubles the water rating to 100m, which makes swimming fine.
Check Price on AmazonThe Bottom Line
The Citizen Tsuyosa and the Tissot PRX Powermatic 80 are both 40mm integrated-bracelet automatics with sapphire crystals, but the PRX has an 80-hour power reserve and 100m water resistance against the Tsuyosa's 40 hours and 50m, in a higher price band.
