Pick the Rado True Square Automatic if…
- Weekend warriors — 80-hour power reserve means it survives two days off the wrist
- Those who prioritize scratch resistance — sapphire crystal
- Dress watch seekers who want understated elegance
Tissot PRX Powermatic 80
- 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.
Rado True Square Automatic
- Ceramic brittleness — virtually scratchproof but can crack/shatter under hard impacts. WatchUSeek Rado threads document multiple owner reports of ceramic cracking from drops that would only scratch steel cases. Insurance is recommended.
- Square format polarising — distinctive and modernist, but not for buyers who want traditional round cases.
- 50m water resistance — dress watch only; not for swimming sports or hard activity.
- Proprietary endlinks — severely limits aftermarket strap options.
