Stepping up in the same dial colour
The PRX shape first appeared in 1978, and when Tissot revived it in 2021 the decision was to do so properly: integrated bracelet, flush case transitions, the geometry intact. This black-dial automatic arrived as part of that revival, carrying the original proportions into a watch built around a movement the 1978 case never had. That movement is worth understanding. The Powermatic 80 is an ETA 2824 derivative running at 21,600vph with a Nivachron hairspring — an alloy that resists both magnetic interference and temperature variation more reliably than a standard steel spring. The practical result is 80 hours of power reserve and a movement visible through the caseback that is more robust in daily wear than its accessible positioning might suggest. At 10.9mm thick, the watch disappears under a cuff in a way that most 40mm automatics do not manage. The one thing to know before buying is the bracelet geometry. The first link does not articulate, which pushes the effective lug-to-lug past 51mm regardless of what the case-only measurement implies — it wears larger than it reads on paper, and the butterfly clasp has no micro-adjustment, only half-links for sizing. On the right wrist it is a non-issue; on a smaller one it is worth trying in person. The embossed texture on the black dial, barely visible straight-on and more apparent in raking light, is the detail that prevents the watch from reading as plain.

Learn more about Tissot
Charles-Félicien Tissot and his son Charles-Émile founded the company in Le Locle in 1853, assembling gold pocket watches and, unusually for the time, exporting aggressively — Russia became a major market within a decade.
Tissot's history is a sequence of firsts achieved through willingness to try materials and ideas the establishment considered unserious. The first mass-produced pocket watch with two time zones came in 1853. The first anti-magnetic wristwatch in 1930. The Astrolon of 1971 was the first watch with a movement made largely of injection-moulded plastic, and it worked. The RockWatch of 1985 used Alpine granite for the case, followed by watches in wood and mother-of-pearl.
The T-Touch of 1999 was the most significant: a tactile sapphire crystal allowing the wearer to access altimeter, barometer, compass, thermometer, and chronograph by touching the glass, years before touchscreens were commonplace.
Tissot merged with Omega in 1930 and both became founding members of what is now the Swatch Group. Its position in the group is volume and accessibility — Swiss mechanical and quartz watches at prices most people can reach, with the Powermatic 80 movement offering an eighty-hour reserve at entry level.
The company has held timekeeping roles across cycling, basketball, motorsport, and fencing.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 80 hours fully wound — enough to sit off the wrist over a weekend and still be running.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
