Stepping up in the same dial colour
The PRX line began as a 1978 Tissot design — a slim integrated case that reads more like a luxury sports watch than the movement price would suggest — and this 2024 extension brings the format a gradient waffle dial that shifts between ice blue and something closer to white depending on the angle of the light. That interplay is not printed onto a flat surface; the texture of the dial does the work, catching and scattering light in a way that changes as the wrist moves. At 40mm with a 44mm lug-to-lug span and a measured thickness of around 10.8mm, this wears closer to the wrist than the case diameter alone implies. The integrated bracelet is angled at the lugs rather than falling straight, so it follows the curve of the wrist rather than bridging across it — a detail that matters more in person than in photographs. Beneath the exhibition caseback, the Powermatic 80 runs on a Nivachron hairspring, which resists both magnets and temperature swings without needing demagnetisation, and the 80-hour reserve means a watch set down on Friday is still running Monday morning.

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.
Will it fit my wrist?
Lug-to-lug is 44mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
