Stepping up in the same dial colour
The PRX case shape dates to 1978, and the line has been revived and extended steadily since; this ice-blue dial variant arrived in 2023 as a colour addition to the permanent Powermatic 80 family. What makes the dial more than a palette swap is the Clous de Paris texture — the fine waffle-grid catches light at an angle in a way a plain sunray surface does not, giving the blue somewhere between warmth and depth depending on where you are standing. At 40mm wide and 10.93mm thick, this is a genuinely slim watch for what it is, and the integrated bracelet only adds to that — the case flows into the links without a visual break, so the whole thing reads as a single flat object on the wrist rather than a case sitting on top of a strap. The bracelet articulates well from new, no stiffness to work out of it, and at 138g the overall weight feels balanced rather than absent. The movement inside is an upgraded ETA 2824-2 base, running at 21,600 vph with a Nivachron antimagnetic hairspring — it is the anti-magnetic protection that earns the most in everyday wear, where proximity to phones and bags is unavoidable. The 80-hour reserve is visible through the exhibition caseback, and means a watch left on the nightstand Friday morning will still be running Monday.

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.
What size strap does it take?
12mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
