Stepping up in the same colour and case shape
The PR 100 name has always stood for the same three things: precision, robustness, and a depth rating serious enough to mean something. This iteration keeps to that brief without fuss — 316L steel throughout, a narrow bezel that gives the blue dial more room than the case size alone would suggest, and an 8.25mm profile that stays close to the wrist and clears a cuff without difficulty. The quick-release bracelet swaps tool-free, which in practice means the watch adapts to a leather strap for evenings without any ceremony. The ETA F06.115 includes an end-of-life indicator, so the battery announces itself before it fails rather than after — a small thing, but the kind of detail that makes a daily-wear watch quietly easier to live with.

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.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
