Stepping up in the same colour and case shape
The PR 100 name has carried a specific promise since the early 1980s: precise, robust, water-resistant to 100 metres. This modern reference updates the geometry of that long-running line — the bezel is narrowed to open up the white dial, the crown is more integrated into the case, and the end links now release without tools, so swapping to a leather or rubber strap takes seconds rather than a trip to a watchmaker. At 8.25mm thick, the watch sits surprisingly flat for something rated to 100m, and at 40mm with a 40mm lug-to-lug it will fit a wide range of wrists without overhanging. The two-tone treatment — brushed steel on the case body, yellow gold PVD on the bezel and alternate bracelet links — reads as a considered pairing rather than an afterthought, and the applied gold-tone indices on the white dial carry that through. The ETA F06.115 inside adds one quiet practical touch: when the battery runs low, the second hand begins skipping in four-second intervals, giving the owner clear notice before the watch stops.

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.
What size strap does it take?
20mm. 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.
Will it fit my wrist?
Lug-to-lug is 40mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
