Stepping up in the same colour and case shape
The PR 100 has been Tissot's workhorse sport-casual line since the early 1980s, the name standing for Precise and Robust, and this current generation sharpens the silhouette without abandoning what made it practical. The ETA F06.115 inside is the same Swiss quartz calibre Tissot fits to the PRX, and it carries an end-of-life battery indicator — a small but useful feature that means the watch will tell you when it needs attention rather than simply stopping. What makes the case geometry notable is the lug-to-lug measurement matching the dial width exactly at 40mm, so the watch sits entirely within its own footprint on the wrist. Combined with an 8.25mm profile, it disappears under a shirt cuff in a way that many watches rated to 100m do not manage. The sunburst blue dial reads differently in shade and in direct light, the baton indices keeping the face uncluttered. On the wrist the bracelet carries real weight at 122 grams, which gives it a presence the slim case alone would not suggest.

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.
