Stepping up in the same dial colour
The PR 100 has long occupied the practical middle ground of Tissot's catalogue — a sports watch that takes its rating seriously without asking the wrist to carry a diver's bulk. This 36mm chronograph version pulls that balance in a particular direction: the lug-to-lug distance is equal to the case diameter, which means there are effectively no extended lugs at all, and the watch sits flush against even a slender wrist with almost no overhang. The blue mother-of-pearl dial earns its place here by shifting throughout the day — flat overhead light reads it as a cool, even blue, while any angled source draws out the iridescence underneath. Three chronograph subdials sit within that surface without crowding it. The ETA G15.212 that drives them carries an end-of-life indicator, so the seconds hand signals when the battery needs attention rather than letting the watch quietly lose accuracy — a small detail that matters more than it sounds on a daily wearer. The butterfly clasp and the tool-free quick-release system mean the bracelet is genuinely easy to swap, which suits a dial that changes character enough to ask for alternatives.

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?
18mm. 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 36mm, 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 36mm it sits in the range that suits anyone.
