Stepping up in the same colour and case shape
The PR 100 name dates to the early 1980s, the initials standing for Precise and Robust — a collection built around the idea that a sports-oriented everyday watch should not require much thought from the person wearing it. This green-dialled version updates that brief with a sunburst dial whose depth shifts noticeably as the light changes, paired with a fixed bezel that keeps the full dial visible rather than dividing attention. What makes the case unusually wearable is the lug-to-lug measurement, which matches the case width exactly at 40mm. That compact footprint, combined with an 8.25mm thickness, means the watch sits close and flat regardless of wrist size, and disappears under a cuff. The butterfly clasp is engraved with the brand name and opens with dual pushers, giving a cleaner line on the wrist than a folding buckle would. The bracelet runs on a quick-release system, so swapping to a different strap requires no tools. The quartz movement includes an end-of-life indicator — when the battery runs low, the seconds hand begins skipping in multi-second intervals rather than stopping without warning, which is a small but genuinely useful detail in daily wear.

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.
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.
