Price range £265 to £2,740 across 269 Tissot watches in stock.

The 45.5mm stainless steel case sits 11.9mm thick, with a fixed bezel carrying a black aluminium tachymeter ring. Beneath sapphire crystal, the black dial arranges three chronograph sub-dials — measuring to 1/10th of a second, up to 60 seconds and 30 minutes — alongside a date display and a battery end-of-life indicator. Hands and index markers are treated with Super-LumiNova. The stainless steel bracelet closes with a folding clasp fitted with both a safety lock and diver extension. At 188g, the watch wears with noticeable solidity on the wrist. Water resistance is rated to 100 metres. The movement is an ETA G10.212 quartz calibre.

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.
