Premium

Sits in Tissot’s upper tier here — more premium than three quarters of the Tissot watches we list, which start at £245.

Price range £245 to £2,740 across 374 Tissot watches in stock.

The 40mm stainless steel case sits at 11.5mm thick, giving it a slim, dressy profile on the wrist. The silver dial is arranged around a distinctive open-heart cut-out positioned below 12 o'clock, exposing the Powermatic 80's balance wheel. Baton markers and luminous hands keep the layout legible, while the sapphire crystal carries an anti-reflective coating on its underside. A quick-release stainless steel bracelet fastens with a push-button butterfly clasp, and an exhibition caseback reveals the movement in full. Power reserve runs to 80 hours.

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.

Water resistance explained

Will the glass scratch?

Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.

Sapphire, mineral and acrylic compared

Does it need a battery?

No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.

Quartz, automatic and solar compared

How long does it run for when it's not worn?

About 80 hours fully wound — enough to sit off the wrist over a weekend and still be running.

Is it a men's or women's watch?

Listed as men's, though at 40mm it sits in the range that suits anyone.
