Tissot Gentleman Powermatic 80 Open Heart 40mm Mens Watch Grey
Ref. T1274071108100
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 £1,875 across 349 Tissot watches in stock.The Gentleman line reaches back to Tissot's 1960s dress watches, and the Open Heart sits within it as a quiet argument that a movement window need not announce itself. The aperture is placed with restraint — enough to reveal the oscillating balance and connect the watch to its mechanical origins, not so large that the grey rhodium dial loses its composure. At 40mm with a 48.6mm lug-to-lug span, it wears slightly fuller on the wrist than those numbers alone suggest, though the rounded bezel keeps the dial from reading as large. The curved horns follow the wrist naturally. Beneath the domed, anti-reflective sapphire, the applied faceted markers and pencil hands carry SuperLumiNova, which earns its place on a watch rated to 100m. The Powermatic 80.601 is an evolution of ETA's long-proven 2824 architecture, extended here to an 80-hour reserve and fitted with a Nivachron balance spring — a non-ferrous alloy that resists magnetic interference better than traditional steel. The movement is visible through both the dial aperture and the exhibition caseback, which gives the owner two ways to read the same piece of engineering.

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 explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes 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 comparedWhat size strap does it take?
21mm. 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 48.6mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
