Tissot Seastar 1000 Powermatic 80 40mm Mens Watch Stainless Steel
Ref. T1208071105100
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 Seastar 1000 has been through a quiet but meaningful revision. The previous generation ran at 43mm, which put it at the larger end of wearable and sat heavily on moderate wrists. This new edition pulls the case back to 40mm and adds a notched edge along the case sides — a small change that sharpens the silhouette considerably. The grey-to-black graduated dial is particular to this reference within the five-model release; the others go blue, bi-colour or full black PVD. At 46mm lug-to-lug and 12.5mm thick, this sits in an unusual position for a 300m-rated watch: genuinely slim enough to disappear under a cuff, with slightly curved lugs that hug the wrist rather than bridge it. The bracelet tapers and releases on quick-release bars, which makes swapping straightforward. Inside, the Powermatic 80 — an ETA 2824 variant built with a Nivachron balance spring that resists magnetic interference — runs an 80-hour reserve, long enough that leaving it off over a weekend costs nothing on Monday morning.

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 300m it is rated for swimming, snorkelling and recreational 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 comparedHow 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.
What size strap does it take?
20mm. 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 46mm, which suits wrists from roughly 16cm (6¼ 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.
