Tissot Seastar 1000 Powermatic 80 40mm Mens Watch Blue
Ref. T1208073704100
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 shrank from 43mm to 40mm when Tissot revised the family, and that single decision changed what the watch is for. The notched case edge is a detail, but the tighter diameter is the substance: a diver rated to 300 metres at 40mm with a 12.5mm case sits close enough to the wrist to disappear under a sleeve, which is not what most watches in this category manage. The blue-to-black gradient runs across a vertically striated dial, deepening toward the edges under the black PVD case and ceramic bezel — at an angle the whole thing reads darker than it does face-on. The plongeur hands and applied markers carry enough Super-LumiNova to be genuinely useful at depth, not merely decorative. The Powermatic 80.111 inside draws from an ETA 2824 lineage but runs on a Nivachron balance spring, which is non-magnetic and measurably more stable across temperature changes than traditional alloys. The 80-hour reserve is visible through the exhibition caseback, and at 21,600 vph the movement is no sprinter, but it is not trying to be one. This is a calibre built to keep running across a long weekend without attention, and it does.

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.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
