Tissot Seastar 2000 44mm Mens Watch Black
Ref. T1209071105100
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 310 Tissot watches in stock.The 2026 Seastar 2000 is the first meaningful rework of this line in some time, and the headline decision is restraint: Tissot pulled the case back from 46mm to 44mm and shaved the thickness from 16.25mm to 15.29mm, a small-looking change that makes a real difference in how the watch sits. The 46mm generation was a commitment; this one will clear a shirt cuff on most wrists and stop short of the overhang that made its predecessor awkward on anything under seven inches. The Powermatic 80 inside is the right movement for a watch used hard — 80 hours of reserve means three days off the wrist without resetting, and the Nivachron balance spring resists magnetism and temperature swings better than conventional hairsprings. The exhibition caseback is worth opening: the finishing is honest and the rotor carries its own weight. ISO 6425:2018 certified and fitted with a helium escape valve, it is built for saturation diving rather than pool swimming, which the ceramic unidirectional bezel and screw-down crown reflect. The power reserve indicator on the dial is a practical addition at this depth rating, not a decorative one.

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 600m 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?
22mm. 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.
Is it a men's or women's watch?
Listed as men's.
