Tissot Seastar 2000 44mm Mens Watch
Ref. T1209071728100
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 Seastar 2000 Professional had an image problem its specifications never deserved: at 46mm and 16.25mm thick, it was a demanding wear for most wrists. This 44mm version addresses that directly, trimming the diameter and shaving the case to 15.29mm while retaining the full ISO 6425-certified 600m rating and helium escape valve that make it a genuine saturation diving instrument rather than a notional one. Nothing was sacrificed for the smaller footprint. The case redesign goes beyond the dimensions. A new lug curvature presses the case closer to the wrist, a notched case edge tightens the profile visually, and sandblasting from the crown guard through to the lug ends gives the steel a workmanlike quality that reads as purposeful rather than simply utilitarian. The orange gradient dial is a strong choice here — it catches light differently as the angle shifts, and against the ceramic bezel it keeps the watch readable from a distance. At 130 grams on the rubber strap, it sits closer and more securely than the steel bracelet option would allow, which on a watch this purposeful is the right call. The Powermatic 80 runs at 21,600 vibrations per hour, a lower frequency than most automatic movements, and that is where the 80-hour reserve comes from — three days unworn without losing time, which for a watch that may see intermittent use between dives is a quietly practical advantage.

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.
