Tissot Seastar 1000 Powermatic 80 40mm Mens Watch Turquoise
Ref. T1208071109100
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 1000 has always been Tissot's case for the idea that a serious diver's specification need not cost serious money, and this 40mm edition with the Powermatic 80 sharpens that argument. Where the 43mm sibling can feel assertive on a narrower wrist, this version lands at 46mm lug-to-lug — compact for the category — and carries the same 300m rating and 80-hour power reserve in a case that simply gets on with the day. The graded turquoise-to-black dial does something that flat colour cannot: it changes character as the light moves, reading almost green at one angle and closer to teal at another, with the fumé finish giving it depth rather than flatness. The bracelet mirrors the dial's two-sided approach — brushed outer links, polished centre — and tapers cleanly through to the clasp, sitting flush rather than splaying at the wrist. The Powermatic 80 movement, visible through the screw-down caseback, is ETA's Nivachron-sprung calibre running at 21,600vph. The Nivachron balance spring is notably resistant to magnetic fields and temperature swings, which matters more than it sounds on a watch that will actually see water.

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.
Cheapest place to buy
Both Mappin & Webb and Goldsmiths list it at £685, so choose on delivery and warranty rather than price.
