Our take on the Tissot Seastar 1000 Powermatic 80 Turquoise Dial Automatic Diver's T120.807.11.091.00 300M Men's Watch

The Seastar 1000 Powermatic 80 is Tissot's entry-level automatic dive watch, rated to 300 m with a screw-down crown, sapphire crystal and a unidirectional rotating bezel. This version pairs a 40 mm steel case with a turquoise-to-black gradient dial and the Powermatic 80 movement, which runs about 80 hours on a full wind. It sits below Swiss rivals like the Longines HydroConquest and Tudor Black Bay on finishing, but undercuts most of them on movement specs. Owners like the slim 12.5 mm case and the long reserve; the bracelet clasp and bezel action draw the most complaints.

What reviewers say

Reviewers treat the Seastar 1000 Powermatic 80 as strong value in a Swiss automatic diver. The dial, case size and power reserve get consistent praise; the bracelet and bezel are the usual letdowns.

What people mention

  • Power reservePraisedThe roughly 80-hour reserve lets it sit a weekend or more without stopping.
  • BraceletCriticisedReviewers find the bracelet heavy and the clasp below the level of the watch.
  • BezelMixedThe rotating bezel works but some owners describe the action as loose or gritty.
  • Case sizePraisedThe 40 mm case and 12.5 mm thickness are called comfortable on average wrists.
  • LumeMixedNight visibility is usable but weaker than on more expensive divers, some owners say.

Questions and answers

Is the Tissot Seastar 1000 Powermatic 80 a real dive watch?
Yes. It is rated to 300 m, has a screw-down crown, a unidirectional rotating bezel and a sapphire crystal. That covers recreational diving and everyday swimming.
How long does the Powermatic 80 run without winding?
About 80 hours on a full wind, so it keeps going through a long weekend off the wrist. Wear it regularly or wind it by hand after longer breaks.
Does the 40 mm case fit small wrists?
It suits most wrists from about 6.5 inches up. The 12.5 mm thickness and 20 mm lugs keep it from feeling bulky.
Can I swap the bracelet for a strap?
Yes. The 20 mm lug width takes most aftermarket straps, and many owners fit a rubber or NATO strap for swimming.
How does it compare with the Longines HydroConquest?
The Tissot has the longer power reserve and a smaller case option. The HydroConquest offers better finishing and a more refined bracelet for more money.
Is the turquoise dial version different from the black one?
Only the dial. Movement, case, bracelet and 300 m rating are the same across the Seastar 1000 Powermatic 80 line.
