Our take on the Tissot Seastar 1000 Powermatic 80 (T120.807.11.051.00)

The Seastar 1000 Powermatic 80 is Tissot's entry-level Swiss dive watch: a stainless steel case and bracelet, sapphire crystal, 300 m water resistance and an automatic movement with an 80-hour power reserve. It sits below the Longines HydroConquest and Oris Aquis in price and finishing, but beats most sub-$1,000 divers on specs. The black dial with applied indices and a date at 6 o'clock is clean and legible. It suits buyers who want a real dive watch with Swiss automatic movement for daily wear, not a collector's safe queen.

What reviewers say

Owners and reviewers treat the Seastar 1000 Powermatic 80 as strong value: a genuine 300 m Swiss automatic diver with sapphire and a long power reserve. Common complaints are its thickness and weight, a clasp that feels ordinary, and lume that is adequate rather than excellent.

What people mention
  • Case sizeMixedOwners like the presence but many find the case thick and heavy, especially on wrists under about 7 inches.
  • Power reservePraisedThe 80-hour reserve lets it sit over a weekend and still run, which reviewers call a standout for the class.
  • BraceletMixedThe steel bracelet is solid, but the clasp and finishing are described as plain next to more expensive divers.
  • LumeCriticisedReviewers say the lume glows fine at first but fades faster than Seiko or Citizen divers.
  • Water resistancePraisedThe 300 m rating, screw-down crown and sapphire crystal give owners confidence for swimming and diving.
  • AccuracyMixedOwners report the automatic movement keeps good time but drifts more than chronometer-rated watches.

Questions and answers

Is the Seastar 1000 Powermatic 80 a real dive watch?
Yes. It has 300 m water resistance, a screw-down crown and sapphire crystal, so it is rated for swimming and recreational diving. It is not a certified professional dive instrument.
How does it compare with the Longines HydroConquest?
The Tissot gives you similar specs, including 300 m and a long power reserve, for less money. The HydroConquest has better finishing and brand prestige.
Is it too big for small wrists?
It is a thick, heavy watch. Shoppers with wrists under about 7 inches often find it top-heavy; try it on if you can.
Does it have a screw-down crown and date?
Yes. The crown screws down for water resistance, and there is a date window at 6 o'clock.
What is the power reserve?
About 80 hours when fully wound, so it keeps running through a weekend off the wrist.
What comes in the box?
The watch on its stainless steel bracelet, a Tissot box and paperwork. No extra strap is included.
