Our take on the Tissot Seastar 1000 GMT 40mm

The Seastar 1000 GMT is a 40 mm steel dive watch rated to 300 m, with a Swiss quartz GMT movement, a 24-hour hand and a date. It stands out for its slim 11.77 mm case, sapphire crystal, Super-LumiNova lume and quick-release bracelet, which make it easy to wear daily and to swap straps. It suits travelers and divers who want a true GMT and real water resistance without the bulk or upkeep of a mechanical watch. Against mechanical GMT divers it trades a sweeping seconds hand and serviceability for accuracy, low maintenance and a thinner case.

Best forTravelers who track a second time zoneDivers and swimmers who want 300 m water resistanceBuyers who prefer quartz accuracy and low upkeepSmaller wrists that find 42 mm divers too big
Pros
  • True GMT with an independent 24-hour hand and date
  • 300 m water resistance with screw-down crown and caseback
  • Slim 11.77 mm, 40 mm case wears easily on most wrists
  • Sapphire crystal and Super-LumiNova lume
  • Quick-release bracelet makes strap swaps tool-free
  • Quartz movement needs no winding and about two years per battery
Cons
  • Quartz movement lacks the sweep and mechanical appeal some divers want
  • No rotating 24-hour bezel, so the GMT bezel is fixed
  • Battery replacement means opening the case every couple of years
  • Bracelet clasp and finishing are modest for the category

What reviewers say

Owners and reviewers treat the Seastar 1000 GMT as a well-built, honest dive watch with a useful GMT hand. They praise the slim case, the lume and the quick-release bracelet, and most criticism centers on the quartz movement and the fixed bezel.

What people mention
  • Case sizePraisedOwners say the 40 mm case and 11.77 mm thickness sit comfortably and suit smaller wrists.
  • MovementMixedReviewers like the quartz accuracy and low upkeep but miss the sweep of a mechanical GMT.
  • LumePraisedThe Super-LumiNova is called bright and long-lasting in low light.
  • BraceletPraisedThe quick-release system makes swapping straps easy without tools.
  • BezelCriticisedThe fixed 24-hour bezel is seen as less useful than a rotating GMT bezel.
  • BatteryMixedTwo-year battery life is convenient but means periodic case openings for service.

Questions and answers

Is the Seastar 1000 GMT a true GMT?
Yes. The 24-hour hand tracks a second time zone independently, and the watch also shows the date.
Can I swim and dive with it?
Yes. It is rated to 300 m with a screw-down crown and caseback, so it handles swimming, snorkeling and recreational diving.
How often does the battery need changing?
Tissot rates the quartz movement at about two years per battery. A jeweler or service center replaces it and reseals the case.
Can I change the bracelet myself?
Yes. The quick-release system lets you swap the bracelet or a strap without tools.
How does it compare with the automatic Seastar 1000?
The GMT is thinner, more accurate and cheaper to own, but the automatic version offers a mechanical movement and a rotating bezel.
What is in the box?
The watch on its steel bracelet, a presentation box and paperwork. Extra straps are sold separately.
