Tissot Seastar 1000 Quartz 40mm Mens Watch

Ref. T1208521105100

The Seastar sits within Tissot's T-Sport line as an original design rather than a revival — no vintage reference behind it, no anniversary to mark, just a clear brief to build a capable diver with a second time zone readable at a glance. The GMT hand is green, which ties it visually to the bi-colour black-and-green bezel and gives the dial a point of difference from the plainer siblings in the same generation. At 11.77mm thick for a watch rated to 300 metres, the case is noticeably slim — most divers at this depth rating carry considerably more height, and this one will actually disappear under a shirt cuff. The black dial and luminous indexes keep things legible in low light, and the date sits at six o'clock rather than interrupting the chapter ring. The brushed and polished three-link bracelet is quick-release, which makes swapping to a strap straightforward without tools, and the deployant clasp handles the 148g weight without shifting on the wrist.
