Tissot Seastar 1000 Quartz 40mm Mens Watch

Ref. T1208522205100

The Seastar 1000 sits within Tissot's T-Sport line as a straightforward working diver, and this GMT variant in two-tone yellow gold PVD — sometimes called Root Beer — is the one that reads as something other than purely functional. The warm gold against brushed steel is a long-established colour pairing in sports watches, and Tissot applies it consistently across case, bezel and bracelet rather than as an accent, so the effect is coherent rather than decorative. At 40mm and 11.8mm thick, it wears closer to the wrist than most 300-metre-rated divers, which tend to sit taller to accommodate the case architecture that pressure resistance requires. The GMT hand adds a second time zone without complicating the dial — the black face with gold-tone markers stays legible, and the Super-LumiNova carries enough charge to read clearly in dark water. The battery end-of-life indicator means the quartz movement warns before it stops rather than simply stopping, which matters more than it sounds if the watch is worn as a travel tool. The quick-change strap system is worth knowing about before you commit to the bracelet. At 148g on steel, some owners will find the rubber alternative genuinely preferable for extended wear, and the bracelet can come off without tools.
