Tissot Seastar 1000 Quartz Chronograph 38mm Unisex Watch

Ref. T1202173706100

The Seastar 1000 has historically lived at the larger end of Tissot's sport catalogue, and the 38mm chronograph introduced in 2025 represents a deliberate step toward a more wrist-neutral size — one that keeps the 300-metre rating and full chronograph architecture but fits a broader range of wrists without the bulk the 45mm variant demanded. This all-black reference takes that proposition further: PVD case, black silicone strap, and a graded grey-black dial with three sub-dials, so nothing pulls focus from the instrument itself. The ETA G15.212 Precidrive inside is a sealed, battery-powered calibre — accurate and unfussy, but not one to be serviced in the traditional sense. What it adds here is the split and add functions alongside the 30-minute and 1/10-second counters, which puts this closer to a genuine timing tool than a dressed-up stopwatch. Tissot's quick-release system means the strap swaps without tools, which matters if the watch moves between silicone for the water and something else for the desk.
