Tissot’s grey Seastar 2000 Professional is built for serious depth

Tissot’s 2026 Seastar 2000 Professional reference T120.907.11.051.00 pairs a grey-gradient wave dial with a black ceramic dive bezel and a full stainless-steel bracelet. The redesigned case measures 44mm across and 15.29mm thick—smaller than the preceding 46mm generation—while retaining ISO 6425:2018 certification, a helium escape valve and 600 metres of water resistance.

The Powermatic 80 automatic movement provides up to 80 hours of reserve and uses a Nivachron balance spring. It is visible through the sapphire caseback. Large Super-LumiNova-coated hands and markers support low-light reading, and the date remains at six o’clock. This 209-gram bracelet model also receives Tissot’s revised diver clasp with a security lock and push-button extension. Its European launch price was €995.
