What to know

Reference T120.907.17.041.00 gives the 2026 Seastar 2000 Professional a coherent deep-blue identity. Its gradient wave dial, ceramic bezel insert and tropic-style rubber strap all use closely related shades, leaving the steel case and luminous markers to provide contrast. The 44mm case is 15.29mm thick and rated to 600 metres, with ISO 6425:2018 dive-watch certification and a helium escape valve.

Tissot’s Powermatic 80 automatic calibre supplies up to 80 hours of power reserve and includes a Nivachron balance spring. A sapphire display back reveals the movement, while a domed sapphire crystal protects the dial. The rubber strap reduces the complete watch to 130 grams and uses Tissot’s quick-release system. Available immediately at launch, the blue version was priced at €975 in Europe.
