Tissot reference T120.907.37.041.00 combines the new 44mm Seastar 2000 Professional architecture with a black-PVD-coated steel case. A blue-gradient wave dial supplies the colour, framed by a black ceramic unidirectional bezel and matched to a black tropic-style rubber strap. The 15.29mm-thick case remains ISO 6425:2018 certified and water-resistant to 600 metres, with a screw-down crown and helium escape valve.

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.

Reference T120.907.37.051.00 is the most monochromatic of Tissot’s five 2026 Seastar 2000 Professional editions. Its black-gradient wave dial sits inside a black ceramic timing bezel, while black PVD covers the 44mm steel case and a black rubber strap completes the treatment. The case is 15.29mm thick, ISO 6425:2018 certified and rated to 600 metres with a helium escape valve.

The brightest member of Tissot’s 2026 Seastar 2000 Professional family is reference T120.907.17.281.00. Its orange-gradient dial retains the collection’s engraved wave pattern but adds a black outer section, black ceramic timing bezel and black rubber strap. The steel case measures 44mm by 15.29mm and combines ISO 6425:2018 certification with 600-metre water resistance and a helium escape valve.

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.
