The Tissot Seastar 2000 Professional Powermatic 80 [T120.907.17.041.00] is the most capable diving watch in the modern Tissot collection, engineered for serious underwater exploration while remaining versatile enough for daily wear.

Designed to exceed the expectations of professional divers and enthusiasts alike, the Seastar 2000 Professional combines extreme water resistance, advanced materials, and proven Swiss mechanical performance into one of the most compelling dive watches in its class.

The dial features a striking blue gradient finish, transitioning from vivid oceanic blue at its centre to a darker outer perimeter. This fumé effect creates remarkable visual depth while maintaining outstanding legibility. Large luminous hands and indexes ensure visibility in challenging underwater environments and low-light conditions.

Surrounding the dial is a robust black ceramic unidirectional rotating bezel. Ceramic provides superior scratch resistance and long-term durability while enhancing the premium feel of the watch.

The defining feature of the Seastar 2000 Professional is its extraordinary 600 metre (60 bar / 2,000 ft) water resistance, placing it firmly within the category of serious professional dive instruments. Complementing this capability is a dedicated helium escape valve, a feature typically associated with substantially more expensive professional diving watches.

At its heart beats Tissot's renowned Powermatic 80 automatic movement, delivering up to 80 hours of power reserve. Enhanced by a Nivachron™ balance spring, the movement offers improved resistance to magnetic fields, shocks, and temperature variations encountered in everyday life.

The substantial 46 mm stainless steel case is purpose-built for professional diving while the integrated black rubber strap provides comfort, flexibility, and security whether worn over a wetsuit or directly on the wrist.

Turning the watch over reveals a sapphire exhibition caseback, showcasing the movement while maintaining the robust construction expected of a professional diving instrument.

This is not simply a dive watch.

It is Tissot's flagship mechanical diver — a purpose-built professional tool watch engineered for those who demand capability, durability, and Swiss mechanical reliability.
