The Seastar 2000 Professional is a new and technically advanced dive watch from Tissot.
Water-resistant to 2000 feet (60ATM/600 meters), this high-performance diving watch meets all the criteria of the ISO 6425 standard that governs dive watches. This chunky tool watch in stainless steel measures 46mm diameter and 16.25mm thickness. Dedicated to enthusiasts of extreme nautical style, it features a ceramic diving bezel and a very thick, bulging, domed sapphire glass with a bevelled contour.
The Seastar 2000 Professional watch is equipped with a robust, precise and high-performance self-winding movement. The Powermatic 80 calibre has a power reserve of 80 hours. The Nivachron™ hair-fine spring of the movement is made of a titanium-based alloy, which is completely resistant to magnetism.
This date is displayed in a metallic aperture at 6o’clock, in transfer form on a black background. It is in keeping with the rest of the watch, in particular its dial in shades of blue ranging from the darkest deep-sea blue, on a background pattern of waves designed especially for the Seastar 2000 Professional.
The case is of 316L-type steel, the most effective steel alloy for combating corrosion. Its flat surfaces are burnished and its vertical sides are satin-finished, including the shoulder that surrounds the crown and protects it from shocks.
Underneath, the case back is of transparent sapphire, extremely rare for this degree of pressure resistance, which usually callsfor sturdy metal case backs. On it, Tissot has placed a transfer of a seahorse, symbol of its dive watches. And on top of this ensemble, Tissot has installed the indispensable dive bezel.
Its bezel is made of steel, with a rim marked with deep notches. These are intended for improved grip, even with wet hands or with gloves, so as to ensure precise definition of the diver’s immersion time. The graduated 60-minute insert is made of black ceramic into which Arabic numerals are cut.
This bezel turns only in an anti-clockwise direction. This means that any accidental adjustment can only shorten the dive time, not lengthen it, which would be dangerous for the diver.
The Seastar 2000 Professional has been designed for professional divers, who work at considerable depths and have to remain there in extreme conditions. For this type of use, the case is fitted with a helium valve at 9o’clock.
The US retail price of the Tissot Seastar 2000 Professional Powermatic 80 automatic watch with the blue gradient dial is $ 1025.00. The black dial version (reference T120.607.17.441.00) costs $ 995.00.
