T120.907.37.051.00 Description Discover the new Seastar 44mm Powermatic 80. This new edition has undergone a subtle transformation, incorporating a notch along the edges of the case, resulting in a more compact and sophisticated appearance. This automatic timepiece is the perfect watch for those in search of a sporty yet assertive accessory. Certified according to the ISO 6425:2018 diving watch standard, it meets the strict requirements expected of professional diving instruments. Equipped with a helium escape valve, it is designed to perform reliably during saturation diving by allowing helium particles accumulated inside the case to safely escape during decompression. The watch is water-resistant up to a pressure of 60 bar (600 metres / 2,000 feet) and offers excellent legibility in low-light conditions thanks to its Super-LumiNova® coated hands and hour markers. Straps and bracelets can be interchanged using Tissot’s easy-to-use quick strap change system, giving the owner the opportunity to choose from a wide range of compatible Tissot straps and personalise their watch to suit mood or occasion. Discover the unique aesthetic of this black PVD version with its ceramic bezel ring, black gradient dial and matching black rubber strap, following the collection's signature sporty yet bold appeal.
