PRODUCT DETAILS
The Tissot Seastar 2000 Powermatic 80 features a 44 mm black PVD-coated 316L stainless steel case with a notched edge and a scratch-resistant ceramic bezel ring. Engineered to meet the ISO 6425:2018 diving watch standard, it incorporates a built-in helium escape valve designed for professional saturation diving.
Powered by a Swiss automatic Powermatic 80 movement, this timepiece delivers up to 80 hours of power reserve and includes a patented Nivachron balance spring for enhanced magnetic field resistance. Super-LumiNova coating on the hands and hour markers ensures clear legibility against the gradient dial in low-light environments.
Rated water-resistant up to 60 bar (600 m), the watch is fitted with a screw-down crown, screw-down caseback, and a sapphire crystal with an antireflective bottom coating. An interchangeable quick-release black rubber strap allows for easy, tool-free customization.

WATER RESISTANCE
Please check the marking on the back of your watch case and refer to the following table to confirm the degree of water resistance of your watch and the preferable conditions of use. A watch’s water resistance is not permanently guaranteed. It is affected by the ageing of gaskets or deformation of watch parts due to accidental shock. To preserve a watch’s water resistance as long as possible, please follow the precautions below:
- Wipe off moisture, sweat or dirt with a soft dry cloth after removing it from the wrist in order to increase the durability of the case back, gaskets and band.
- After using a water resistant watch in ocean water, wash it in fresh water and dry it with a soft cloth.
- Do not wash a water resistant watch while the crown is pulled out.
- Do not operate the crown or press a button when the watch is wet.
- A periodic overhaul service is recommended to check the water resistance of the watch regularly to ensure it’s functionality.
