Setup, Compatibility & Care
To ensure your Tissot Seastar 2000 remains in peak condition, always ensure the screw-down crown is fully pushed in and tightened before water exposure. The watch should be rinsed with fresh, lukewarm water after exposure to saltwater to prevent mineral buildup and corrosion on the bezel mechanism. Keep the watch away from strong magnetic fields, which can affect the accuracy of the Powermatic 80 movement. If the watch is not worn regularly, wind the crown 20-30 times to ensure the mainspring is sufficiently charged. For service or component replacement, only use authorized Tissot service centers to maintain the integrity of the 60 bar pressure rating.
