The Tissot Seastar 1000 is the ultimate watersport watch, with its high water-resistance up to a pressure of 30 bar (300 m/1000 ft), screw-down crown and caseback as well as its unidirectional ceramic bezel. Features: Automatic movement 80 hour power reserve 42 mm See-through case back Sapphire crystal Micro adjustments on clasp This watch was purchased in 2019 and was recently serviced by Tissot in December of 2023. Since it has come back from service I have not worn it as there are other watches that I prefer. It is in perfect operating condition, but does feature scratches throughout the stainless steel casing and links for typical daily wear. Comes with travel case, original box, and extra links.
