TIS13 Tissot Seastar 1000. Reference T066.407.17.057.02. Watch measures 42mm and is made from steel with a ceramic bezel. Automatic Tissot movement caliber ETA C07.111 (Powermatic 80). Sapphire crystals on both sides of the case. Waterproof 30ATM or 300 meters. Functions are hours, minutes, sweep seconds and date. This watch is fitted with the original black rubber strap with steel pin buckle. Naturally this watch is complete with the original box and booklets but sadly the original owner lost the warranty card while moving house. The original owner bought the watch new but has never worn it so the watch is in new condition. Great value for money for an automatic diving watch with an open case back!
