TIS20 Tissot Seastar 1000 Chronograph. Reference T066.417.17.057.01. Watch measures a cool 45mm and is made from steel. Swiss high precision quartz movement caliber ETA G10.212. Sapphire crystal on the front and a closed case back. Waterproof 30ATM or 300 meters. Functions are hours, minutes, sub seconds, chronograph and date. Red ceramic rotating bezel for diving. This watch is fitted with the original black rubber strap with steel pin buckle. This watch is complete with the original box and booklet but sadly the warranty card has been misplaced by the original owner. However our watchmaker serviced this watch (January 2021) so we can happily warrant the watch for 6 months. A rarer version of this very popular diving watch!
