TIS24 Tissot Heritage 1936. Reference T104.405.16.012.00. Watch measures a cool 45mm and is made from steel. Manual winding movement base caliber Unitas 6497. Sapphire crystals on both sides of the case. Waterproof 5ATM or 50 meters. Functions are hours, minutes and small seconds. This watch has a so called demi-savonette case which means you can open the case back and view the very nice Unitas movement. This watch is fitted with the original brown leather strap (brand new and unused). The original used bracelet is also with the set. This strap can be glued and used again and can serve as an extra. Naturally this watch is complete with the original box and papers dated 2017. Please be aware that this was a one-owner watch who wore it carefully and the watch has never been polished. A fantastic and quite rare Tissot that is becoming collectible!
