This is a gorgeous and extremely rare Tissot Navigator oversized chronograph circa apporximately 1967. This is one of the first larger cased chronographs similar to the Zenith A. Carelli, Bulova Marine Star, and Breguet Type XX. Inside is the Lemania 872 manual wind movement in excellent working order. Everything is original including the dial, hands, signed crown and pushers, and crystal. Comes on a beautiful leather strap to highlight the patina of the dial in addition to the original bracelet as shown. A true rare gem.
