**Blancpain Tribute to Fifty Fathoms MIL-SPEC** A tribute to an iconic and historical dive watch from Blancpain that played a pivotal role in the history of diving watches. The Mil-Spec variant introduced in 1957 was specifically designed to meet military specifications, and included a **Moisture Indicator:** a distinctive feature on the dial. This small circle changes color if water enters the case, alerting the wearer to potential damage—a critical safety feature for divers. The Mil-Spec was adopted by various military organizations, including the French Combat Diving Corps and the U.S. Navy, due to its reliability and innovative design. **Tribute to Fifty Fathoms MIL-SPEC** retains the iconic moisture indicator and classic design. 40.3mm stainless steel case, sapphire bezel, black dial. Comes with two factory straps: factory black sail-canvas fabric strap with original buckle, and orange strap as shown. Blancpain Calibre 1151 movement with 210 parts and two main spring barrels producing four-day power reserve. The solid gold rotor has this NAC coating (a platinum alloy). Comes with original box, travel case, papers.
