This watch fully deserves the designation Survival Instrument engraved on the back with the image inspired by frogman commandos of the Italian Navy. For decades, Panerai watches and precision instruments have equipped the commandos of the Italian Navy. Panerai still makes creations of invincible spirit which evoke the legendary history of those special forces. The latest creations are professional underwater watches of remarkable technical performance with a solid Carbotech case. The unidirectional rotating bezel enables the times of immersion to be calculated with confidence, while legibility in the dark is ensured by Super-LumiNova® coating applied to the markers and the large skeleton hands. The rubber strap fitted to the watch is perfect for diving and very tough.
