The Submersible Marina Militare Carbotech™ has decidedly military features, in both its character and its rigorous quality. It fully deserves the designation Survival Instrument which is engraved on the back together with the image inspired by commandos of the Italian Navy. The case, 47 mm in diameter, is made of carbotech, a material based on carbon fibre which was introduced into the world of high quality watchmaking by Panerai.
