PAM 00643 The case of the Radiomir Ceramica - 45 mm bears the same design as officine Panerai's original, historic watch, made in 1938 for the Italian Navy. The Radiomir Ceramica - 45 mm is evocative of the actions of the men of the Gamma group in the Italian Navy, who, during the Second World War used so-called SLC, slow torpedoes, also known as "black seals" for their missions. This Panerai watch model stood out for its case's structure, which guaranteed a high degree of impermeability thanks to its winding crown and the screwed-on case-back, while Radiomir, a luminescent paint containing zinc sulphur, mesothorium and radium bromide, gave the dial excellent visibility even in extreme conditions of use. The ceramic used for the case is worked from a powder using an isostatic pressure process that enhances the material's extreme hardness, great resistance to extreme temperatures and corrosion Case Size: 45mm Buckle: Tang Materials: Ceramic Dial: Black hobnail Movement: Manual OP X calibre Water Resistance: 10 bar Complications: Hours, minutes Case Back: Plain Strap : Black calf Reference #:PAM00643 CALL DURING HOURS FOR PRICING OR EMAIL
