Radiomir 3 Days Acciaio - 47mm Special Edition 2017 Manual-winding P.3000 calibre

The Radiomir is the first watch designed by Officine Panerai as a prototype in 1936 at the request of the Royal Italian Navy, which wanted to be supplied with “a special luminous watch for divers”. The generous dimensions, with a diameter of 47 millimeters, and the cushion shape, with sides shaped to protect the dial, made it very resistant, while the three-part construction with a screw-on back and screw-down winding crown ensured maximum water-resistance.

Other features of the Radiomir were the wire loop strap attachments, welded directly to the case, and its wide strap, water-resistant and long enough to be worn over the diving suits used by the frogman commandos. As for its name, this refers to the material used on the dial, a very luminous material – patented by Panerai – which made the Radiomir ideal for the underwater use for which it was designed.
