In the late 1930s, Panerai made a number of Radiomir watches with a special 12-sided bezel, engraved with the words «OFFICINE PANERAI – BREVETTATO». This inscription referred to the patented luminous substance Radiomir used on the dial, and it suggests that the watches were used not for military operations but for presenting to the authorities of the Royal Italian Navy, which was evaluating new instruments for underwater missions. The new Radiomir 3 Days Acciaio models are two Special Editions from the Panerai Manufacture in Neuchâtel, which for the first time reproduce all the fundamental characteristics of these vintage watches, respecting their identity and giving collectors the opportunity to appreciate a fascinating chapter in the Panerai story.
The first vintage detail of the new Radiomir 3 Days Acciaio watches is the 12-sided bezel in brushed steel, with smoothed, polished angles and the same engraving as the historic models, using the lettering of the time. The bezel is screwed onto the classic cushion caseband of the Radiomir and, together with the screwed back forming the rear part of the case.
The P.3000 movement also has the device for quickly changing the time, enabling the hour hand to be moved backwards or forwards in jumps of one hour, without interfering with the movement of the minute hand or the running of the watch.
