THE FIRST WATCH CALIFORNIA DIAL.

"One of the main characteristics of the Radiomir is its dial, of which several versions exist. The first to appear, as early as 1936, was the so-called “California” dial, with its distinctive alternation of Roman and Arabic numerals, bar markers and a railway track minute circle. But given the need to increase its visibility so that the commandos could use the watch in the most complete darkness, Panerai made the dial more luminous. "

AISI 316L STAINLESS STEEL

"AISI 316L 1.4435 stainless steel is Officine Panerai’s material par excellence since it is highly resistant to corrosion and is hypoallergenic, making it ideal for contact with the skin. The Panerai watches created for the Italian Navy were made of austenitic stainless steel, a reliable material that was also resistant to the extreme environmental conditions in which the commandos operated."

P.3000 CALIBRE

The P.3000 calibre, created entirely at the Panerai Manufacture, presents the main characteristics of the Panerai movements in terms of structure and robustness, accuracy and power reserve. The diameter of the calibre is 16½ lignes, a substantial size which traces its origins from that of the movements which were fitted to the historic Panerai models. The calibre is immediately recognisable by its construction, which is similar to that of a three-quarter plate movement: a large bridge, next to another smaller one, covers the majority of the mechanical parts, and is fixed to the bottom plate by a series of screws of substantial thickness, thus forming a particularly rigid structure. The movement has 21 jewels and it uses two spring barrels connected in series. Such an arrangement enables long, thin springs to be used, which ensure the delivery of a more even force over a longer period of time, with a power reserve of 3 days.
