The birth of the device protecting the winding crown
The Special Edition created by Officine Panerai is the Luminor 1950 3 Days. In this model, the brown dial is fitted in a Luminor 1950 case, immediately recognisable by the bridge-shaped device with its locking lever which exercises a light pressure on the winding crown to protect it from accidental shocks and to help ensure the watch’s water-resistance. This device had certainly been invented and used even earlier, perhaps even before the end of the 1940s, but the patent application was only lodged as late as 1955, probably delayed because of the military secrecy imposed by the Italian Navy.
The new Luminor 1950 3 Days has the Luminor 1950 case of AISI 316L stainless steel, in its first historic version: the one with a diameter of 47 mm, its cusped shape reminiscent of the cases of the first Radiomir watches.
The distinctive, original element of the model is the brown dial, its colour inspired by that of the vintage watches which have undergone the discolouring effect caused by the luminous material. The substance used today to achieve exceptional night visibility, typical of all Panerai watches, is Grade A Super-LumiNova®, applied to the incisions made in the dial corresponding to the classic, large markers which indicate the hours.
Through the sapphire porthole on the back of the new Special Editions, the hand-wound P.3000 calibre, entirely made in the Panerai Manufacture in Neuchâtel, can be admired. The P.3000 has two spring barrels which enable it to accumulate a power reserve of three days and it is here presented for the first time with a new appearance.
The model is supplied with a Ponte Vecchio strap in brown leather with visible ecru sewing, the heat-engraved OP logo and a tongue buckle in polished steel personalised Panerai. The watch is water-resistant to 10 bar (equivalent of a depth of about 100 metres).
