The classic black dial of the new Luminor 1950 3 Days is supremely clear and readable, thanks to its design, its sandwich structure and its use of Grade A Super- LumiNova®. The case, 47 mm in diameter, is made of AISI 316L stainless steel with a polished finish and has the same proportions as the watch created by Panerai in the late 1940s, with its elegantly cusped caseband and the lever bridge device protecting the winding crown. Like the vintage models, which had crystals made of polymethyl methacrylate, the dial of the new Luminor is protected by a slightly domed Plexiglas® crystal, while the back has a large sapphire glass porthole enabling the Manufacture movement to be admired.
The P.3000 hand-wound mechanical calibre, with a power reserve of three days (two spring barrels), has a diameter of 161⁄2 lignes, a large size which has its origin in that of the movements which were fitted to the historic Panerai models. Solid and reliable, the movement has three satin- finished bridges protecting the movement and a further bridge with twin supports for the balance wheel 13.2 mm in diameter (vibrating at a frequency of 3 Hz). The P.3000 calibre also has the device for rapid time zone adjustment: a star wheel with 12 teeth and a small spring clutch enable the hour hand to be moved forwards or backwards in increments of one hour at a time without interfering with the movement of the minute hand or the running of the watch.
