Luminor 1950 Marina 47 3 Days Stainless Steel / Black

In Context

At 47 mm this is exceptionally large for something worn on a wrist, closer to a pocket watch given lugs. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 72 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

PAM00422 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case.

Entirely designed, developed and produced at the Officine Panerai Manufacture in Neuchâtel, the hand-wound P.3001 calibre presents the main characteristics of the Panerai movements both in terms of structure and in terms of performance, robustness and accuracy. The thickness of the P.3001 calibre is 6.3 mm and the diameter 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. The P.3001 has the power reserve indicator visible on the case back and may feature the date or GMT functions. The number of components varies according to the functions displayed on the dial.
