Luminor 1950 3 Days Acciaio 47

The Panerai PAM00422 Luminor 1950 3 Days Acciaio 47 is a 47 mm stainless-steel diver built around the manufacture calibre P.3000, one of Panerai's first fully in-house movements. Its black sandwich dial carries luminous Arabic numerals, preserving the legibility that has defined the Luminor line since its military origins. Produced from 2013 to 2019, the reference occupies a central place in the modern Panerai catalogue as a statement of in-house watchmaking at the brand's most iconic case size.

The Luminor 1950 case, distinguished by its cushion profile and patented crown-protecting bridge, was introduced as a historically faithful reinterpretation of mid-twentieth-century Panerai references supplied to the Italian Navy. The PAM00422 arrived in 2013 as part of a broader effort by Panerai to replace ébauche-based movements with proprietary calibres, with the P.3000 representing a significant milestone in that programme. The reference remained in regular production through 2019, giving it a solid six-year run that allowed it to become well established among collectors who prize the combination of in-house movement and the full 47 mm format.
