Limited Edition Luminor 31 Giorni 44mm Watch PAM01631

The Luminor 31 Giorni PAM01631 is a landmark milestone in Panerai’s pursuit of extended autonomy. For the first time, the Maison introduces a watch capable of running for an entire month on a single wind, pushing beyond the limits once defined by its celebrated 8 Giorni and later 10 Giorni movements. This continues a legacy shaped by Panerai’s early instruments developed for the Italian Navy, where reliability and long-lasting performance were essential during missions.

A pillar that finds its most advanced expression through the work of Panerai’s Laboratorio di Idee, where seven years of research and development resulted in the new P.2031/S hand-wound skeleton calibre with an unprecedented power reserve length enclosed within a 44 mm Goldtech™ Luminor case. The challenge was to achieve unprecedented autonomy while preserving stability, legibility, and ease of use. The result is a movement that balances technical ambition with Panerai’s unwavering focus on robust, functional watchmaking.

The polarized date display preserves the visual openness of the movement while ensuring the date remains clear and easy to read. The date disc interacts with polarized light so that the numerals appear only through the dedicated aperture at 3 o’clock. Everywhere else, the disc remains invisible to the eye, allowing the mechanics of the movement to remain fully visible without interruption.
