PAM01631Ref

Introduced in 2026 as a 200-piece limited edition, the Panerai Luminor 31 Giorni PAM01631 continues the brand's power-reserve tradition with a 31-day reserve, surpassing earlier 8 and 10 Giorni models. Its 44mm Goldtech case has a cushion shape and crown-protecting bridge, water resistance of 10 bar (~100m), and a black rubber strap with the PAM Click release system plus an extra strap. The skeletonized P.2031/S hand-wound movement uses four barrels, torque management, a jumping hour mechanism, and a polarized date at 3 o'clock, while the openworked dial shows central hours/minutes, small seconds, date, and power reserve.
