In 2013 Panerai surprised collectors with two new vintage-inspired models featuring historic Minerva-based movements and this time with 12-sided bezels: the Radiomir Platinum, ‘PAM 521’ and the red gold ‘PAM 522’. These special limited editions of 100 pieces each sport a cushion shaped case measuring 47mm with wire loop strap attachments and Plexiglas crystal. The overall vintage appeal of both watches is enhanced through the addition of an original-style spherical winding crown. The hand-wound movement, Panerai ‘OP XXVII’ caliber with a power reserve of 55 hours is based on the Minerva caliber 16-17. The 12-sided bezel was inspired by a small number of original watches that were made in the late 1930s for the Panerai shop in Florence. Engraved with the inscription “OFFICINE PANERAI – BREVETTATO” referring to the patent of the luminous substance ‘Radiomir’. Originally featuring on the bezel of the historic models, the engraving now appears on the back edge, surrounding the sapphire crystal.

Panerai’s decision to manufacture these models using historic Minerva-based movements resulted in some of the most attractive and desirable modern wristwatches made by the company. Perfect vintage styling, taking the best elements from Panerai’s design heritage, combined with state-of-the-art modern manufacturing know-how, precious materials and the highest level of watchmaking needed to transform vintage Minerva movements to create new Panerai calibers endows these references with true personality, ensuring the genius of Panerai’s historic past is secure in the present day.
