The Patek Philippe Annual Calendar Regulator ref. 5235G-001 is the first Patek Philippe regulator watch from this manufacture. This exceptional timepiece fitted with a 40.5 mm white gold case and an in-house movement, is pure perfection at its best. Released six years ago at Baselworld 2012, surprisingly this timepiece is not one of the most popular references from Patek and nowadays is not even commanding a price premium but the complete opposite. As most of you know, a 'régulateur' a.k.a a regulator, is a watch with non-coaxial hour and minute hands, which means, that the hour and minute hands do not share the central pinion position on the dial but are independently placed.
