Audemars Piguet Quantième Perpétuel: Unveiling a Rare Salmon Dial Reference

Key Points from the Discussion

• The featured watch is a perpetual calendar, not an annual calendar, despite the absence of a visible leap year indicator on the dial. The 'Quantième Perpétuel' designation inherently confirms its perpetual calendar functionality.
• The caliber 2120/2800 and 2120/2804 movements used in AP QPs incorporate a 12-month star wheel with two cams and a Maltese cross for leap year tracking, even if a dial-side indicator is not present. This design choice, particularly the lack of a visible leap year indicator on some QP models, is a point of historical curiosity.
• The salmon dial on this specific white gold reference is exceedingly rare, with only about ten pieces delivered to the Italian distributor GGV in the mid-1990s. While other dial variations like Breguet and Tuscan dials existed, salmon was exclusively paired with white gold, and Tuscan dials only with platinum.
• The movement of this specific series, produced between 1985 and 1994 (C-D series), features a decorated and finished caliber. Adjustments to these complex movements would typically be handled by an authorized Audemars Piguet dealer.
