Vacheron Constantin Patrimony Retrograde Day-Date 4000U/000P-H003 Platinum 42.5mm Salmon Dial 
 This beautiful timepiece comes with the outer black box, inner black box, passport booklet, warranty card, dated September 2023, and both hangtags.  The Calibre 2460 R31R7/3 uses a complex system of cams and springs to make both the day and date hands instantly jump back at month’s end, a precise mechanism few manufactures attempt because of the engineering difficulty and power-management challenges.  The watch is in nice pre-owned condition. The watch shows minor cosmetic wear. Mechanically the watch is functioning as it should. Serial # and names are blurred for privacy reasons.
