Blancpain Villeret Rose Gold — Grey Complete Calendar with Moon Phase | Ref. 6654 3613 55B

Founded in Villeret, Switzerland in 1735, Blancpain holds the singular distinction of being the world's oldest watch brand — a heritage that lends every piece from its storied ateliers an authority no newcomer can replicate. The Villeret collection is the purest expression of this legacy, embodying the dress-watch tradition of the Vallée de Joux through architectural restraint, double-stepped bezels, and movements of consummate finish.

Powering this rose gold Complete Calendar is the automatic Calibre 6654.4, a self-winding movement delivering 72 hours of power reserve. Three subsidiary dials present the day of the week, date, and month in perfect symmetry, while a precisely rendered moon-phase display at six o'clock — accurate to one day's error in 122 years — affirms the enduring poetry of watchmaking's bond with astronomy. Under-lug correctors allow discreet calendar adjustment without tools.

Cased in warm 18-carat rose gold and water-resistant to 3 bar, the 6654 3613 55B is presented on a supple grey alligator leather strap, its Gstaad buckle polished to a mirror finish. For the discerning collector who values functional elegance over ostentation, this Complete Calendar represents Blancpain's mastery of classical complications at their most wearable — a timepiece destined to become an heirloom.
