Set high on the European continent in Switzerland’s western Canton of Vaud is the village of Le Brassus, home to the world’s oldest surviving watchmaker, Blancpain. North of Geneva by about 60km, Le Brassus has its own unique identity, separate from that of Swiss watchmaking’s other home. These two factors – longevity and exclusivity – come together in Blancpain’s work, including today’s incredible timepiece, the Le Brassus 18kt Perpetual Calendar.
True to its name, the Blancpain 4276-3642-55B shows off some powerful timekeeping abilities in its myriad calendar functions. All within the 42mm case exists a moonphase, day, date, month, and even a GMT function, providing the ability to tell time in a second timezone. The powerful functionality is – impressively – controlled solely via the crown at 3 o’clock and the recessed buttons on the case’s side. Accurate until the year 2100, the perpetual calendar needs no adjusting as long as the movement is wound and serviced correctly – an incredible achievement of craftsmanship. And all this is to say nothing of the world-class design. Built from 18kt yellow gold, the simple yet perfectly curved case matches the combination pin/folding closure, emblazoned with the brand’s name. The movement, a Caliber 67A6, sits behind a closed caseback beating quietly and spins the simple, gold-finished hands including the red-tipped GMT and date pointers.
