Patek Philippe Grand Complications 27000M-001

Patek Philippe combines tradition and innovation in a perpetual calendar and weekly calendar desk clock featuring a new manually wound caliber with a 31-day power reserve, +/- 1 second per day rate accuracy and user-friendliness worthy of a 21st-century timepiece.

Resulting from a seven-year development process, the new rectangular 86-135 PEND S IRM Q SE caliber (912 components) has led to nine patent applications. To guarantee optimum performance, engineers have designed a genuine “precision regulator” at the heart of the movement.

This new Sterling Silver timepiece is also distinguished by its refined, timeless exterior enhanced by green flinqué Grand Feu enamel.
