Patek Philippe Grand Complications 27000M-001

Patek Philippe perpetuates its rich heritage by drawing inspiration from a desk clock with perpetual calendar and eight-day power reserve delivered in 1923 to American collector James Ward Packard, as well as from a model of the same type sold in 1927 to another notorious American collector, Henry Graves Junior. To effectively combine tradition with innovation, the Manufacture has developed a new manually wound caliber offering exceptional performance: a 31-day power reserve and rate precision of +/- 1 second per day, along with the user-friendliness of a timepiece designed for the 21st century.

• Desk clock with perpetual calendar, weekly calendar and 31-day power reserve.
• Manual winding caliber 86-135 PEND S IRM Q SE (912 components). Nine patent applications. Constant-force mechanism ensuring a rate accuracy of +/- 1 second per day.
• Week number indicated through a mobile frame. Central indication of the power reserve by hand (31 days). Central jumping seconds.
• Sterling silver cabinet with vermeil decorative elements. Green Grand Feu flinque enamel panels guilloched with a swirling pattern.
