Complicated Desk Clock ref. 27000M-001 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.
