Only Watch 2021 – complicated desk clock, ref. 27001M-001

This exceptional timepiece was sold for 9.5 million Swiss francs on November 6, 2021. Patek Philippe is proud and delighted that this amount is being remitted to the Monaco Association against Duchenne Muscular Dystrophy as a contribution to the development of therapies against degenerative neuromuscular disorders.

A new high-performance movement

The ref. 27001M-001 is equipped with the new rectangular manual caliber 86-135 PEND IRM Q SE, featuring a perpetual calendar, moon phases, week-number display and power-reserve indication (31 days). Composed of 919 parts, it is the result of seven years of development work accompanied by nine patent applications. It is adjusted to a precision rate of -1/+1 second per day, meeting the extremely rigorous requirements of the Patek Philippe Seal.

A precious work of art

The ref. 27001M-001 is inspired by a desk clock delivered to James Ward Packard in 1923 and now safeguarded in the Patek Philippe Museum. The designers gave it an innovative touch, endowing it with a very practical control panel beneath a hinged cover. The case in 925 silver carries veneers of precious American walnut in reference to Packard’s homeland and is decorated with traditional screen-printed gold fillets. On the front of the cabinet, “The Only One” inscription recalls the exclusive character of this creation intended to support research into Duchenne muscular dystrophy.
