Patek PhilippeAnnual Calendar Chronograph

Offered by a private collector, this 2010 Patek Philippe Annual Calendar Chronograph is accompanied by its original lacquered wood box, official documents - including the certificate of origin and user manual - and date corrector tool. The vendor advises the watch is in mint condition, and it appears to be within the bounds of their ‘A’ grading.

Encased in platinum, this Annual Calendar is a Patek Philippe masterclass in complex watch engineering. The grey sunburst dial is characterised by the day, date, and month functions located at the 10, 12, and 2 o’clock markers, and the concentric chronograph totaliser at the six o’clock marker adds character and visual intrigue to this elegant chronograph watch. Its case is attached to a black leather strap with a platinum clasp in the form of the Patek Philippe ‘Calatrava Cross’ crest.

Beneath the rear sapphire crystal display case lies Patek Philippe’s CH 28-520 IRM QA 24H calibre. This 40-jewel automatic movement is the first of its kind from the Swiss watchmaker and has a power reserve of 55 hours.
