GOOD TO KNOW
• Exceptional quality split-seconds perpetual calendar in a left-handed configuration
• First appearance of a ref. 5373P at public auction
• Like new, fresh-to-market, and complete set

Patek Philippe has a long and unbroken history with perpetual calendar chronographs starting with the reference 1518 in 1941, but it wasn’t until 1996 and the launch of the reference 5004 that Patek Philippe added a split seconds mechanism to a serially produced perpetual calendar chronograph, once again asserting the brand’s technical supremacy. However, Patek Philippe had always relied on outsourced movements for its chronographs (Valjoux, Lemania) and in 2010 the brand presented its very first perpetual calendar split-seconds chronograph with in-house movement: the reference 5159, an elegant monopusher model in a cushion case.

The Patek Philippe Grand Complications 5373P-001 stands as a remarkable creation, being the first chronograph designed specifically for left-handed collectors in the brand's recent history. Also known as a “destro”, its 38.3 mm platinum case features an unconventional arrangement with the crown and monopusher at 9 o'clock and the split-seconds pusher at 8 o'clock, accommodating left-handed operation.
In classic Patek Phillipe fashion, the monopusher chronograph is combined with a perpetual calendar complication. This timepiece houses the manually wound caliber CHR 27-525 PS Q, renowned as the thinnest and finest split-seconds chronograph movement with a perpetual calendar ever crafted by Patek Philippe.
The charcoal gray dial, adorned with a black-gradient rim and vertical satin finish, exudes a contemporary and sporty aesthetic. Red varnished chronograph hands provide a striking contrast, enhancing legibility and visual appeal. Gold applied numerals further accentuate the dial's sophistication.
Appearing for the first time at public auction as of cataloguing, the present example is offered in like-new condition with all its accessories including an additional caseback.
