Overview
The split-seconds perpetual, turned for the left wrist
The Patek Philippe Grand Complications Split-seconds Monopusher Chronograph for Left-handers, Perpetual Calendar, reference 5373P-001, in platinum with the crown at 9 o'clock, a charcoal grey vertical-satin dial with black-gradient rim and red chronograph hands, on a black calfskin strap with red stitching. Manually wound calibre CHR 27-525 PS Q; 38.3 mm, 12.93 mm high.
The reference 5373P-001 is Patek Philippe's split-seconds monopusher chronograph with perpetual calendar built for left-handers: the brand describes it as the reference 5372 with crown, pushers and displays inverted, produced in a small series. The crown sits at 9 o'clock and the split-seconds pusher at 8 o'clock, in a platinum case 38.3 mm across and 12.93 mm high with a polished concave bezel, recessed satin-finished flanks and a diamond set at 12 o'clock. The dial is charcoal grey with a vertical satin finish and a black-gradient rim, with applied numerals and faceted hands in white gold, red varnished chronograph hands and ebony black snailed counters.
The calibre CHR 27-525 PS Q is 7.3 mm high, which Patek Philippe states makes it the thinnest split-seconds chronograph with perpetual calendar the brand has produced. It is wound by hand and runs at 21,600 semi-oscillations an hour on a Breguet balance spring, with 476 parts and 31 jewels across 27.3 mm, and a power reserve of 38 to 48 hours with the chronograph disengaged. The chronograph is a split-seconds monopusher with a 60-minute counter and small seconds; the calendar shows the day, month, leap year and day/night indication in apertures, the date by hand, and the moon phases. It carries the Patek Philippe Seal.
For collectors
Two things mark it out: the inversion for the left wrist — crown at 9 o'clock, split pusher at 8 o'clock, the displays mirrored from the 5372 — and the movement's height, 7.3 mm, which the brand states is the thinnest of its split-seconds perpetual calendar chronographs. Patek Philippe adds that it is produced in a small series.
