The Patek Philippe Grand Complications (ref. 5373P-001) is a rare intersection of technical mastery and collector specificity – a left-handed chronograph with perpetual calendar in a platinum case. Released in 2022, it is the only current Patek Philippe reference featuring a split-seconds chronograph designed expressly for left-handers, with a reversed dial layout and crown on the left. The vertically satin-finished grey dial contrasts elegantly with applied blackened white-gold numerals and vibrant red chronograph accents.

The 38.3mm platinum case houses the ultra-thin, hand-wound calibre CHR 27-525 PS Q, a movement rotated 180 degrees to preserve the orientation and legibility of its complex functions for left-wrist operation. Despite its mechanical density—perpetual calendar with day, date, month, leap year and moonphase, plus split-seconds chronograph—the watch remains slender, underscoring Patek’s finesse in grand complication watchmaking. Water-resistant to 30m, the piece is completed by a charcoal grey calfskin strap with red stitching.

With extremely limited production and a configuration seldom seen in haute watchmaking, the 5373P-001 is more than a complication showcase – it is a niche collector’s grail that discreetly reframes tradition.
