The Patek Philippe Grand Complications reference 5373P-001 is a distinguished 38.3mm luxury timepiece crafted from 950 platinum, notable for being the first “destro” or left-handed chronograph in the brand’s recent history. This model features a charcoal grey dial with a vertical satin finish and a black-gradient rim, protected by a slightly domed sapphire crystal. The platinum case is characterized by a polished concave bezel and satin-finished recessed flanks, including a signature brilliant-cut diamond set into the caseband at the 12 o’clock position. It is paired with a black calfskin leather strap featuring an embossed textile pattern and red contrast stitching, secured by a platinum fold-over clasp.
Mechanically, the watch is powered by the manual-winding caliber CHR 27-525 PS Q, which holds the distinction of being the thinnest split-seconds chronograph movement with a perpetual calendar ever produced by the manufacture at just 7.3mm in height. The complex movement consists of 476 parts and provides a power reserve of up to 48 hours when the chronograph is disengaged. The “destro” configuration inverts the traditional layout, placing the crown with its integrated chronograph monopusher at 9 o’clock and the split-seconds pusher at 8 o’clock. The dial layout is also rotated 180 degrees, featuring the date at 12 o’clock, small seconds at 3 o’clock, moon phases at 6 o’clock, and a 60-minute counter at 9 o’clock, alongside apertures for the day, month, and leap year cycle.
General reviews of the 5373P-001 often highlight its impressive technical achievement and the rarity of its left-handed orientation, which appeals strongly to niche collectors. The sporty aesthetic, driven by the red varnished hands and textile-textured strap, is frequently contrasted with the more conservative design of its predecessor, the 5372P. While enthusiasts praise the movement’s exquisite finishing—visible through an interchangeable sapphire crystal case back—some critics find the bold color accents and modern dial elements a departure from Patek Philippe’s traditional elegance. Despite these stylistic debates, the watch is widely recognized as a pinnacle of horological complexity and a significant statement piece within the Grand Complications family.
