The Patek Philippe Grand Complications Reference 5370R-001 is a technically sophisticated split-seconds chronograph that debuted in 2025. It features a 41mm case crafted from 18k rose gold, characterized by a concave bezel and recessed, satin-finished flanks. The watch is distinguished by its two-tone Grand Feu enamel dial, which utilizes a rich brown base complemented by beige champlevé enamel for the subsidiary dials and the peripheral tachymeter scale. The dial is further detailed with applied Breguet numerals in rose gold and leaf-shaped hands treated with luminescent coating.
At the heart of this timepiece is the manually wound caliber CHR 29-535 PS, an in-house movement comprising 312 parts and incorporating seven patented innovations to enhance precision and reduce wear. This movement maintains a traditional architecture with two column wheels and a horizontal clutch, offering a power reserve between 55 and 65 hours. The primary chronograph functions are managed by pushers at 2 and 4 o’clock, while the split-seconds (rattrapante) mechanism is operated via a pusher integrated into the crown. The watch is completed with a shiny dark chestnut alligator leather strap and a patented rose gold triple-blade fold-over clasp.
General reviews of the 5370R-001 often praise its “reverse panda” aesthetic and the warmth of the rose gold and brown color palette compared to previous platinum versions. Collectors highlight the exceptional depth and craftsmanship of the fired enamel dial and the visual appeal of the movement through the sapphire caseback. While its 13.56mm thickness and 41mm diameter are noted as substantial for a dressier complication, reviewers generally find the proportions balanced. Some critics have pointed out the significant price increase over previous iterations and the niche appeal of the brown-and-beige “cappuccino” color scheme.
