Unworn Patek Philippe Grand Complications, 5370R-001, box and papers

The Patek Philippe Grand Complications 5370R-001 is the epitome of classical elegance paired with cutting-edge horology. Housed in a polished 18k rose gold case, this split-seconds chronograph showcases a striking Grand Feu brown and beige enamel dial with applied Breguet numerals and leaf-shaped hands in rose gold. Powered by the manually wound Caliber CHR 29-535 PS, it features a traditional architecture with a column wheel and horizontal clutch, along with a rattrapante mechanism allowing for precise measurement of intermediate times. A sapphire crystal caseback reveals the meticulously finished movement, exemplifying Patek Philippe’s dedication to mechanical mastery and timeless design.
