The Patek Philippe masterpiece features the manually wound Caliber CHR 27-525 PS Q, split-seconds monopusher chronograph renowned for its precision and elegance. This exquisite timepiece offers a 60-minute counter and a perpetual calendar with day, month, leap year, and day/night indications in apertures. The date is elegantly indicated by hand, while the moon phases and small seconds add to its complex functionality. The dial, striking charcoal gray with a black-gradient rim and vertical satin finish, showcases gold-applied numerals on an 18K gold plate, reflecting a sophisticated yet bold design. Encased in lustrous platinum, with a diameter of 38.3 mm and a height of 12.93 mm, this watch is water-resistant up to 30 meters. It features interchangeable solid and sapphire crystal case backs for versatility. The strap, crafted from black calfskin with an embossed fabric pattern, is secured with a fold-over clasp, providing refined and comfortable wear.
