Patek Philippe Grand Complications5520P-001, Platinum, Black Dial, 42 mm

Patek Philippe 5520P unveils an innovative self-winding grand complication that seamlessly merges its exclusive dual time zone "Travel Time" system with a 24-hour alarm mechanism featuring a classic gong and hammer. Fueled by a self-winding mechanical movement, the watch houses the remarkable Caliber AL 30‑660 S C FUS. The 24-hour alarm, resonating with a chime on a classic gong, finds its place in a dedicated aperture. Additional features include alarm on/off indication and day/night indication for both the alarm and local time in designated apertures. The watch also adeptly displays two time zones: local and home time, each accompanied by a separate day/night indication in dedicated apertures. A local date is thoughtfully presented by hand, and a sweep seconds hand completes the meticulously crafted ensemble. Exquisitely crafted in platinum, the case boasts interchangeable solid and sapphire crystal case backs. With a water resistance of up to 30 meters, the watch showcases a diameter of 42.2 mm and a height of 11.6 mm, embodying both robustness and sophistication.
