Introduced in 2019, the Patek Philippe Alarm Travel Time, reference 5520P, marked a bold and innovative addition to the brand’s Grand Complications collection. Drawing on the design codes of the beloved reference 5524G, the Calatrava Pilot Travel Time, the 5520P pays homage to early 20th-century aviation pioneers and Patek Philippe’s historic aviation watches. Its more complex sibling, the 5520P, elevated the concept to new heights, earning its place among Patek Philippe’s most exclusive offerings, available only to the brand’s most distinguished clients.

The 5520P introduced a groundbreaking 24-hour alarm complication, featuring a hammer that strikes a classic gong and a digital display for the alarm time. Powered by the newly developed caliber AL 30-660 S C FUS, the movement incorporates four patented innovations, underscoring Patek Philippe’s technical mastery.

The present example, crafted in platinum, features a striking black dial with luminous markers, evoking the vintage Pilot watches of the mid-20th century. Rare and highly coveted, the reference 5520P has only appeared at auction on a handful of occasions, making this an exceptional opportunity for collectors. Preserved in excellent condition with crisp hallmarks beneath the lugs, this timepiece is accompanied by its full suite of original accessories, including the Patek Philippe Certificate of Origin dated 2020, portfolio photograph, product literature, setting pin, presentation box, and outer packaging.
