In 2019, Patek Philippe once again pushed the boundaries of contemporary watchmaking with the release of the first sports luxury grand complication, the reference 5520P Alarm Travel Time. Five years in the making and engineered with four new patent applications, this entirely new integrated movement—combination of the dual time zone and an alarm mechanism— is adorned with the Patek Philippe Seal – certifying the highest level of finishing and precision. The high-performance caliber AL 20-660 S C FUS is composed of 574 parts, with a power reserve of 52 hours.

Designed for the modern-day traveler, the alarm mechanism of this timepiece is truly unique. Operated by the interlock pusher at 2 o’clock decorated with a small bell-shaped design, it triggers a hammer which strikes a gong that encircles the movement, chiming in pleasing, gentle notes - similar to the striking sounds of a minute repeater. The function is intuitive and easy to operate, the inclusion of the small bell-shaped aperture below the 12 o’clock marker provides a convenient visual indicator of whether the alarm has been set on (white) or off (black). Directly below is a digital display of the set alarm time, which can be adjusted in 15-minutes increments, with its own day/night indicator just beneath the apertures. The classiness of its chimes is without doubt an elegant reminder in any meeting without significant disruption.

The 5520P is the very first timepiece with a water-resistant complication alarm and gong striking function fused into one. An intriguing and impressively complicated timepiece, Phillips is proud to offer the present 5520P with its original accessories in outstanding overall condition.
