Patek Philippe Grand Complications 5520

Patek Philippe Grand Complications 5520RG-001 has a 42.2 mm case in rose and white gold, a GMT watch built on Travel Time and alarm functions. The case is 11.6 mm thick and the dial sits under a sapphire crystal, with an interchangeable solid or sapphire caseback on view. The self-winding calibre AL 30-660 S C FUS offers 42 hours of power reserve, along with central seconds and date. The alarm strikes a classic gong on a 24-hour display, paired with Travel Time indexed to the local hour. Hands and numerals carry luminous treatment. A calf leather strap closes with a rose gold pin buckle. Patek Philippe rates the case to 30 metres, notable for a chiming watch.
