The Alarm Travel Time Reference 5520, known for its excellence in travel timekeeping, now debuts in an updated two-tone variant. This new version showcases a rose gold case with four white gold pusher tubes and a sunburst grey dial. This Grand Complication timepiece houses the self-winding AL 30-660 S C FUS calibre, safeguarded by four patents. It seamlessly integrates the unique Travel Time dual-time display, with the date synchronized to the local time, alongside a 24-hour alarm function that features a hammer striking a classic gong. The two Travel Time pushers and the 2 o'clock pusher, used to activate or deactivate the alarm, are equipped with a patented safety locking mechanism.
