Arsenale Calendario - 6221581C

A new architecture takes shape with the introduction of the automatic calendar, a complication that allows the day, date, and month to be read at a glance. The dial is constructed on multiple levels: symmetrical subdials, a power reserve indicator at 12 o'clock, and, at 6 o'clock, the 24-hour display is reinterpreted through a day-night disc defined by a sapphire crescent secured by two screws. This unconventional construction solution introduces depth and order while maintaining immediate readability.
