It features a perpetual calendar with various hands for day, date, and month, set by corresponding pushers at specific hours. Additionally, the moon phase can be set by a pusher at 4:30h, and the year/leap year is displayed on a disc at 9h, set with the month pusher. The movement also includes a hack feature.
