The Unitas 6325 is a manual-wind chronograph movement with a 60-second and 30-minute counter, utilizing a cam switching system. It features a sub-second function and provides day and month displays that can be set using a pusher located at 10 o'clock. The day can be adjusted by pushing deeper, while the month requires manual adjustment. Additionally, the movement includes a date hand and a moon phase indicator, which can be set using a pusher located at 8 o'clock. Deeper pushing is required to adjust the moon phase. The Unitas 6325 is capable of both chronograph and calendar functionalities. This movement was commonly used around the 1950s.
