The Dugena 3310 is a manual-wind chronograph watch movement with functions including a 60-second, 30-minute, and 12-hour chronograph, sub second display, day indicator, date hand set by a pusher at 8 o'clock, and month indicator set by a pusher at 10 o'clock. The movement is equipped with a pillar wheel system for operating the chronograph. It was introduced around 1955 and is operated manually. These functions make the Dugena 3310 movement suitable for both chronograph and calendar applications in mechanical watches.
