The Dugena 1021 watch movement, developed in 1955, is a detached manual wind movement with wheels made of beryllium bronze. The family of movements, although produced for a relatively short period, consisted of two variants of the manual wind gear and two balances, suggesting an experimental nature. The movement features various functions, including automatic winding, sweep seconds, date display, and a calendar. It was predominantly used during the approximate period of 1955.
