The Dugena 2309 watch movement, manufactured around 1958, features an integrated winding gear within the movement, eliminating the need for external attachment. This design, despite its higher base movement, maintains an acceptable height for the time. Additionally, the Dugena 2309 incorporates a unique motion system for its indirect sweep second, utilizing a magnet in a bushing rather than a friction spring. This ensures a smooth and uninterrupted motion for the sweep second hand. The movement possesses automatic winding, a sweep second function, and a hack feature.
