The Dugena 1025 watch movement, produced between 1950 and 1954, was a notable advancement in gents automatic-family movements, featuring a ball-bearing rotor. This movement underwent several modifications, including a transition from T- to U-type shock devices and a modified calibre. It should be noted that the availability of the TC variant for all calibres remains uncertain, as only the known variants are listed. Additionally, the 1247UC movement includes a detached manual wind and functions include automatic winding and a sweep second hand.
