The Dugena 2217 watch movement is part of the first gents automatic-family with a ball-bearing rotor. It was produced between the years 1949 and 1950. During this period, there were several variations due to the change from T- to U-shock device and modifications in the calibre. Not all calibres were made in the TC variant. The known versions include the UT and UC, with some models having a detached manual wind function. The movement offers automatic winding and features a sweep second hand.
