The Eterna 1246UT watch movement, used from 1970 onwards, features Diafix combined settings for the escape wheel and third wheel. Unlike typical manual-wind calibres, the winding gear is integrated into the movement itself. This integration, along with the indirectly driven minute hand, contributes to a sturdy movement design with a relatively large balance and low profile. Additionally, the Eterna 1246UT movement includes automatic winding, a sweep second hand, a hack feature, and a micro adjustable regulator.
The Eterna 1246UT features the following functions:
- Automatic Winding
- Hack feature
- Micro Adjustable Regulator
- Sweep second
