The Unitas 6311 is a mechanical watch movement with a unique design where the train and hand gear are separately driven by the barrel. This allows for a lower profile and ample space for a large balance wheel. However, it necessitates high precision and gear stability due to the numerous wheels involved in coupling the second- and minute hand. The movement offers functions such as manual winding, sweep seconds, quickset date, shock protection, and a calendar with quickset. It was commonly used around 1980.
The Unitas 6311 features the following functions:
- Calendar with quickset
- Date: quickset
- Manual Winding
- Shock Protection
- Sweep second
