The Unitas 6305 watch movement, manufactured around 1970, features a manual winding system and a sweep second function. Noteworthily, it utilizes a pin lever mechanism and exhibits a unique arrangement where the train and hand gear are driven separately by the barrel. In certain late samples, the hairspring terminal is glued, and the stem mechanism operates without a setting-lever spring.
The Unitas 6305 features the following functions:
- Manual Winding
- Pin lever
- Sweep second
