The Unitas 6431 is an open face calibre watch movement that offers stem wind and set functionality, along with a sub second feature. The movement potentially includes an optional Breguet hairspring and exhibits varying bridge shapes, such as a possibly left-handed ratchet-wheel screw. There are other calibres, namely 231, 235, 239, 249, 255, 259, 265, 271, 277, 447, 449, 471, 477, and 508, whose distinctions in comparison to the Unitas 6431 remain unknown; these appear to be catalog designations associated with different bridge shapes.
The Unitas 6431 features the following functions:
- Stem wind and set
- Sub Second
