The Aurore 4207 watch movement is a manual wind movement that features a sweep second function. It is similar to the 231 movement in terms of design but potentially has a thinner hand-gear plate due to the sweep second post not protruding out of the cannon pinion. This movement was commonly used around the period of 1950.
The Aurore 4207 features the following functions:
- Manual Winding
- Sweep second
