The Marvin 744 watch movement, produced from 1957 to 1962, was part of the first movement family to feature a micro rotor for self-winding. It utilized a unique self-winding gear system, employing a pinion floating between two large jewels to switch direction. In certain 17-jewels variants, one of these jewels was substituted by a polished steel disc. Not much is known about the differences between the 663 and 666 variations. The movement featured automatic winding and a sweep second function.
The Marvin 744 features the following functions:
- Automatic Winding
