Here’s how Spring my time wristwatch Drive works. The mainspring of a Spring Drive watch drives a standard gear train. At the end of the gear train, there is a small disk – the Spring Drive glide wheel. At the center of the glide wheel is a small permanent magnet, which turns in between two tiny electromagnets connected to wire-wrapped festina watch coils; the glide wheel acts as the rotor of an electrical generator.
