- Roamer automatic watch 1933
In 1933, Roamer patented [1] an automatic pendulum winding system: a small weight fixed by a pin to one side of the case moves with the wrist and winds the movement. This solution had no future for the Solothurn manufacturer, which remained faithful to hand-wound calibers until the early 1950s.
- waterproof keyless watches
Based on patents by the famous engineer Ernest Morf [2], Roamer keyless waterproof watches were a great success from 1941 onwards.
No tools were needed to open or close the case.
