Générale Ressorts was established in 1857 in Bienne, Switzerland, and is the market leading manufacturer of springs and spring barrels, both critical components of the watch movement.
The company develops high quality mainsprings, composed of completely non-magnetic materials with a high energy potential, exceptional fatigue strength and excellent corrosion resistance.
Générale Ressorts has filed patents for BIOFLEX®, an innovative material used for mainsprings. BIOFLEX® is a unique, patented alloy which:
- Reduces energy loss between 0 and 24 hours to increase chronometric stability
- Increases the spring's fatigue strength
- Increases the number of turns, and thereby the power reserve
