Resistance to magnetism with Silicium

The silicon balance spring is made in an extremely clean environment in a sterile room. Its manufacture requires very high industrial skills within Swatch Group. This photolithographic process allows the same shape of the balance spring to be cloned repeatedly.

Advantages of the Silicium balance spring

  • Unaffected by magnetic fields
  • Unaffected by temperature variations
  • Resistance to oxidation
  • Resistant to aging
  • Resistant to shocks
  • Excellent shape stability (always returns to its original shape)
