Double cone shock absorber
The enduring classic, recognised by the Swiss watch industry for over 80 years. Its exclusive design ensures the automatic recentring of the bushing and endstone while keeping the line of travel perpendicular to the balance staff. The pivots are therefore not subjected to any stress. By having only two contact points, the lyre spring ® maximises its active length.

Single-cone shock absorber
Fitted with a single cone to minimise its thickness, as well as a spring specifically designed to reduce its diameter as much as possible while maintaining optimal performance.

Shock absorber for economical calibres.
