Rudis Sylva is proud to present the RS12 Grand Art Horloger, the third generation of timepieces equipped with the Harmonious Oscillator and decorated in the most exquisite fashion.

This revolutionary regulator featuring two toothed balances is a unique invention minimising the effects of gravity while boasting highly sophisticated decorative details hand-worked by the region’s finest craftsmen. Its technical characteristics are also exceptional:

  • The two toothed balances are interlinked. This link ensures the same amplitude. The symmetry and energy of the balance springs are constantly opposed, enabling instantaneous average correction in the vertical position, which minimises the effect of gravity.

  • The cage turns 360 degrees in 60 seconds.

  • The pallet fork is positioned at 90 degrees.

  • The double barrel ensures a power reserve of 70 hours.

  • The frequency is 21,600 vibrations/hour (3 Hz).
