The Harmonious Oscillator

 

Mika Rissanen, a watchmaker specialising in grand complications working for the Rudis Sylva brand, is the brains behind this patented invention.

 

The technical specifications are as follows:

  • Two complete toothed balances are interlinked. This combination ensures the same amplitude.
  • The symmetry and energy of the balance springs are constantly opposed, enabling instantaneous average correction in the vertical position, which eliminates the effect of gravity.
  • Frequency: 21,600 vibrations/hour (3 Hz)
  • The cage turns 360 degrees in 60 seconds
  • Cage diameter: 17.40 mm
  • 2 flat balance springs, asymmetric deployment
  • 2 specifically shaped toothed balances made from special material
  • 1 escapement with 1 lever positioned at 90 degrees
  • Manual winding mechanism
  • Power reserve: around 70 hours
