Balances toothed, connected, providing the same amplitude
Escapement just 1 with 1 pallet fork positioned at 90 degrees
Frequency 21,600 vibrations/hour (3 Hz)
Cage rotation 360 degrees in 60 seconds
Cage diameter 17.40 mm
Balance-springs 2, flat, asymmetric deployment
Balance-spring symmetry and energy constantly opposed,
Vertical gravity correction instantaneous, completely eliminating the effect of gravity
Why is the Harmonious Oscillator more accurate than all existing Tourbillons?
As a general rule, provided that it is in a totally stable situation, a Tourbillon takes a minute to compensate for the effects of gravity when in the vertical position.
The Harmonious Oscillator, by virtue of the interconnection of the balances and the asymmetric deployment of the balance-springs, enables instantaneous correction. So it is never influenced by the Earth's gravity.
The Harmonious Oscillator provides accuracy far superior to conventional Tourbillons or Karrusels.
This mechanism is close to perfection in terms of setting. The tests performed on various measurement devices give exceptional results, especially for amplitude, in all positions or after 24 hours in the vertical position.
The measured Δ amplitude are also excellent (difference in degrees amplitude upon position changes).
A number of Master Watchmakers, upon discovering this watchmaking revolution, have declared that there had not been such an important invention since Abraham Breguet's Tourbillon in 1801.
