The Harmonious Oscillator, a standard bearer in the fight against gravity
When the Harmonious Oscillator was unveiled at Baselworld 2009, many watchmakers declared the invention to be as important as the Breguet Tourbillon created over 200 years earlier.
This horological revolution with toothed balances is the only device in the world that instantly eliminates the effect of gravity in the vertical position. The two toothed balances are interlinked. This link ensures the same amplitude. The symmetry and energy of the balance springs are in permanent opposition, enabling instantaneous average correction in the vertical position.
The Harmonious Oscillator, which is the world's number one gravity-combating device, is not only an embodiment of technical brilliance; it also appears in only the most lavish surroundings. It is always associated with rare feats of craftsmanship such as engraving, enamelling, guillochage and bevelling.
