The Harmonious Oscillator, from Rudis Sylva, features a system with two mechanically interlinked balances driven by a single escapement. This technical innovation goes against watchmaking theories, which have always ruled out stress on the balances.With its innovative technicality, this design can boast a more accurate setting capacity than a conventional tourbillon, thanks in particular to the asymmetric deployment of the balance springs in all positions, hence the name “Harmonious Oscillator”. This world first with two toothed balances exhibits a resonance effect from the first oscillations. Mika Rissanen, a watchmaker specialising in grand complications working for the Rudis Sylva brand, is the brains behind this patented invention.
