A ligação entre as duras rodas de balanço garante uma mesma amplitude. Essa simetria e energia das espirais está constantemente em oposição, permitindo correcção instantânea na vertical. O sistema está dentro de uma gaiola, que roda em 60 segundos.
O duplo tambor de corda garante uma autonomia de 70 horas, num calibre automático com frequência de 3 Hz (21,600 vibrações/hora). Caixa de 44 mm, em ouro branco ou vermelho.

Seconds indicator bridge Machined from titanium and hand-bevelled, this bridge at 6 o’clock includes no fewer than 28 internal angles. It takes 10 times longer to create a sharp internal angle in titanium than a rounded corner in steel. Main plate The lower part of this strategic component features a hand-crafted guilloche decoration of tapering pyramids. From the edge to the centre of the piece, each guilloche line includes 60 pyramids, each one smaller than its neighbour, requiring extremely meticulous guilloche operations. Engraving Apparent in the marking on the double barrel bridge or the caseback sundial and inscription, the extremely precise engraving magnifies the skill of the hand-engraver whose painstaking work is carried out under microscope. Oven-fired enamel Silica stones are crushed by hand and mixed with water. The resulting material is then applied to the hand-engraved surfaces and placed in a special oven at 840°C. The resulting enamel is then polished to obtain the perfect dial.
The Harmonious Oscillator
With its innovative technical features, 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.
The Harmonious Oscillator is neither a tourbillon nor a carrousel; however they do have some aspects in common:
• Each mechanism is mounted on a rotating cage which completes a full revolution in 60 seconds.
• The system improves accuracy by counterbalancing disruption of the balance isochronism due to the Earth's gravity.
What are the major differences between the Harmonious Oscillator and a tourbillon or carrousel?
• The 3 devices have a complete balance. In the tourbillon, the balance staff is situated on the same line as the tourbillon cage pivots, whereas in the carrousel, the balance staff is eccentric. These two systems take one minute (a full revolution) to compensate for loss of accuracy in the vertical position (effect of gravity).
• The Harmonious Oscillator, by means of the interconnection of the balances and asymmetric deployment of the mainsprings, enables instantaneous time correction in the vertical position. In the same position, the tourbillon - provided it is in a totally stable position - needs a minute to correct.
In conclusion, the Harmonious Oscillator offers far better accuracy than most conventional tourbillons or carrousels. This mechanism is close to perfection in terms of time-keeping precision.
