New Constant Escapement by Girard-Perregaux
Swiss watch brand Girard-Perregaux has presented the first regular model based on the conceptual framework of the constant-force escapement accessible in 2008.

The innovation development is that the escapement, sending a continuous stream of the winding barrel energy on the mechanism of hands’ rotation and gear, governs the balance spiral of the watch, it is very important the isochronous of the spring oscillations, providing uniformity of its work.

Constant escapement – these are energy pulses of equal magnitude reported by the balance wheel, regardless of the voltage winding spring. To achieve this result, the escapement mechanism is integrated into very thin plate, accumulating daily energy up to a certain extent, which borders with its unstable level, and then at the same time it gives it - and so on to infinity. A silicon plate, used in this mechanism, 6 times thinner than a human hair.
The plate is fixed to as close to her as unstable position. So, to move into a different position it is enough quite a bit of energy, which the balance wheel gives. When the plate changes the position, it pushes the balance wheel, while it is balanced by the difference in the flow of energy from the winding barrel and released each time the same amount of energy. Constancy of its work is certified by laboratory tests.

Carrying a frequency of 3 Hz or 21 600 pc / h. The caliber MVT-009 100-0007 provides a 7-day power reserve.

The innovative mechanism is enclosed in a round case with a diameter of 48 mm white gold, made in the characteristic Girard-Perregaux’s style. The model’s dial is presented with slots to observe the work of the escapement and two winding barrels, which are on both side of an additional dial, on which is carried out the indication of hours and minutes. The constant escapement module is secured by three bridges. The novelty comes on an elegant alligator leather strap in black with a white gold buckle.
