Europa Star World first reported the prototype of constant-force escapement published by Girard-Perregaux five years ago. After five years of research and development (coinciding with the 2013 Baselworld World Watch and Jewellery Show), the brand now introduces the first watch equipped with this innovative escapement.
Girard-Perregaux Nicolas Dehon, manager of Girard-Perregaux’s R & D department, travelled by train one day, in which he was playing with tickets at will. He bent this small piece of paper in his fingers, and suddenly, an idea to invent an escapement broke into his brain. The elastic silicon crystal spring of this new system can alternately press the pressure one by one. Passing it on is like a ticket that bends in one direction and then in the other direction. The basic operating principle of Girard-Perregaux constant power escapement system: the heart of the constant power escapement system is an elastic silicon crystal hairspring that is 6 times younger than human hair. The secondary wave vibration releases a small amount of energy. This energy is stored in the spring of the escapement, which makes him bend from the steady state to the metastable state. At this time, he has higher energy than the steady state, and then swings back and forth to the swing The wheel provides stable and average power, keeping the balance’s swing amplitude and vibration frequency stable until the power reserve of the barrel is exhausted-in fact, more than a week, because it is a double barrel, each contains two springs .

The main difference between the first proposed concept and the finished escapement series is that the double escapement wheels each contain three instead of six wheels, which is equivalent to a movement of 3 Hz (21,600 vibrations per hour) ). The escapement has applied for two technology patents, one is a ‘metal piece’ (spring), which was filed in 2008, and the other is a limit brake used in a flexible system.

The first constant-power escapement watch combines cutting-edge technological achievements and time-honored design. The dial layout focuses on the butterfly-wing frame of the constant-power escapement system and the structure of an elastic spring. On the stage where the vertical system was unveiled, the new arrangement of Girard-Perregaux’s classic three bridge plywood can be seen through the anti-glare crystal glass.
The hour dial is moved to 12 o’clock, with two barrels on the left and right, which can ensure a week’s power reserve. At 9 o’clock there is a linear power reserve display. The 18K white gold case has beautiful lines and a black alligator leather strap.
