The energy regulatory system is used on the dial clearly in scene
Today is a little bit technically – and extremely exciting. As with the constant escapement system Girard-Perregaux presented a real revolution of Haute Horlogerie. When the first prototypes of the technological revolution, have been shown some time ago, all experts were impressed and amazed. Now comes the mechanical innovation for the first time at the factory of a new clock to use – and not in a limited edition, but in a production model. Five years of research and development in a new area it has needed to make this design reliable.
To understand the relevance of the system, you should pick out a little:
The heart of a mechanical watch is the regulating body, the balance. It regulates the energy flow from the barrel to the gear train and ultimately also the speed of the pointer movements. The most important aspect is it but not so much the speed of this heartbeat, so the selected frequency, but the regularity of the movement. This is like a dance and can be three or four times in a given time – or even a thousand times. The most important thing is to maintain this rhythm itself over time steadily.
Replacement for Swiss lever escapement
The Swiss lever escapement has prevailed in the mechanism as a regular clock as default. Unfortunately, this system has a flaw: it can pass only the energy that comes from the barrel – and this decreases with time. Here, the new system of Girard-Perregaux provides relief. It ensures a constant force the balance evenly energy supplies regardless of the energy that comes from the barrel. To achieve this, an additional element was incorporated into the inhibition, consisting of extremely thin, central component. This strip stores energy up to his limit to the instability. The full stored energy is then emitted immediately before the same procedure starts again from the beginning.
The fine Silicon springs provide a steady energy supply of the balance
The function this system demonstrates an experiment: take a train ticket vertically between your thumb and index finger. Now, turn it to a “C” or an open parenthesis to form. Does it now from the side pressure on the material on, you feel a resistance – up to the moment in which the ticket on the other side shoots up and reflects the preceding form. This phenomenon is known as kink instability, which one describes the transition from one phase of compression to a curved State. Experts speak of a buckling under compression force. The system of Girard-Perregaux, the thin strips composed of silicon, is just as fine as the one-sixth of a hair. However, it has the function of a mini energy storage device. The system is in duplicate, to balance out the forces in the middle of the balance wheel tire. Thus at this point to avoid an excessive stress and ensure free movement.
The complete movement was designed for a power reserve of several days – with a linear power reserve indicator on the dial, which shows the effectiveness of the new suspension with long maturities. For this, the plant draws power from two parallel barrels.
Technical optics for the first production model
Two barrels provide a power reserve of about a week
The unique movement with his original and innovative inhibition will be used by a housing in scene of technology recognizes the achievements without too intrusive in the foreground make them.
Therefore, the first clock equipped with this system has a distinctly technical and contemporary design. At the same time, the model refers to the typical design language of Girard-Perregaux and the creative tradition of the House. The movement takes place in a round, gently domed white gold case with a diameter of 48 mm.
Inhibition reminiscent of their appearance the wing a butterfly with a vibrating Strip as a central axis. She will skilfully set. Hours and minutes are read from a remote dial at 12 o’clock, flanked by the two energy storage, the two barrels. The linear designed power reserve indicator stands at 9 o’clock. The entire lower part of the clock is the system of the constant escapement in the center that attracts everyone’s attention. Beneath the anti-reflective Sapphire Crystal are also the three bridges, Girard-Perregaux is known for its design and which play an important role in this arrangement.
