Girard-Perregaux At the GPHG 2013

The Constant Escapement watch is taking part in the Grand Prix de l'Horlogerie de Genève competition in the Innovation category.

Girard-Perregaux has only submitted one watch to the GPHG 2013 competition: the Constant Escapement. It has successfully gone through the preselections and is now taking part in the final stage of the competition. The winners will be announced on November 15, 2013, during a prize-giving ceremony that will take place at the Grand Théâtre de Genève.
You can take part in the Prix du Public by voting for your favourite watches. To vote for the Constant Escapement, click here.

Unveiled at the beginning of 2013 by Girard Perregaux, the Constant escapement is a technical innovation which allows supplying a constant force to the movement.
The principle of a constant force escapement is that whatever the energy supplied by the barrel, the escapement returns a constant energy to the regulator (balance wheel). To achieve this, Girard-Perregaux has integrated an intermediate device into the escapement, consisting of an extremely thin blade that stores the energy up to an invariable threshold bordering on instability, and then transmits it all instantaneously, before recommencing the cycle.

The Constant Escapement watch is the first in the collection to integrate the principle of the constant escapement in its movement. The movement takes its place in a round 48 mm diameter case in white gold with a curved case band. The hours and minutes occupy a sub-dial off-centered at 12 o'clock, reserving thus the whole of the lower part of the watch for the constant escapement with its butterfly wing frame, the vibrating blade in its central axis, and the three emblematic bridges. The power reserve indicator is placed at 9 o'clock.
