The fruit of more than five years of R&D, the first constant-force escapement can be credited to Girard Perregaux, which radicalised technical and aesthetic options by presenting its big new innovation \u2013 the Constant Escapement<\/strong> \u2013 at Baselworld.

It is a reminder that a Manufacture is not something that is improvised and that GP belongs to that circle of great brands whose integrated production possesses authentic innovative ability. A guarantee of precision and regularity for the functioning of a mechanical watch, the constant-force escapement allows continual energy to be passed on to the regulator (balance), whatever that of the barrel. Behind a relatively simple principle lie three patents as well as a demand for absolute precision.
\nThus, a 14 micron silicon-buckled blade which is part of the intermediate device integrated within the new escapement, stores up energy to a certain threshold verging on instability, which remains identical, and is then passed on entirely and instantly. The role of the micro-accumulator enables it to compensate for the variable energy of the barrel by releasing the same amount of energy each time. Contrary to certain mechanisms in which the constant force is supplied over an average, this is an authentic constant-force escapement, as the latter is indeed instantaneous and continuous. The twin patented barrels, of which the cover and ratchet are made all of a piece and of which each drum contains two stacked series of springs, ensure seven days of autonomy displayed in linear mode at 3 o\u2019clock. To provide maximum visibility of the lower part of the dial to the escapement, its butterfly wing-shaped frame and it blade vibrating along its central axis, the hours and minutes use a disc covering part of the barrels. Entirely exposed on the back of the white gold case, the unusual calibre representing a genuine \u2018chronometric\u2019 or precision-timing breakthrough reveals an atypical architecture that is immediately identifiable with the constant escapement.
