Notice the lavender-hued mechanism shaped somewhat like a pair of moth wings? It’s a silicium blade, one of the most exciting modern horological inventions as it delivers constant force to ensure that the regulating rate does not fluctuate, thus offering superlative precision. The conventional barrel spring delivers diminishing force as it gradually unwinds; the silicium blade resolves this problem by ensuring that the amplitude of the balance remains uniform regardless of the amount of energy left in the barrel.

Six times thinner than human hair, it serves as a regulating organ between two escape wheels for extraordinary rate stability and chronometric performance, which is COSC-certified. This technical breakthrough was first introduced by Girard-Perregaux in a concept watch in 2008 before appearing in a production version, the Constant Escapement L.M., in 2013. The timepiece would go on to win the Aiguille d'Or at the GPHG.
