Girard-Perregaux’s Constant Escapement L.M. debuted in 2013, marking one of the brand’s most exciting innovations in its history. As the culmination of several years of research and development, it was the very first constant force escapement to be successfully placed in a wristwatch. The feat is an advanced and sophisticated solution to a quest that has perplexed clockmakers and watchmakers since the beginning of time, constant force – as such it is a victory over decreasing power in traditional mechanical watches to achieve greater precision and regularity.

To accomplish this, Girard-Perregaux watch masters have integrated an intermediate device into the escapement, consisting of an extremely thin silicon blade that stores the energy up to an invariable threshold bordering on instability, and then transmits it all instantaneously, before recommencing the cycle. 

This groundbreaking timepiece is now available in a pink gold case with a softly domed, varnished white dial that exudes timelessness and elegance in every respect. The warm hue of the 18K pink gold version compliments the traditional architecture and intricacies within this masterpiece of watch mechanics. The faceted Dauphine hands and applied hour markers have also been redesigned in the same spirit and color. Despite its 48 mm diameter, the sleek case with softly curved lugs gently hugs the wrist for perfect comfort.

The Constant Escapement L.M. with the new pink gold case is worn on a matte black alligator strap with pink gold folding buckle.
