Girard-perregaux’s new Con­stant Escapement L.M. model fea­tures a de­sign that is more tech­ni­cal and con­tem­po­rary. The ini­tials “L.M.” stand for Luigi Ma­caluso (1948-2010), who was the pres­i­dent of the Sowind Group own­ing the brand and the one who de­cided to trust and pro­mote this move­ment. Pro­tected by four in­ven­tion patents, the new Con­stant Escapement L.M. fea­tures a but­ter­fly-wing frame placed be­tween the lever and the bal­ance spring. This in­ter­me­di­ate de­vice serves to sup­port a buck­led­blade mea­sur­ing just 14 mi­crons thick – six times finer than a hu­man hair. With two dou­ble bar­rels, com­pris­ing springs amount­ing to a to­tal three me­tres in length, en­sure an ex­cep­tional one-week power re­serve dis­played on a lin­ear in­di­ca­tor at 9 o’clock. Hours and min­utes are read off on an off­set counter at 12 o’clock. To en­sure an un­ob­structed view of this mech­a­nism, only the sec­onds hand re­mains cen­trally fit­ted. The GP09100 move­ment beats at a fre­quency of 3 Hz (21,600 vph). The im­pos­ing 46 mm-di­am­e­ter x 14.84 mm-thick­ness case is wa­ter-re­sis­tant to 30 me­tres.
