The Duomètre collection is one of our favorite collections from Jaeger-LeCoultre due to its exceptionally beautiful and highly complicated timepeices. The unique technical nature and distinctive styling of the Duomètre places it in the most exclusive echelons of watchmaking. Based on an unprecedented concept nicknamed 'Dual-Wing', its movement is composed of two separate watch mechanisms connected by a shared regulating organ. A true masterpiece of horology, the Jaeger-LeCoultre Duomètre à Quantième Lunaire ref. 6042522 is a perfect interpretation of the revolutionary ‘Dual-Wing’ concept, featuring two independent power reserves, one of which, in this case, is devoted solely to precise time measurement while the other takes care of the functional displays. Fitted with a 42 mm 18K pink gold case and a gorgeous granulated silvered dial, the Jaeger-LeCoultre Duomètre à Quantième Lunaire raises in full glory just like the moon goes from its waxing gibbous to a full moon.
