Jaeger-LeCoultre has launched a smaller version (40.5 mm) of its Duomètre à Quantième Lunaire watch.
Introduced in 2010, Jaeger-LeCoultre Duomètre à Quantième Lunaire is the second creation from the highly technical Dual-Wing concept.
The new 40.5mm diameter version (reference Q6042521) comes in a pink gold case with a silver-colored, crystalline grained dial. Its precursor has a 42mm case.
The elegant and easily readable dial displays the hours, minutes, seconds and moon-phase. Inside the JLC Duomètre à Quantième Lunaire 40.5 model beats Calibre 381, based on the Dual-Wing concept.
This manual-winding Jaeger-LeCoultre Dual-Wing movement incorporates two independent energy sources: the first, regulated by the escapement and the balance, is entirely dedicated to the precise measurement of the passing of time; whereas the second source of energy is devoted to the display of the functions: hours, minutes, seconds, calendar and moon phases for both hemispheres. Their synchronisation is ensured by the jumping seconds hand mechanism.
The JLC Duomètre à Quantième Lunaire watch offers a stunning precision with a jumping seconds hand moving in sixth of a second increments while displaying the date and the moon phase on a separate subdial.
