Jaeger-LeCoultre Master Control Date

Every Master Control passes Jaeger-LeCoultre's 1000 Hours Control, a six-week protocol testing precision, water resistance and shock in cased-up condition rather than movement alone — a standard the industry does not require and few brands attempt. The dial is a study in restraint: applied indexes, a sector minute track, dauphine hands and a date that sits without disrupting the symmetry. The manufacture calibre is made entirely in the Vallée de Joux.
