Jaeger-LeCoultre Master Control

The Master Control is Jaeger-LeCoultre's statement of quiet competence. Every watch in the line passes the maison's 1000 Hours Control, a six-week testing protocol covering running precision, water resistance and shock in cased-up condition rather than movement alone — a standard the industry does not require and few match. The dial is a study in restraint: applied indexes, a sector minute track, dauphine hands. The manufacture calibre is made entirely in the Vallée de Joux.
