Jaeger-LeCoultre, in Le Sentier, is premiering the woman’s version of a design voted Watch of the Year. Recalling 1950s styling, its «Master Lady» is equipped with the all-new high-quality seifwinding calibre 960 (20 mm across, 3.95 mm thick). Its development represented a not inconsiderable challenge : 226 parts, 31 jewels, shock-protection devices... All components including its 21K gold oscillating weight are finished and decorated by hand. Providing the hours and minutes, fitted with a centre seconds hand and a date calendar, the movement has a power reserve of 45 hours. Like every design in the Master line, each «Master Lady» is exhaustively tested for no less than 1,000 hours before being released for sale - a convincing guarantee of exceptional reliability and overall quality.
