The Master Grande Tradition Quantième Perpétuel 8 jours SQ watch demonstrates all Jaeger-LeCoultre's mastery of Rare Crafts such as skeletonising, engraving and enamelling. This watch's skeleton movement is cut away and decorated entirely by hand. In order to enhance the dial, its rim is decorated with guilloché work and covered with translucent enamel. A truly exceptional timepiece, it is also the only perpetual calendar watch with an 8-day power reserve. Its perpetual calendar functions are mechanically programmed until the year 2100, and are all activated by a single date-corrector.
Reference 5063540 was introduced at SIHH 2016. It features a green enameled outer ring on its dial.
