Master Grande Tradition Grande Complication

Jaeger-LeCoultre 2015

ref. Q502 25 80
Men's

Alongside its traditional hands, this Grande Complication model dedicated to astronomy is distinguished by the sky chart of the northern hemisphere depicted on a rotating dial, along with an orbital tourbillon secured to the dial and a clockwise-turning sun-shaped cursor. This exceptional creation is further enhanced by a minute repeater chiming with a rich and intense tone thanks to the cathedral-type crystal gong and trebuchet hammers developed by the Manufacture Jaeger-LeCoultre. The striking mechanism is also equipped with a more ergonomic, smooth-handling repeater slide
