For decades Jaeger-LeCoultre has been known as the watchmakers' watchmaker. The reason behind this is that its movements, and they have made over 1200 different calibers to date, are so good that they also supplied them to some of the greatest names in the watchworld, such as Cartier, Audemars Piguet, and Van Cleef & Arpels. One field in which they excel in particular is that of grande complications. In this, Jaeger-LeCoultre likes to challenge itself, as they did this year with the Reverso Hybris Mechanica Calibre 185.
