To emphasise the exceptional character of the Grande Tradition collection, this remarkable timepiece with its grandes complications is a masterful reinterpretation of the tourbillon and perpetual calendar functions. The minute repeater with its crystal gong incorporates the latest discoveries by Jaeger-LeCoultre with “trebuchet” hammers. The night sky and sidereal time add the final touches to this exceptional ensemble. With more than 500 components, its new Jaeger-LeCoultre Calibre 945 has a silicon escapement to ensure optimum running precision. This timepiece is available in a limited series of 75 in white gold.
