This new chronograph - with its 569 parts probably the most complex ever made - incorporates the latest fruits of research carried out by the Manufacture. The Jaeger-LeCoultre Calibre 780 chronograph is operated by a column wheel with the start and stop precision of the timing controlled by a vertical coupling. All parts of the movement are finely decorated.
