The famous Duoplan lever movement was one of Jaeger-LeCoultre's land mark innovations in the late 1920s. As its name suggests, it consisted of two superposed horizontal planes, designed to achieve the greatest mechanical precision while occupying the smallest amount of space possible. The positioning of the winding and hand-setting crown on the reverse of the case furthermore enabled the production of watches with a refined and elegant look.

It was generally associated with Cartier who used it for the production of the firms' "montre baguette" models, lady’s dress watches of astoundingly small size and exceptional elegance and finesse.

Queen Elizabeth II wore a Jaeger-LeCoultre wristwatch with a Duoplan movement for her coronation in 1953
