It was within an atmosphere of extreme contrasts, between a conformist society and a small group of men and women seeking a new way of life, that the Duoplan was born. Created in 1925, this calibre made it possible to reconcile two qualities that were then thought to be incompatible, even contradictory, in watchmaking: extreme miniaturisation and great precision.

The Collectibles book is an incredible in-depth look of Jaeger-LeCoultre’s watchmaking history as it is the first time such detailed information on key 20th-century models has been brought together in a single volume. Written by the experts within La Grande Maison, it covers the period from 1925 to 1974, surveying 17 of the most significant models produced by the Manufacture. Impressively exhaustive, the book features detailed background stories as well as informative photography and historic documents from the Manufacture’s archives.
