The Calibre 101 was created in 1929 and truly showcased the know-how of the Manufacture. Its incredibly small size makes it an exceptional creation and became famous for having been worn by Queen Elizabeth II at her coronation, who received the watch as a gift from the French government.

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.
