Built around the smallest mechanical movement ever made, developed in 1929 by miniaturising Jaeger's own Duoplan calibre and still holding that record nearly a century later: 14 x 4.8mm, 3.4mm thick, under a gram, in 98 parts. Queen Elizabeth II owned one — a coronation gift from the French president, worn as a bracelet watch with the dial concealed inside a diamond-set cuff — and Jaeger-LeCoultre made her a special edition to mark her Diamond Jubilee in 2012.
Key dates.
- Calibre 101 introduced as a miniaturisation of the 1924 Duoplan movement

How do I check a Jaeger-LeCoultre Q2873220 with Watch Safe?
Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
