The world’s smallest movement

1929

In 1929, at a time when demand for luxury objects had dwindled because of the international economic crisis, the Manufacture’s watchmakers set themselves the challenge of creating the world’s smallest watch movement. They miniaturised the Duoplan calibre to the limit. The Calibre 101 weighed barely one gram and had 74 parts. Crafted in extremely small quantities, but in continuous production, its record is still unmatched to date. For her coronation in 1953, Queen Elizabeth II of England wore a watch that used this superlative mechanism.
