The world's smallest mechanical movement, first created in 1929. Measuring just 14mm long, 4.8mm wide, and 3.4mm thick, the Calibre 101 weighs approximately 1 gram. Despite its diminutive size, it contains 98 components. This remarkable movement has adorned the wrists of royalty including Queen Elizabeth II. Still hand-assembled today by JLC's most skilled watchmakers.
