The defining fact about this watch is the movement inside it. Calibre 101 was introduced in 1929 and is still the smallest mechanical movement ever put into series production — under a gram, and small enough that assembling one is done by a handful of watchmakers with the work held under magnification throughout. Elizabeth II wore a 101 to her coronation in 1953.
