Calibre 101
For over 80 years, the Calibre 101 by Jaeger-LeCoultre has remained the worlds smallest mechanical movement. This prodigious feat of miniaturisation has equipped the most exclusive watches, starting with the one worn by Queen Elizabeth II of England on her Coronation Day in 1953. The dial of the Joaillerie 101 watch is so small that time almost seems to vanish into the background so as to give pride of place to the diamonds surrounding it. Created by the skilfull hands of the worlds finest watchmakers, each Joaillerie 101 watch embodies absolute exclusivity and elegance.
