Marking The Queen’s Diamond Jubilee, Jaeger-LeCoultre presented a 101 jewellery timepiece to Her Majesty Queen Elizabeth II, homage to the piece she wore at the time of Her Coronation 60 years ago.

The white gold watch is set with baguette diamonds and is powered by the smallest mechanical watch movement in the world, the JLC Calibre 101.

First built in 1929, the Calibre 101 is so small that its 98 tiny parts only weigh one gram and its assembly is a specialised process that only three watchmakers in the Jaeger-LeCoultre manufacture can master.

Unlike the watch The Queen wore on her Coronation Day, this model is in white gold and not yellow gold. The original was given to the Queen by the French President and its whereabouts are unknown.
