Jaeger-LeCoultre plunge into the Rivière

A timepiece that appears in the Guinness Book of Records is the watch containing the Calibre 101, created seventy-one years ago in 1929 by the master-watchmakers of Jaeger-LeCoultre. Weighing less than one gram, it was worn by Queen Elizabeth II at her coronation. Today, the infinitesimally small movement is now available to a wider public with the introduction of the ultimate in ladies watches - the Rivière. It has an 18 carat white gold case enhanced by 2 briolet-cut diamonds and an 18 carat white gold bracelet comprising 41 square links, each one set with a diamond (a total of 12.61 carats) and a silvered dial and leaf-style hands. There is a 98-piece hand-winding mechanical movement (3.4 mm high) with a power reserve of 33 hours.
