This new interpretation of the 101 Feuille in white gold shows Jaeger-LeCoultre at its finest as a creator of women's jewellery watches. Inspiration came from a 1959 design. The beautifully curved leaf motif of this Secret watch, which shimmers with 171 diamonds, conceals the much-admired Jaeger-LeCoultre Calibre 101. Developed by the Manufacture in 1929, it remains the smallest mechanical movement in the world: its 98 components tip the scales at barely one gram.
