ROCK IT

Both jewellery and watch, the jaeger-lecoultre Joaillerie 101 Feuille in pink gold is smothered in 10.3ct of baguetteand brilliant-cut diamonds, with time concealed by a diamondset leaf-shaped lid. It is driven by the world’s smallest mechanical movement, the manual-winding Jaeger-lecoultre Calibre 101 that weighs barely 1g. First introduced in 1929, the proprietary hand-assembled calibre has been updated and now comprises 98 parts — 20 more than the original — within 14mm x 4.8mm x 3.4mm, and beats at a remarkable 21,600 vibrations per hour.
