ROCK IT

Both jewellery and watch, the jaeger-lecoultre Joaillerie

101 Feuille in pink gold is smothered in 10.3ct of baguette

and brilliant-cut diamonds, with time concealed by a diamond

set 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.
