Jaeger-LeCoultre pairs its miniature Calibre 101 with a new bangle

Inspired by a 1955 Duoplan design, the new watch alternates black HyCeram with diamond-set bands around a sculptural bracelet. Its Calibre 101 retains the tiny two-level architecture associated with the movement introduced in 1929.

The movement measures 14 by 4.8 by 3.4 millimetres. The launch applies established mechanical miniaturization to a new exterior rather than introducing a newly invented calibre.
