The Calibre 101 Q2873220 (aka: 2873220), seen from the bench

The Jaeger-LeCoultre Calibre 101 was introduced in 1929 as the world's smallest mechanical movement. It equips the manual-winding Calibre 101 with hour and minute indications. The ultra-thin rectangular case measures 14mm x 4.8mm with a thickness of only 3.4mm.
