Audemars Piguet Calibre 2120
Calibre 2120 was introduced in 1967 as the result of a project led by Jaeger-LeCoultre, with the technical contribution of Audemars Piguet and the funding of Audemars Piguet, Patek Philippe and Vacheron Constantin, for the creation of an ultra-thin automatic movement. The joint effort produced the Jaeger-LeCoultre Calibre 920, a highly innovative and reliable movement, that each of the three funding customers renamed and customized (the Patek Philippe 28-255 C was used for the Nautilus while the Vacheron Constantin 1120 powered the 222 model).
