Piaget was a pioneer in the history of ultra-thin movements,
with its famous Caliber 9P hand-wound movement and Caliber 12P
automatic movement. Each of these pieces was the thinnest in its
category worldwide at the time of its launch, respectively in
1957 and 1960. This legacy led to modern movements such as the
430P, 450P and 438P, with a depth of just 2.1 millimeters. The
exacting field of ultra-thin calibers requires an extreme level
of expertise to push the components to the limits of their
capacity and ensure fine adjustment. When it comes to combining
