In 1957, the manufacture at La Côte-aux-Fées brought out the Calibre 9P, the first ultra-thin (2 mm), hand-wound mechanical movement.

Then, in 1960, the Piaget watchmakers developed the Calibre12P, the thinnest automatic movement in the world, with a thickness of 2.3 mm (made official by an entry in the Guinness Book of Records).

In addition to coin watches, ring watches, brooch watches and cufflink watches, Piaget created their first pieces of jewellery.

In 1957, the Emperador men’s watch was launched and since its relaunch in 1999 has become one of the brand’s emblematic models.

The company’s expansion led to the opening of a new factory in Geneva, dedicated to jewellery and, in 1959, their first boutique.

In 2014, Piaget presented the Altiplano 900P. At 3.65 millimeters (around 1/8th of an inch) it is the world’s thinnest hand-wound mechanical watch.
