Ultra-thin movement and jewellery
In 1957, the manufacture at La Côte-aux-Fées brought out the Calibre 9P, the first ultra-thin (2 mm), hand-wound mechanical movement.
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.
Building on the success of these ultra-thin movements, Piaget continued to innovate throughout the decades. In 2014, they introduced the Altiplano 900P, the world's thinnest mechanical hand-wound watch at just 3.65mm thick. The Altiplano 900P broke the previous record held by Jaeger-LeCoultre, incorporating the case and movement into a single unit to achieve this remarkable thinness. This watch exemplified Piaget's commitment to technical innovation and minimalist design, continuing their legacy in setting world records for ultra-thin watches.[8]
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.[9]
