Piaget, the master of thin watches since 1957, first used its “fusion concept” – to make watches thinner – in the 900P in 2014. At just 3.65mm, it was the world’s thinnest mechanical watch at that time. In 2018, Piaget launched the Altiplano Ultimate Automatic which, at just 4.3mm thick, became the world’s thinnest gold watch. At that year’s SIHH, Piaget stole the show when it unveiled the remarkable Altiplano Ultimate Concept – the world’s thinnest mechanical watch. At this year’s W&W, Piaget unveiled the production version of the watch.
Altiplano Ultimate Concept
It measures just 2mm thick – that is the same height as two credit cards stacked together. The development of this watch served as a stage for numerous Piaget innovations, including a case that formed part of the movement, a unique integrated winding crown, an ultra-thin (0.2mm) crystal and, more importantly, new constructions for the barrel and energy regulation. The power reserve has been extended to more than 40 hours, a benchmark among ultra-thin watches.
