At the SIHH 2018, Piaget unveiled the Altiplano Ultimate Concept, the thinnest mechanical watch in the world. Two years later, Piaget presents the same watch as a regular production watch that you can now finally get to own. You can see our live pictures of the concept watch in this feature. Measuring 2 mm in thinness, the new Piaget Altiplano Ultimate Concept 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 crystal and, more importantly, new constructions for the barrel and energy regulation.
