Pushing the boundaries of Haute Horlogerie now comes the new Piaget Altiplano Ultimate Concept Tourbillon. Its dimensions, which truly stretch the limits of watchmaking feasibility, with a diameter of 41.5 mm and a thickness of only 2 mm, make it the thinnest tourbillon watch on the market. The blue PVD-treated cobalt alloy case is water resistant to 20 meters and the watch is simply unreal. A glorious way to celebrate 150 years of history at Piaget.
