Keep these three informations in mind: 1957 – 9P – 2mm. Three informations that sum up an immense technical achievement and define an icon of the watchmaking industry: the Altiplano. If we had to summarize Piaget to one single fact, it would inevitably be “ultra-thin” watches – even if this would clearly be a disappointing shortcut. Since 1957, Piaget is one of the best, if not the most significant representative of the ultra-thin concept, a story that started with the calibre 9P and its 2mm height (and now, you know why these three informations are so important). To celebrate 60 years of ultra-thin watchmaking, here is the Piaget Altiplano 60th Anniversary Collection, to be introduced at the SIH 2017.
