For over half a century, Piaget reigns within the ultra-thin world. The 9P, introduced in 1957, continues to be a reference within the the watchmaking industry niche for being one of the first ultra-thin caliber ever. Out of this date, many rivals attempted to achieve exactly the same degree of expertise: Jaeger-LeCoultre, Vacheron Constantin, among others. Actually, there is just one manufacture in a position to break Piaget’s record: Piaget itself. Please welcome the Piaget Altiplano 38mm 900P, the world’s slimest mechanical watch.
