Piaget, a leader in ultra-thin watchmaking, has been pushing the boundaries of precision and design since 1874. Known for innovations like the Calibre 9P in 1957 and the Calibre 12P—the thinnest automatic movement in the world at just 2.3mm—Piaget has cemented its place in horological history. The brand’s fusion of technical mastery and elegant jewelry design has made their timepieces iconic, from wristwatches to creative hidden watches in brooches and cufflinks.

Today, Piaget continues to lead in ultra-thin watchmaking with models like the Altiplano Ultimate, which at 2mm, holds the title of the thinnest watch on Earth. Discover our collection of vintage and preowned Piaget watches below, where groundbreaking design meets timeless style.
