Upon its release in 2015, this watch became the world’s thinnest mechanical timepiece. Piaget reinterpreted its iconic Altiplano 900P, introducing a unique version at Only Watch 2015, fitted with striking red hands for the first time. By merging the hand-wound caliber with the case components, the design achieves a remarkable slenderness of just 3.65mm. This innovation draws inspiration from Piaget's very first ultra-thin movement, the caliber 9P created in 1957, and represents a crowning achievement in over half a century of expertise in ultra-thin watchmaking, a domain where Piaget excels.

Preserved in mint condition for nearly a decade, remarkably, the vibrant red hands have aged gracefully into a reddish-brown hue over the years. While the realm of ultra-thin watches has since become a competitive landscape among major watchmakers, it is Piaget that pioneered the technological innovations that continue to astound the community, showcasing their unwavering commitment to pushing the boundaries of thin watch design.
