Historical Context

During the 1970s, Piaget was among the very few watchmakers capable of combining high watchmaking with avant-garde jewelry design. Hardstone dials — such as tiger’s eye — represent one of the most iconic expressions of this era. Reference 9150, featuring a rectangular “Tank” yellow gold case paired with a natural stone dial, is today extremely rare and highly sought after. A watch that perfectly embodies Piaget’s aesthetic: elegant, bold, and timeless.
