Piaget 9127 Onyx Diamond 1970s

Glamorous Geometry in White Gold, Onyx & Diamonds — Piaget 9127

A sculptural statement in precious materials, this Piaget embodies haute horlogerie at its most artistic.

With a dial composed of natural Onyx, this timepiece is nothing short of wearable art. Crafted in 18k white gold, it features sharp geometric lines, an integrated bracelet, and Piaget’s signature Alpha hands—topped off by the iconic Piaget logo.

At its heart is the legendary ultra-thin Piaget Cal. 9P, allowing the case to remain gracefully slim even with the added complexity of a hardstone dial. Originally launched in 1957, this caliber revolutionized watchmaking with its elegant form and precision, allowing Piaget to create daring designs like this one.

Whether you admire the elegance of the diamond-set bezel, the artistry of natural stones, or the technical achievement of ultra-thin engineering, this Piaget is an unmatched treasure of the 1970s.
