A Onyx Stone Dial Icon — Slim, Sculptural, and Pure Piaget

Few watches embody 1970s elegance quite like this Piaget Ref. 9154 — a sleek tank-shaped creation crafted in solid 18k white gold and fitted with a natural Onyx dial that shimmers with layered depth.

Powered by the groundbreaking Caliber 9P — the thinnest manual-wound movement of its time — this watch allowed Piaget to experiment with exotic stone dials while maintaining an ultra-slim silhouette. At just 5 mm thick, it wears like refined jewelry, but with mechanical soul.

The natural onyx dial is untouched and Timeless in shape, tactile in feel, and quietly confident, this piece captures the spirit of Piaget’s golden era.
