Piaget 18k Onyx Square 1970s

This Piaget took our breath at first sight. These geometric forms combined with the woven 18k yellow gold bracelet, onyx dial, alpha handset and classic Piaget logo are true art.

Launched in 1957, the 9P caliber was groundbreaking for 2 reasons: standing at 2mm, it was the thinnest manual-wound movement ever made for wristwatches, and its 20.5mm diameter was much larger than the standard, therefore allowing for larger cases.

Its slimness was not only a technical accomplishment, it also allowed the manufacture to fit dials made of hard stones while retaining a thin profile like this flawless 18k Piaget with Onyx stone dial.
