Piaget Square 9771 Hawk's Eye 1970s

The Piaget Hawk’s Eye - Cool-toned precision, carved from stone and light.

This rare Piaget Ref. 9771 from the 1970s captures a unique harmony between technical mastery and natural beauty. At its heart lies the ultra-thin Caliber 9P, a mechanical marvel just 2 mm thick, which allowed Piaget to pioneer the integration of hard stone dials into elegant wristwatches.

Encased in a TV shaped 18k white gold case, this piece features an untouched Hawk’s Eye stone dial — a swirling, stormy blue sibling to the more common Tiger’s Eye. The result is a dial alive with movement and depth, symbolizing focus, clarity, and poise.

Slim and refined, this square case wears elegantly on the wrist, while the natural striations of the dial ensure no two examples are alike. The watch remains in superb condition and is paired with a minimalist leather strap for understated luxury.

A watch for those who appreciate quiet rarity and Piaget’s artful legacy in stone.
