Piaget Protocole 927 18k White Gold 1970s

The Ultra-Thin Icon — Where minimalism meets masterful precision.

At just 2mm thick, Piaget’s Caliber 9P changed the landscape of watchmaking in 1957 — enabling cases to be elegant, sleek, and artistically expressive. The Piaget Protocole Ref. 927 embodies that philosophy with its flawless silver sunburst dial, geometric case lines, and architectural bezel detailing.

Crafted entirely from 18k white gold, the watch features a clean rectangular profile with a beautifully textured bezel that catches light from every angle. Its minimalist layout allows the refined craftsmanship to take center stage — classic Piaget at its most tasteful.

Paired with the original black Piaget leather strap and matching 18k white gold buckle, this piece offers a complete, original package. The manually wound Cal. 9P1 inside remains a mechanical feat — here professionally serviced and running strong.

Understated but striking, the Protocole is a true Piaget signature — refined, architectural, and impossibly thin.
