Piaget Protocole 91541 – 18k Yellow Gold, 1980s - Geometric elegance meets Piaget’s golden age of design.
The Piaget Protocole Ref. 91541 embodies the refined architectural spirit that defined Piaget’s creations of the 1970s and 80s — watches that blurred the line between jewelry and horology.
This interpretation of the Protocole captivates at first sight: a geometric 18k yellow gold case seamlessly integrated with its matching gold bracelet, forming a unified design language of clean lines and sculptural proportion. The golden dial, subtly mirroring the bracelet texture, brings harmony and sophistication in a way only Piaget could achieve.
Powered by the ultra-thin hand-wound Caliber 9P2, this masterpiece exemplifies Piaget’s pioneering work in creating the world’s slimmest mechanical movements. Delicate, precise, and impossibly elegant — this Protocole represents pure 1980s luxury.
