This is Piaget at its absolute best.
Known for producing some of the finest ultra thin dress watches ever made, Piaget built its reputation on refinement, proportion and dial artistry. This Protocole Ref. 9154 captures all of that in one piece.
The first thing that stands out is the dial and case integration. Both are finished in matching 18K yellow gold with a vertical tapestry texture, creating a seamless, almost architectural design. The light plays across the surface beautifully, giving the watch depth while maintaining a clean, minimalist feel.
The square Protocole case adds another layer of character. At 25mm by 28mm, it sits perfectly on the wrist, offering presence without excess. The sharp edges and defined lines give it a strong identity, while still remaining elegant and understated.
Inside sits the Piaget calibre 9P manual wind movement, one of the most important ultra thin movements ever produced. This movement was a defining moment for Piaget and remains a benchmark for slim watchmaking. It allows the case to remain incredibly thin while still offering reliability and refinement.
This is not a loud watch. It does not need to be. It is all about detail, proportion and execution.

Why Buy This Watch
Piaget dress watches sit in a category of their own.
They are not about complication or size. They are about execution. The way a case is finished, the way a dial catches the light, and the way a watch sits on the wrist.
This Protocole delivers on all of those fronts. Solid gold case and dial, ultra thin movement and a design that feels both vintage and timeless.
This watch is sold as watch only, which is typical for vintage timepieces. We prioritise condition, originality and overall integrity over the presence of box and papers. All purchases are supplied with bespoke Watts On Watches packaging, full documentation and a 12 month warranty as standard.
A refined and beautifully executed Piaget that showcases exactly why the brand is so respected among collectors.
