Piaget Protocole - Black Dial

Trade In
Details

A Study In Disciplined Design

During the late 1970s and early 1980s, Piaget established itself as a leader in creating elegant dress watches defined by precious metals and clean lines. The Protocole reference 9154 is a perfect expression of that philosophy. It avoids complexity in favor of pure form, pairing a classic tank case in solid 18K yellow gold with a minimalist, time-only black dial. This was an era when Piaget's mastery of ultra-thin movements allowed its designers the freedom to focus on proportion and material, resulting in watches that were both technically impressive and aesthetically pure.

The Purity Of Yellow Gold And Black

This example highlights one of the most timeless combinations in watchmaking. The warmth of the yellow gold case creates a sharp, confident contrast against the deep black dial, keeping the focus entirely on the core design. A signed 18K gold Piaget buckle on the strap is an important detail, preserving the piece's brand integrity and completing the look. This configuration is a testament to the idea that true luxury often lies in confident simplicity.

An Untouched Case And Honest Dial

The 18K yellow gold case is in great cosmetic condition and appears untouched. Its sharp lines and original proportions are well-preserved. The crystal is free from any scratches or marks. As is common with dials from this era, there are some small marks around the outer edge. The watch retains its original dial, crown, movement, and caseback, confirming its authenticity. As with every watch we offer, this piece has been verified as mechanically sound and is ready to wear.

Elegance Distilled To Its Core

This is a watch for someone who understands that classic design never fades. The case has a subtle but definite presence on the wrist, delivering the iconic tank silhouette without unnecessary bulk. Because it is a manual-wind watch, it asks for a moment of interaction each day. The ritual of winding the crown creates a physical connection between the owner and the machine, a small ceremony that is often lost in the modern era. It is a piece that works because it is focused, refined, and effortlessly elegant.

History

The Protocole is the formal expression of Piaget's integrated bracelet philosophy applied to a stepped rectangular case — structured, architectural, and built in 18-karat gold with ultrathin quartz or manual movements. Produced from the late 1970s through the 1990s, it bridges the gap between Piaget's pure dress watches and the sportier Polo.

References 174101 and 9150 in our inventory offer the Protocole in yellow gold, white gold, and with both original leather straps and integrated gold bracelets. The stepped case — where the case descends in layers from the crystal to the lugs — is a detail that rewards close inspection. These are watches made for the kind of person who notices such things.

What Our Clients Say About Us

I knew I was gonna like Danny, based on his name, but nothing could’ve prepared me for how great of an experience this was. He had the most beautiful 70s Seamaster Cosmic on his website and I was set to be married 2 days later - I arranged to buy it but before leaving we both realized it needed to be serviced. I panicked, because I was literally buying this for my wedding, and Danny being the legend he is, loaned me a nearly identical Seamaster to make sure I could get through the event Never have I had someone go so above and beyond for me, especially while purchasing one of the lesser priced items in their inventory. He serviced my watch and exchanged it with me after the wedding on a super fast turnaround timeline. I would sincerely recommend you visit this guy, you will not be disappointed Edit: adding a pic of the loaner (two tone) and the owner (crosshair)

Great service and shop. Danny and his team were incredibly accommodating, professional, and kind. Great selection of vintage watches. Their store is the hidden gem in the diamond district.

This was my first real luxury watch purchase, a Rolex 15200 Date 34mm, I own Tissots and a Laco, but those are entry level luxury watches. I found Danny’s Vintage Watches online, and had great feedback both on Google, Chrono24 and the Reddit watch community. So decided to give him a shot as buying online can be a crap shoot. Ordered Monday night, was at my doorstep Friday morning. Despite the watch being over 30 years old, serial number says it’s from 91, the watch looked new. Didn’t come with box or papers, and was shipped in a plastic sleeve wrapped in bubble wrap. Danny was always available to answer questions. I’ll be buying from Danny again for the next purchase…saw a couple of Speedmasters on his site I liked….
