Piaget Protocole "Grenade" 91104 – 18K White Gold

Trade In
Details

A Rare Chromatic Execution Of The Grenade

The Grenade reference represents the pinnacle of Piaget's ability to merge sculptural form with elite gem setting. While many high jewelry pieces from this era relied on a standard diamond palette, this specific configuration incorporates pink rubies and blue sapphires into the diamond bezel. 

Diverse Stones And Artisanal Intent

The use of multiple stone types and cuts provides a level of visual depth that standard pave dials can't match. The contrast between the deep blue sapphires, the pink rubies, and the brilliant cut diamonds gives the watch a vibrant character that changes depending on the light. Because these configurations were often unique or special order, the watch carries a level of artisanal intent that is absent from mass produced jewelry watches.

Very Good Condition With Secure Setting

The case remains in very good condition, preserving the sharp and difficult angles of the original design. All stones, including the brilliant cut diamonds and the colored rubies and sapphires, are securely set and show no chips or surface wear. The pave dial is clear and vibrant. It's still paired with its original leather strap and signed 18k white gold buckle. After passing our test bench, the movement is running strong.

A Sculptural Trophy For The Serious Collector

This is a trophy piece for a collector who values scarcity and high level craftsmanship over common luxury tropes. The mix of stones gives it a visual depth and personality that standard diamond watches cannot match. It carries a significant presence on the wrist that feels both avant garde and grounded in the history of the brand. It remains a confident addition to any top tier collection that prioritizes rarity and artisanal intent.

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….
