Audemars Piguet Cobra - Onyx Diamond Dial.
The unicorn of AP Cobra’s
Step into the late ’70s with a piece so rare, even seasoned collectors will question if it truly exists. This vintage Audemars Piguet Cobra isn’t just another example—it’s the example.
Housed in rich yellow gold and paired with the Cobra rope finish bracelet, this watch already sits in a category of its own. But what takes it into true unicorn territory is the dial: a flawless, glossy onyx dial, factory-set with diamonds. No cracks, no crazing, no imperfections—just a mirror-black stone dial that swallows light and turns heads.
Most Cobras come in the familiar black lacquer or champagne configurations. This? This is the dial variation that simply doesn’t hit the market. Not often. Not ever. It’s the only one available today, and one of the only documented examples to surface in years. Even if you doubled your budget, tripled it—finding another is almost impossible. That’s the beauty and the curse of a grail: you can’t chase what doesn’t exist.
For the collector who understands scarcity, for the buyer who wants something nobody else has, for the investor who knows AP stone-dials from this era are only becoming harder to acquire—this Cobra is that once-in-a-decade opportunity.

cannot recommend Danny’s Vintage Watches highly enough. I recently went through the process of selling my father’s Rolex, and the team made what could have been a stressful experience incredibly smooth and fair. I ended up trading for three absolute icons: two Cartier Tanks and a vintage Omega Speedmaster. The attention to detail on these pieces was impressive the Speedmaster was in beautiful condition, and the Cartier had been expertly re-plated and polished, looking practically new. What really sets Danny’s apart, though, is the after-care. When I unfortunately busted the crystal on one of the Cartier's eight months later, they sorted the repair quickly and for a very reasonable price. They even went the extra mile by referring me to a trusted jeweler for a ring resizing, where I’m certain their relationship helped me get a better deal. Their shop is filled with incredible finds. If you are a serious enthusiast or just looking for a fair, honest dealer, this is the place. I’ll definitely be back for my next "grail" watch!

Absolutely unreal experience. Found them from Facebook. Figured I’d browse the site. Fell in love with a patek, texted them, and they (specifically David) were so amazing and easy to chat with about options and inventory, process etc. Came in to pick up the watch - man, as you probably know - you cannot understate how great their selection is. That’s really one of the best parts as well. The service is great; they treat their clients great, prices are very good - but the curation is another huge stand out part. Anyway - these fellas were so great when we came in, that my wife was determined that we buy a watch for her, - you know just to help the business. Not for her, she insists, but because of how great the guys at the shop were. And I agreed so I obliged. :P It’s honestly a 10/10 shop. As we speak they are reworking both our watches to fit our bracelet and I’ll add photos when I pick up the watches. Heck, 11/10. They’re that good. Go there, you will not regret it! But it might be very hard not to leave with something

If I could give more than 5 stars I would. They were so kind and actually cared what I bought as a present. We've already purchased from them again and will do more in the future. Incredible selection of pristine watches
