Piaget Altiplano 9791 AB2 - 18K White Gold Onyx & Diamond Dial

Trade In
Details

The dial tells you exactly what this is

This Piaget comes from the brand’s most confident jewelry era, when ultra thin construction met real stone dials and integrated gold bracelets. The onyx dial with diamond accents is the entire point. It's flat, deep black nature allows the wearer to get lost in the dial. The integrated bracelet complements the watch perfectly, creating a seamless balance where neither the dial nor the band steals attention from the other. 

Why this configuration matters

Onyx dials are fragile and difficult to work with. Many cracked during production or did not survive decades of wear. Finding one that remains intact is increasingly uncommon. This dial is clean and uncracked, which is the first thing serious collectors look for.
The integrated 18k white gold bracelet and bezel complete the design. Piaget did not treat the bracelet as an accessory. It is part of the architecture of the watch. When these bracelets stretch or are separated, the watch loses its identity. This one remains tight and well preserved. Manual wind suits Piaget’s design philosophy here. It allows the case to stay slim and keeps the focus on form and material rather than mechanics.

What you need to know before wearing it

Condition is very good. The bracelet is in great shape. The onyx dial is perfect and intact. The crystal shows small scratches near six and nine o’clock that are visible only upon close inspection. The watch runs exceptionally well at approximately zero seconds per day after passing by the test bench. 

For one looking for their statement dress piece.

This is Piaget doing what it did better than anyone else in the 1980s. Stone dial, precious metal, integrated design, and ultra thin proportions. Nothing here was meant to be common. It works for someone who values material rarity over complication and understands that condition on stone dial Piagets is everything. Clean, intact, and increasingly difficult to replace once it leaves the market.

History

Georges Edouard Piaget founded his manufactory in La Côte-aux-Fées in 1874, and for decades the company's reputation rested on its ability to produce movements of exceptional thinness — calibers that other high houses bought and put in their own watches. When Piaget began producing watches under its own name in the late 1950s and 1960s, it brought that ultra-thin expertise directly to the dial.

The Altiplano is Piaget's flagship ultra-thin collection, a direct expression of that founding expertise. The Grenade is a bold gem-set cocktail watch — all pave diamonds, colored stones, and sculptural bezels — occupying the space between watch and jewel without apology. The Limelight Gala, produced from the 2010s onward, is the modern heir to that cocktail tradition: an 18-karat white gold round case set with diamonds, a slim quartz movement, and a leather strap. All three collections reflect the same dual mastery that Piaget has always commanded: the thinnest movements in the world, in cases worth wearing.

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….
