Cartier Santos Octagon 8090 - 18K Yellow Gold White Roman Dial

Trade In
Details
A Geometric Twist On A Cartier Icon
The Santos is the foundation of Cartier's watchmaking history, but the Octagon variant offers a compelling departure from the classic square case. Produced for a limited time, this execution softens the lines of the original design while retaining the signature bezel screws and integrated bracelet. To find one in solid 18K yellow gold moves it from a simple design alternative into a much more significant category. It is a rare and elevated take on one of the most important models ever made.
Solid Gold From Case To Clasp
This is a top-tier execution of a beloved reference. The entire watch, from the case and bezel to each link of the bracelet, is crafted from solid 18K yellow gold. This gives the watch a substantial weight and presence on the wrist that steel and two-tone models cannot match. The classic white dial with printed Roman numerals and hands provides perfect legibility, while the signature synthetic sapphire cabochon set in the crown completes the classic Cartier look.
A Well Preserved Example
This example is in very good condition. The solid 18K yellow gold case, bezel, and bracelet show little to no significant scratching, with only minor surface marks consistent with the nature of solid gold. The white Roman dial is clean and well-preserved. The integrated bracelet is tight and shows excellent structural integrity for its age. As with every watch we offer, this piece has been verified as mechanically sound and is ready to wear.
Distinctive And Immediately Recognizable
This is a watch for someone who appreciates the history of the Santos but wants a version with more individuality. The octagonal shape is subtle enough to be versatile but different enough to be noticed. As a solid gold piece, it functions as both a serious watch and a substantial piece of jewelry. It is a fun, uncommon, and deeply elegant expression of Cartier design from a great era.

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….
