Cartier Tank Obus - 18K Yellow Gold

Details

The Quadrant Enamel Classic

The Cartier Tank Obus is a distinct departure from the elongated rectangles typically associated with the brand. This 1980s execution, often referred to as the "Quadrant," utilizes a perfectly square 20x20mm 18k yellow gold case. What sets this specific reference apart is the bezel; rather than leaving the gold plain, Cartier inlaid it with black enamel Roman numerals. This design choice pushes the hour markers to the bezel, allowing the white dial to remain open and minimalist. It is a sophisticated, geometric take on the Tank lineage that feels more like a piece of stationary architecture than a standard timepiece

A Rare Geometric Execution

In the world of vintage Cartier, the Obus occupies a niche space for collectors who appreciate "shaped" watches. The square proportions give it a stout presence on the wrist despite its refined dimensions. The contrast between the high-polish 18k yellow gold and the crisp black enamel creates a graphic intensity that is signature to Cartier’s early 20th-century design language, revived here for the 1980s. It is a configuration that prioritizes the case's silhouette, making the bezel the primary dial while the internal white face serves as a clean, secondary backdrop.

Sharp Gold And Preserved Enamel

The 18k yellow gold case is in good condition, maintaining its sharp square corners and the distinct "bullet" lugs that give the Obus its name. Crucially, the black enamel Roman numerals on the bezel are well-preserved, retaining their deep pigment and clean edges. The white dial is excellent, showing no signs of spotting or degradation. The watch is currently fitted to a leather strap with an aftermarket buckle. Mechanically, the watch is being sorted for a fresh battery as part of our intake process runs great.

A Sophisticated Square Alternative

This is a watch for the Cartier enthusiast who already owns a Tank Louis or a Santos and wants something more obscure. The Tank Obus offers a level of vintage charm and geometric character that is hard to find in modern catalogs. It functions as a formal dress watch with a heavy lean toward jewelry, offering a look that is both historically grounded and visually unique. It is a rare, intentional design that remains one of the most interesting "hidden" references in the Cartier archive.

History

The Tank emerged during the First World War when Louis Cartier drew inspiration from the new Renault FT‑17 tanks.  In 1917 he sketched a watch with straight brancards flanking a rectangular case, echoing the treads and hull of the tracked vehicles .  A prototype was presented to General John Pershing, and the first production pieces appeared in 1919 .  Unlike most wristwatches of the era, which were adapted pocket watches, the Tank was conceived from the outset as a wristwatch for men and women, signalling a modern approach to timekeeping.The design philosophy of the Tank is rooted in simplicity and proportion.  The rectangular case is bounded by vertical brancards, while a clear dial bears Roman numerals and a railroad minute track reminiscent of Parisian architecture .  Blued steel hands and a sapphire cabochon crown became recurring elements, and the overall dimensions were guided by the Golden Ratio .  These features create a formal clarity that distinguishes the Tank from round watches and give it versatility across genders and eras.When it was introduced, the Tank reflected cultural currents of the early twentieth century: mechanisation, the decline of ornate Victorian aesthetics and the emergence of Art Deco geometry.  Its clean lines resonated with artists and intellectuals seeking modern forms.  Over the decades Cartier developed numerous variations—Tank Cintrée, Chinoise, Louis Cartier, Américaine and Française—that adjusted case curvature, size and detailing but always preserved the original rectangular silhouette.  Such continuity allowed the model to evolve without losing its identity.Collectors value the Tank for its historical significance and design purity.  It stands as one of the earliest purpose‑built wristwatches and as a symbol of the shift from pocket to wrist timekeeping.  Its timeless form, adaptable to both formal and casual contexts, continues to attract enthusiasts who appreciate Cartier’s blend of jewellery craftsmanship and watchmaking heritage.

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….
