The Cartier Tank Louis Cartier WGTA0346 is the large Tank Louis Cartier in rose gold: a rectangular 38.1 mm by 27.8 mm case with a silver dial, Roman numerals and an alligator strap. It is a dress watch in the line that descends from Louis Cartier's 1917 Tank design, with the gold case, the curved side bars and the thin profile that define the model. This guide covers the specifications we can confirm, what the Tank Louis Cartier is, how it differs from other Tank models, how the large size sits against the other sizes in our catalogue, how it wears, dated prices from October 2026 and what to check before buying. Bizak & Co. sources the WGTA0346 to order; the Cartier Tank collection lists the configurations we can seek.

Sources: Phillips watch auctions and Sotheby's watch department catalogue Tank watches and show how the model is described and dated at auction, and Cartier's own website lists the current Tank Louis Cartier range and sizes. Where a specification above is marked as unconfirmed, we have left it open rather than guess.
What is the Tank Louis Cartier?
Louis Cartier drew the Tank in 1917, taking the plan view of a military tank as the model for the case, with the side bars as the tracks and the crown and strap lugs as the turret. It went on sale in 1919, and the Tank has been in production in some form ever since, in many variations. The Tank Louis Cartier is the version closest to the original in spirit: a thin, rectangular, precious-metal case with curved side bars and a hand-wound movement. It is a different watch from the Tank Must, which is a more affordable steel line, and from the Tank Française and Tank Américaine, which have their own case shapes.
The model is sold in several sizes and metals, and the sizes carry different names on different pages. Our catalogue lists the 38.1 mm by 27.8 mm size as large, so check the dimensions of the exact watch against the reference, not the size name.
What does manual winding mean for daily wear?
A manual-winding movement has no rotor, so you wind the crown by hand to power it, usually once a day or every couple of days, and the movement runs for a day or more after a full wind. This suits a dress watch: the case stays thin because there is no rotor to accommodate, and the wind becomes a small daily ritual. If you want a watch you can leave in a drawer and pick up running, a manual watch is less convenient than an automatic one. The Tank Louis Cartier is best for the wearer who wears it most days.
Which Tank Louis Cartier size and metal?
| Reference | Size and metal | Bizak catalogue ask, 1 Oct 2026 |
|---|---|---|
| WGTA0346 | Large 38.1 mm by 27.8 mm, rose gold, alligator | US$16,099 brand new |
| WGTA0024 | Medium 33.7 mm by 25.5 mm, rose gold, bracelet | US$29,299 brand new |
| WJTA0014 | Medium 33.7 mm by 25.5 mm, rose gold, diamond bezel, alligator | US$23,099 brand new |
| WGTA0059 | Medium 33.7 mm by 25.5 mm, yellow gold, red and opaline dial, alligator | US$13,799 brand new |
| WT200006 | Extra-large, white gold, diamond bezel, alligator | US$33,799 brand new |
The comparison shows what drives the price: a gold bracelet, diamonds or the white gold case each add substantially, while a plain gold case on a strap is the entry point for a Tank Louis Cartier. The WGTA0346 is a plain rose gold case on alligator in the largest standard size, and sits at the lower end of the catalogue range because it has no stones and no gold bracelet.
How does a 38.1 mm by 27.8 mm Tank wear?
A rectangular case wears differently from a round one: at 38.1 mm tall by 27.8 mm wide, the WGTA0346 sits closer to a 36 mm round watch on most wrists, because the width is what you see across the wrist. The proportions are slim and flat under a shirt cuff, which is the point of a Tank. Rose gold is warm against the silver dial and works well on most skin tones. Try it on, since the proportions suit a slim wrist and a larger one differently.
How much is a Cartier Tank Louis Cartier WGTA0346? Prices in 2026
- Retail. Cartier publishes recommended prices on its own website and in its boutiques. Check the current figure for the large rose gold Tank Louis Cartier there, as Cartier updates prices from time to time.
- Bizak catalogue ask. On 1 October 2026 our sourced catalogue listed the WGTA0346 at US$16,099 brand new, sourced to order. Other Tank Louis Cartier references in the catalogue were listed between about US$13,799 and US$38,999 depending on size, metal, bracelet and diamonds.
- What moves the price. A full set with box and card, a purchase date close to today, an unmarked gold case and an unmarked strap each add. A watch with polish marks on the case or a replaced strap should be priced lower.
Those figures describe what we saw and will move. Ask for a dated quote for the exact size and set; our Patek Philippe price guide shows how we compare quotes for precious-metal dress watches, which is a useful reference point for a gold Tank.
Is the Tank Louis Cartier a good investment?
Treat it as a dress watch to wear rather than a store of value. Cartier's Tank has a long lineage and steady demand, and gold Tank Louis Cartier watches hold their desirability better than most dress watches, but a brand-new watch bought at a premium over boutique price may not return it. Buy it for the shape and the case. If resale matters, ask for a written cash-buy assessment before you commit.
Buying a brand-new Tank Louis Cartier: what to check
- Full set. Box, outer packaging, Cartier card and booklets. The serial on the card should match the case.
- Reference and case back. The reference and the serial number should be on the case back; check they match the WGTA0346 on the card.
- Case and side bars. Rose gold shows contact marks. Look at the side bars, bezel edges and lugs under good light, and check that the case surfaces are crisp with no try-on drag marks.
- Dial. Silver dial with even Roman numerals and a clean minute track; the printing should be crisp and the hands straight and centred.
- Crown. The crown should be seated properly and wind with a smooth, even feel; check that the setting position works.
- Strap and buckle. Alligator strap unmarked, with a buckle signed and matching the case metal.
- Price against the band. A brand-new rose gold Tank offered far below the catalogue range needs a clear explanation of its source.

Caring for a gold Tank on alligator
Treat the watch as a dress watch: keep it away from water, take it off for exercise and rotate it with other watches so that the strap rests. Alligator leather dislikes moisture and perfume, so wipe it with a dry cloth and store the watch flat in its box. A manual movement benefits from regular winding and a service by Cartier at intervals recommended on the card.
