Cartier Tank: value and pre-owned prices (Must, Louis Cartier, Française)

Designed in 1917, the Tank is Cartier's most recognisable watch and one of the great classics of dress watchmaking. Yet it is not one watch but a family: from the vermeil Musts of the 1970s to the gold Tank Louis Cartier, by way of the Tank Française with its integrated bracelet and the curved Américaine, pre-owned prices run from €1,500 to several tens of thousands of euros. To value a Tank, you first need to know which one is on your wrist, then look at three criteria: metal, movement and size.

One shape, several families

Louis Cartier designed the Tank in 1917; it went on sale from 1919. Side shafts (the "brancards"), a rectangular dial, Roman numerals, a railway track and a cabochon on the crown: this vocabulary has barely changed since. The families that matter on the pre-owned market:

• Tank Louis Cartier (1922): the version with softened corners, now made only in gold, with manual winding on the large model. The most faithful to the original design. See the WGTA0011 page.
• Must de Cartier (late 1970s): the Tank in vermeil, gilded sterling silver, launched to broaden the house's clientele. It now makes up most of the affordable vintage market.
• Tank Américaine (1989): an elongated, curved case, heir to the Tank Cintrée. First made in gold, it has been available in steel since 2017. See the WSTA0017 page.
• Tank Française (1996): integrated steel bracelet, chunkier case. Replaced in 2023 by a version with a refined design, in quartz or automatic. See the medium model W51011Q3 page.
• Tank Solo (2004 to 2021): the entry-level steel Tank, quartz or automatic. See the W5200014 page.
• Tank Must (since 2021): the revival of the Must, in steel, with quartz, SolarBeat solar or, on the extra-large model, automatic movements. See the pages for the large model WSTA0041 and the extra-large model WSTA0040.

Add to these the Tank MC, Tank Anglaise, Tank Divan, the Basculante and limited-series gold reissues, each with its own market.

2026 price guide by family

The ranges below come from our October 2026 data: about a hundred Tanks, roughly four fifths private-party listings, mostly American and converted into euros, and one fifth prices displayed by certified dealers. Retail prices come from our catalogue and are indicative.

Across the whole model, the median private listing sits around €3,050 and the dealer median around €4,000. The gold families rest on few data points, and diamond-set versions, common among dealers, are excluded from the ranges: they are valued piece by piece. For a dated estimate, the Tank page and the valuation tool refine by reference, year, condition and accessories.

What the price guide tells us

1. Quartz steel depreciates, then stabilises. A Tank Must large model resells privately at up to 30% below its retail price, closer to it when recent and complete. This is the logic of a widely distributed watch available in boutiques; depreciation is concentrated on the first resale, as we explain in new or pre-owned: first-year depreciation.
2. Gold holds up better than steel. A 2025 Tank Louis Cartier WGTA0011 recorded at around €12,500 between private parties sits very close to the retail price in our catalogue, while a large steel Tank Américaine changes hands about 30% below its own. Precious metal, relative rarity and a collector audience explain the gap; the gold price also weighs on the new price, and so on the benchmark.
3. Vintage vermeil is the way in. At €1,350 to €2,400, a 1980s Must de Cartier offers the Tank design for less than any modern Tank. But vermeil wears: plating worn through to the silver shows and is heavily negotiated.
4. Limited gold series are another world. A rose-gold Tank Chinoise recorded at around €20,600 between private parties, a recent Tank à Guichets listed at close to €170,000 by a dealer: these pieces belong to the collectors' market, not to the model's value.

Quartz or mechanical, steel or gold

Quartz dominates the Tank, and its audience does not see that as a weakness: it is a thin, light watch that never needs winding. Pre-owned, quartz versions sell faster and for less, mechanical versions more slowly and a little higher. The gap between a large quartz Tank Must and an extra-large automatic is around €1,000 to €1,500 in our data, size included.

Two maintenance points separate the families. A quartz Tank needs little, but a forgotten battery can leak and damage the movement: ask when it was last changed. A mechanical Tank is serviced like any watch: at Cartier, our benchmarks put a full service at €400 to €800 for a watch with simple functions, detailed in luxury watch servicing: cost and frequency.

Checks before you buy

• The brancards: on such a crisp shape, polishing that rounds the edges shows immediately and costs value. Our article to polish or not to polish your watch details what a buyer will accept.
• The crown cabochon: often chipped, or replaced with a non-original part.
• The [dial](/glossaire/cadran): on vintage Musts, check the signature and the condition of the lacquer; on an older Tank Louis Cartier, have the originality of the dial and the gold buckle checked.
• The bracelet or strap: pre-2023 Tank Française bracelets develop play at the attachments; an original Cartier leather strap is expensive to replace.
• The papers: the serial number engraved on the caseback must match the warranty card. On a Tank selling for around €3,000, the gap between a bare watch and a full set weighs heavily in proportion; we quantified it in box and papers: impact on price.
• [Authentication](/glossaire/authentification): vintage Musts and Tank Françaises are widely copied. Have the watch opened, or buy from a dealer who guarantees authenticity.

Selling a Tank in 2026

• Name the family and size: buyers search for "Tank Must large model" or "Tank Française medium model"; "Cartier Tank" alone buries the listing.
• Specify the movement and, for a quartz version, the date of the last battery change.
• Compare the channels: on a €3,000 Tank, a consignment commission weighs heavily. Our comparison of sales channels sets out the options, and why trade-in prices sit below market value explains the gap with a professional buyer.

In France, most steel Tanks sell below the €5,000 threshold, in which case a private seller is exempt. Gold Tanks often exceed it and fall under the 6.5% flat-rate tax, or by option the capital gains regime; the details are in our article on the taxation of selling a watch, and the steps on the sell your watch page. If you live elsewhere, check the rules that apply in your country.

In summary

A quartz steel Tank resells for roughly €2,500 to €3,500, a vintage vermeil Must for €1,350 to €2,400, and a recent gold Tank Louis Cartier close to its retail price. Metal, movement, size and the condition of the brancards account for most of the value. Before buying or selling, calculate the value of your Tank from its reference, year and condition.
