The two-tone Tank Francaise. Gold on it, worn, and priced for it.

Cartier is the house that made the wristwatch a shape rather than a circle: the Tank of 1917, the Tortue of 1912, the Tonneau of 1906, each a case with Roman numerals, blued sword hands and a cabochon in the crown. Cartier makes them in gold and in steel, in quartz and in mechanical, and on the pre-owned market the gold ones sit where a Rolex Datejust does in price and a step above it in how they read across a table.

The two-tone Tank Francaise is the version with gold where you see it, the bezel, the crown and the centre links, and steel where you do not, which is how Cartier kept it under the all-gold price. Rebag’s Good grade is its honest tier for watches that show their life: minor scratches on the crystal, wear on the case and band. That is why this is the cheapest gold-trimmed Cartier on the page, and why the copy says to look at every photograph and ask for more before buying. Same 20mm case as the steel Francaise above it.

Rebag gives the width as 20mm, the movement as quartz, the dial as silver, and the condition as Good with minor scratches on the crystal and wear on case and band. Its rows do not name the gold; the yellow gold bezel, crown and centre links are from the photograph. No reference or accessories are stated; W51007Q4 is the catalogue match, marked confirm. Water resistance is Cartier’s figure for the model.

Rebag authenticates in-house and is not a Cartier authorised dealer, and Amazon adds its 30-day return window. Ask for the reference and the numbers on the caseback, close-up photographs of the wear, and when it was last serviced. Nothing here was measured on the watch.

This unit is sold by Rebag through Amazon Luxury Stores, authenticated by the seller with Amazon’s 30-day return window on top; it is one piece, and when it sells the listing goes away, so the second button opens the live search for Tank Francaises.

Gold Cartiers have resold close to what pre-owned buyers paid, sometimes more, sometimes less; that is a pattern, not a promise, and nothing here is investment advice.
