Market price history

202420252026 $3,000

Median recorded eBay sale price for each quarter with 3 or more sales. Dashed line marks the 2026 retail price.

Investment scorecard

Momentum50Measured price direction: the median recorded sale of the last 4 months against the median of 8 to 12 months ago. 50 means flat; small samples are pulled toward 50.
Liquidity56How easily it sells: recorded sales in the last 12 months (300 or more scores 100) and eBay's 90-day sell-through rate.
Scarcity39Demand against supply. For modern pieces, how far the market sits above or below current retail, plus a lift if production has ended. For vintage, how rarely one comes up for sale.
Value entry20Where the latest quarter's median sale sits inside its own 3-year range. Buying near the low scores high; buying at the high scores low.
Condition safety77How safe a typical example is: the age of the design, plus how tightly sale prices cluster (a wide spread means condition and originality swing the price).

The story

The small steel Tank Must: the classic Tank proportions in a 22 mm case.

Small Tanks are the easiest Cartier to wear every day, and resale demand reflects it.

Also sold under references WSTA0042, WSTA0107; every one of them is counted here.

Our verdict: Sells for about 20% under its $3,750 boutique price. 24 recorded eBay sales in the last 12 months, with prices flat over the year.
