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.
Liquidity59How easily it sells: recorded sales in the last 12 months (300 or more scores 100) and eBay's 90-day sell-through rate.
Scarcity36Demand 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 safety88How 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 Tank Must is Cartier's entry steel Tank, relaunched in 2021 to replace the Tank Solo.

The Tank shape dates to 1917; Louis Cartier is said to have drawn it from the outline of a tank seen from above.

The 2025 version has a high-autonomy quartz movement that lasts years on one battery.

Also sold under references WSTA0041, WSTA0106, WSTA0108; every one of them is counted here.

Our verdict: Sells for about 23% under its $3,900 boutique price. 28 recorded eBay sales in the last 12 months, with prices flat over the year.
