Market price history

Investment scorecard

Momentum76Measured 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.
Liquidity80How easily it sells: recorded sales in the last 12 months (300 or more scores 100) and eBay's 90-day sell-through rate.
Scarcity62Demand 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 entry40Where 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 safety78How 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 automatic XL Tank Solo, made until 2021. Earlier examples use an ETA-based movement; later ones carry Cartier's in-house 1847 MC.

It now sells for close to what it cost new, which is rare for a steel Cartier.

Also sold under reference W5200028; every one of them is counted here.

Our verdict: Sells for about 7% under its $3,450 last price. 95 recorded eBay sales in the last 12 months, and prices are up 10% over the year.
