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.

Liquidity42How easily it sells: recorded sales in the last 12 months (300 or more scores 100) and eBay's 90-day sell-through rate.

Scarcity40Demand 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 entry50Where 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 safety80How 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 SolarBeat Tank Must charges from light that passes through tiny perforations hidden inside the Roman numerals.

Cartier rates the battery for about 16 years. It sells less often than the regular quartz Tank Must.

Also sold under references WSTA0059, WSTA0122; every one of them is counted here.

Our verdict: Sells for about 13% under its $3,900 boutique price. 8 recorded eBay sales in the last 12 months, with prices flat over the year.
