Investment scorecard

Momentum46Measured 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.

Liquidity64How 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 entry28Where 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 safety73How 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 midsize steel Santos 100, the smaller sibling of the Santos 100 Large.

It trades for about what the large size does, which makes it popular with smaller wrists.

Also sold under reference W20126X8; every one of them is counted here.

Our verdict: Sells for about 42% under its $6,850 last price. 27 recorded eBay sales in the last 12 months, and prices are down 2% over the year.
