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.

Liquidity24How easily it sells: recorded sales in the last 12 months (300 or more scores 100) and eBay's 90-day sell-through rate.

Scarcity48Demand 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 safety65How 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

Factory diamonds matter: Rolex-set stones keep value, aftermarket stones destroy it. This is the reference that teaches the lesson.

Trades under retail while current; the long game is the eventual 28mm discontinuation.

Factory diamond bezel on the current 28, with the critical word being factory: Rolex-set stones on a Rolex watch hold value where aftermarket settings destroy it. The 'RBR' in the reference literally denotes the diamond bezel.

Buying these pre-owned at the standard gem-set discount is how smart money wears diamonds: let the retail buyer absorb the setting premium, collect the sparkle at roughly 10 to 20 percent off.

Our verdict: Buy factory-gem-set only, ideally pre-owned at the discount. Paper trail is everything with diamonds.
