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.
Liquidity62How easily it sells: recorded sales in the last 12 months (300 or more scores 100) and eBay's 90-day sell-through rate.
Scarcity33Demand 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 entry36Where 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 safety90How 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 watch purists swore Rolex would never make: a two-tone saturation diver. A 1,220m tool watch with yellow gold on the bracelet is gloriously unnecessary, which is exactly its charm.

It trades comfortably below retail, like most gold-touched sports models, and sells slowly. Buyers either get the joke immediately or never will.

A two-tone saturation diver is a contradiction in terms, which is why it works: 1,220 meters of capability wrapped in yellow-gold deck jewelry. The watch equivalent of a tuxedo with steel-toe boots.

Rolex makes category-breaking combinations rarely, and they tend to age into cult picks once discontinued. This one is still in production and still discounted, the full cycle lies ahead.

Our verdict: Buy pre-owned at the discount and enjoy the most contrarian Sea-Dweller ever made. Just don't expect the market to come around quickly.
