Investment scorecard

Momentum51Measured 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.

Liquidity67How easily it sells: recorded sales in the last 12 months (300 or more scores 100) and eBay's 90-day sell-through rate.

Scarcity69Demand 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 entry66Where 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

A Sea-Dweller made for only about three years, between the classic 40mm design and the larger 43mm model that replaced it.

It kept the 40mm size and the clean dial with no date magnifier, which many collectors consider the ideal Sea-Dweller formula.

Because the run was so short, it has a quiet cult following and trades above its final retail.

It is a great example of how short production runs create collectible modern Rolexes.

Our verdict: The short-run modern Sea-Dweller collectors quietly prefer.
