Investment scorecard

Momentum59Measured 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.

Liquidity89How easily it sells: recorded sales in the last 12 months (300 or more scores 100) and eBay's 90-day sell-through rate.

Scarcity30Demand 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 entry27Where 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 safety88How 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 fourth-generation Diver 300M arrived in 2018 for the model's 25th anniversary, bringing a ceramic dial and bezel and the anti-magnetic calibre 8800.

The line traces back to the 1993 Seamaster Professional that Pierce Brosnan wore as James Bond from 1995.

It keeps the signature helium escape valve, scalloped bezel and skeleton sword hands.

It is the default Omega dive watch and one of the most traded Omega references.

Our verdict: Omega's best-selling diver, easy to buy and easy to sell, but at about two thirds of retail once worn. A great watch to own, a poor one to flip.
