Investment scorecard

Momentum100Measured 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.
Liquidity100How easily it sells: recorded sales in the last 12 months (300 or more scores 100) and eBay's 90-day sell-through rate.
Scarcity35Demand 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 safety79How 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 Reduced was a smaller, automatic Speedmaster built on an outsourced base movement with a chronograph module.

It offered the Moonwatch look at 39mm and a lower price.

For years it was the cheapest way into a Speedmaster.

Its prices have firmed recently as current model retail climbs.

Our verdict: The cheapest way into a Speedmaster, and it has been quietly climbing. Automatic, 39mm, easy to resell, but the modular movement needs a good watchmaker.
