Median recorded eBay sale price for each quarter with 3 or more sales. Dashed line marks the 2026 retail price.
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.
Scarcity42Demand 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
Omega restarted production of the calibre 321 in 2019, the column wheel movement used in Speedmasters through the Apollo era.
This steel model uses a 39.7mm case modeled on the 105.003 that Ed White wore on the first American spacewalk in 1965.
Each movement is built by hand in a dedicated workshop in Biel.
It is the closest modern equivalent to a 1960s Speedmaster.
Our verdict: The modern Calibre 321 trades close to its retail, which is rare for Omega. Few change hands, so expect to wait for the right buyer when you sell.
