Omega occupies a unique position in the secondary market — a brand with both the world's most historically significant chronograph and a decades-long presence in popular culture through James Bond and the Olympics. The vintage Speedmaster market is driven by a well-established hierarchy: Caliber 321 examples command significant premiums over Cal. 861 references, and within the 321 family, originality of parts — correct dial, hands, movement, bezel, and caseback for the specific reference and production date — is the primary determinant of value. A CK2915 in original condition with matching-numbers movement can exceed $100,000; a heavily restored or parts-mixed example is worth a fraction of that. The stepped-dial 145.022-69 with "Straight Writing" caseback, the last 145.022-71 with stepped dial, and original-condition Cal. 321 examples all carry meaningful premiums over later references.

On the Seamaster side, the vintage SM300 (165.024 and 166.024) is increasingly recognized as one of the great vintage dive watches — particularly military variants issued to the British Army, Royal Navy, and SAS, and COMEX-supplied references, which are among the rarest and most valuable Omegas in existence. The Diver 300M James Bond generation has its own devoted collector base, and the Planet Ocean and Aqua Terra hold their value well in the secondary market as practical, well-built watches with modern Master Chronometer movements. Constellation pie-pan pieces in yellow gold, De Ville tourbillons, and gold special editions of the Speedmaster round out the Omega collector picture.
