A guide to the Omega references tracked here
WristMarkets currently covers 3 Omega references. This is a selected catalogue, not the manufacturer’s complete range. The references below use manual and automatic movements, with case diameters from 41 to 42 mm.
Compare Omega watches by reference
The reference identifies the watch more precisely than its collection name. Compare case size, movement and dial first, then open the exact reference for its specifications, sources and available buying or selling offers.

Which Omega price am I seeing?
Prices marked Retail are external retail references. Community asks and bids are separate expressions of selling and buying interest. Availability, condition and the seller’s currency matter when comparing offers; a listed price is not a completed sale.
Read the pricing methodology →How do I choose a reference?
Start with the case size and movement that suit your use, then compare individual references and accessories. Catalogue dimensions do not replace a fit check. A similar name or dial colour does not establish that two references are identical.
