How do I read my Omega reference number?

To read your Omega reference number, first check the leading three digits to find the collection. Then, move on to the next two to learn what the housing and band materials are. Move on to the third set of digits, which represent the diameter and height of the housing. The next set of numbers tells you the type of movement featured in the watch. In the last two sets of digits, you'll find the dial color followed by the production sequence number. Shop a large selection of Omega watches on 1stDibs.
