An Omega watch serial number can be found engraved on the inside of the watch back or on the exterior of the watch depending on when the watch was manufactured. If the serial number is located on the inside of the watch, a jeweler may have to open the watch to prevent damage. The serial number can also be found on the guarantee card that is included with the watch.
An Omega watch serial number is eight digits long and serves as a unique identifier for the watch. All Omega watch serial numbers are permanently stored in Omega's database. Owners of authentic Omega watches can request a certificate from Omega as proof of the watch's authenticity.
On some Omega watches, the serial number may be laser-etched and very small. If the serial number is small and hard to read, a magnifying glass or lighted eye loupe may be necessary to read the serial number.
Omega watch serial numbers help buyers determine whether the watch is authentic or counterfeit. Prior to purchasing an Omega watch, prospective buyers can request the serial number from the seller and contact Omega to confirm that the serial number is valid and in Omega's database. Alternatively, licensed Omega dealers or experienced jewelers can help determine whether the watch is authentic prior to purchase.
