•Reference number: The reference number is one of the important factors that says whether the watch is original or fake. Every watch brand has its own reference number. So, by seeing the reference number of a watch you can recognise from which brand and collection the model belongs. The number is carved inside the case back. Omega uses these numbers to differentiate between watches and their types. For instance, the 130.23.41.22.06.001 is from Omega Constellation Globemaster.
•Movement: The movement of a watch is also significant to determine whether it is authentic or replica. Omega models are loaded with certain movements and they are clearly mentioned on the movement. For example, the Omega Seamaster Aqua Terra 220.12.41.21.02.001. If you can’t find the movement mentioned on the watch, you can find it from the Vintage Omega Database.
•Dial: You must closely follow the dial of an Omega watch before buying it. If everything is proper then it is an authentic one. The easiest way to know whether it is a fake watch is by highlighting the spelling or mistakes related to engraving. The “Omega” logo of an original piece is made with different piece of metal that is engraved on the dial. If it is painted, then the watch is fake. For example, the Omega Commander’s Watch Limited Edition 212.32.41.20.04.001 watch.
•The Case: The case back of an Omega watch is stamped with a seven or eight-digit serial number that is distinctive to the watch. You can see the serial number of the piece and make sure that the model it indicates to accurately matches the one you are scrutinizing, else it’s a forged one. An authentic Omega watch has its serial number carved inside the case back. For instance, the Omega Constellation 123.20.27.60.52.001 watch.
•The functions: If you have decided to buy an Omega watch, then at first check out its features. The watch with more than one crowns but no corresponding dials is a replica piece. If you have any doubt about your Omega model, then you just take it to a watch manufacturer and make them investigate it.
