I have an Omega ladies watch and I am trying to determine if it is real or a fake. The face of the watch indicates it is an Omega Costelletion 21 prix. It has 26 stones (diamonds?) around the face of the watch. The back of the watch is stamped with the word Omega and the omega symbol within a triangle. It also indicates it is 18k 0.750 and that it is Swiss made.
Can any one assist with this inquiry?
