Medieval Omega series has no number.

Medieval Omega constellation series has no number, so it is necessary to verify the authenticity of the following table. Omega watches have production serial numbers, and they are the first watch, which is unique in the world. Generally engraved on the back cover of the watch or the back of the shell claw of the watch, it is a string of 8 digits. If it is a mechanical watch, the 8-digit production serial number will also appear on the edge of the movement splint, and the production serial number of the watch case is the same as that of the movement. The serial number of the real watch is engraved, which is very deep and clear. If it is engraved on the back cover of the watch, it will be consistent with the radian of the back cover of the watch, that is to say, the numbers are also arranged in an arc, while fake watches are generally horizontal.
