Almost all Omega watches have production serial numbers, and they are one watch and one number, which is also unique. Generally engraved on the back cover of the watch or the back of the shell claw of the watch. This is an 8-digit number. 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.

At present, the production serial number of Omega watches is engraved on a claw position on the back, and the numbers are engraved very small and dense, so it is impossible to imitate fake watches at present. The serial numbers of fake watches are basically the same number, no matter whether they are men's watches or women's watches, no matter what model.

2. Look at the sign of the watch case.

Especially for K-gold watches, there are many marks on the case, such as the pattern of the balance, the mark of 18K or 750, the dog head of Saint Bona or the female head of the "goddess of national protection". These marks are printed small and clear, while fake watches are often thick and fuzzy.

3. look at the logo of the strap.

If it is a metal strap, some marks will be engraved at the discount of the strap, and there must be a strap number. The marks of fake watches are generally relatively large, shallow and rough. This place is technically difficult to do, and fake watches are often exposed here. If it is a K-gold watch, the ring buckle of the strap must also be K-gold, and the logo of K-gold must be engraved. No, it's gold-plated. Recently, some Omega watches with straps have been found to have problems in this place, so at least they are not original straps.
