Omega has released many special editions to enrich the family of Seamaster collection such as Olympics special editions or 007 series editions.
The steel case Omega Seamaster fake watch with yellow second hand 007 limited edition has still been famous in secondary market. The pattern on the dial is really distinctive and charming.
The other one I want to recommend is the ref.2230.50 – the Copa America limited edition. Although the amount of 9999 pieces makes it not worth collecting, the white gold bezel copy Omega could hold its value very well. It is difficult to find another one to contend against it.
