I just got this "probably" 166.020 for my 30th birthday. The thing i am questioning is the watch dial. Cant seem to find any matching image of it. Is it a fake? Is it a model a cant find. If you guys could help me out that would be great

 

Dial looks pretty good to me. Here is a similar example, enjoy it.
