Authentic or Replica/worked on - Omega Seamaster 600 Ref. 135.011

[Gwaxy]

I am not quite sure about this Seamaster 600 Ref. 135.011 which I found. It almost looks too good to be true/ too clean. Also I can't seem to find any other Seamaster with a plain black dial. The writing also looks a bit to thick?
Maybe someone has a bit more of an idea than me and can help me out?

The movement looks fine (to my eyes, but others may chime in), but the dial looks redone, and not amazingly. Also is it me or are the hands in terrible shape?

I’d pass on this. SM600s of this vintage are not hard to find, and with a little more searching and patience, you should be able to locate one in far better condition.

The dial is refinished, and the hands look pretty crappy. The watch is real I would say.
