Hi
Since I don't understand whatever language that the description is written in, I can only assume from the red arrows that there are some serious case dents in this watch.

To me, it does appear to be original. If you like the style of the watch and can purchase it for a good price it might be worth it. Then you might look for another case or try to get that one repaired. Or just wear it with a smile. BTW, what is the currency conversion to US$ to judge fair value of the offer?

The old saying is to buy the BEST condition model that you can afford. Therefore, IMHO, I would be inclinded to spend your money on a better example of that model or on one of the more popular models from the 1970s like a Carrera or Autavia.

PS-To show the watch pic, I went to the site you listed, right clicked on the photo, copied the url listing for the photo and posted it in the "Optional Image URL" in my reply.
