Agree with the above. This looks like an original watch to me and condition seems good with the dial paint/anodization(?) loss on the edges. I'm not sure how these watches age, so could be natural or could it be due to servicing and handling? I don't know.
Prices are all over...it seems that this model and its variations lives in the $500-2000USD range which isn't too helpful. It seems most of the nicer ones actually sell for $700-1300USD. For yours, it seems that the square (earlier) case (there were more rounded/tonneau shaped ones that don't seem to fetch as much) seems to bring a little more. Additional plusses are the bracelet and the dial being a cool color and having the applied hour track circle thing.
Here's a similar model in nice condition with basic dial and a strap that sold for approx 600EUR on eBay:
What does your research tell you? Are you comfortable with what the condition and price of this piece?
Good luck. This looks like a cool watch. Let us know what you decide and post some pics if you get it!
