What I can say though is that I wouldn't buy it without seeing the movement first. I think the watch is rather appealing with white cross hair dial in gold so if I wanted it as a wearer, not collector, I'd start talking to the seller about it being overpolished, ie the sharp edges of the lugs for instance rounded, and the fact that it's gold capped (most likely) which lessens the value. I'd keep schtum about the fact that the dial, in this pic at least, looks original.
Unless white cross hairs are supremely collectable, I don't know if they are, I'd say around 600$. (not less though) But again, movement pics first.
