The photos are bad, but I think that the watch may be worth pursuing. There seems to be some pitting on the dial, but it appears to be fairly evenly covered, and you may find it acceptable in better photos. Similarly, I think that the case appears to be fairly sharp, and I'm not seeing any obvious red flags in the movement. It could be worth your while to get better photos. Of course if the seller refuses, or blames the poor photos on his iPhone (which seems to be a typical excuse), you will be left with a risky decision.
