I'm not personally familiar with the market for these, but this site tracks auction prices. Obviously the asking price is at the top of this range, which is not surprising. I will mention that there is some significant damage to the upper sub-dial, and minor damage to the right-hand sub-dial, so I don't think one can say that this is truly pristine. Obviously it's very nice, but when you are asking a price like that, people are going to look very hard for flaws.
