Any idea on value of this gen Franck Muller 5850 RET?

[PaulJaffe]

I purchased this watch from a AD some time ago and am thinking about parting with it. I have box and all papers. It is rose gold and the model # is 5850 RET. Does anyone have any idea of an approx value for this watch? I couldn't find any actual transactions online or on ebay, but did find some similar models for sale at Christie's watch auction that ranged from 5k-7k, but not the exact model. I have enclosed some photos below. Thanks!!

Thank you! I came across this at Christies which turns out to be the exact watch, sold for $8400. The auction took place in 2005 though...would this still be an accurate price?

If I were selling it, I'd certainly reference that auction as a fair price. Looks like it sells for up to $12,300...http://www.thefinestwatches.com/index.cfm/fuseaction/catalog.viewProduct/productId/9203
