I followed this auction that ended the weekend http://www.ebay.com/itm/271737923570?rmvSB=true&clk_rvr_id=766288200774&afsrc=1&rmvSB=true
I reported to eBay twice and e-mailed Rolex St James. Nothing was done.
Some poor sucker won't have a clue their new pride and joy is a fake & some low life made a mint.
This is a very high grade fake. Although to anyone with a good reference and a keen eye would know within seconds what it was.
For a excellent reference blog on vintage Rolex then have a look at this http://stefanomazzariol.blogspot.co.uk/ this is a fantastic reference sublime photo's.
A couple of easy tells on the eBay watch are, apart from the seller & listing that you would run a mile from...
The coronet on the dial has a gaping hole where the gen has a squashed oval.
The numbers of the 110 on the bezel are too widely spaced, this is a common issue with all the fake bezels.
The wording on the dial "Rolex Oyster Cosmograph" apears bolder, fatter and less defined than on the genuine.
Look at the eBay picture 5, zoom in and see the gap between the bezel & case.
Look at the engraved bridges on the eBay version, they look newer and a different shade than the rest of the movement.
Look at the regulator screw on the eBay movement, there is no groove in the regulator plate under the screw to adjust the arm.
Considering that a Valjoux 72- movement is going for £800 plus on eBay you get an idea of how much money & effort has gone into this to pass it off as genuine.
Be carefull at there guys ;)
