got this today was hard to get a hold of! dont know if I will continue with the project or not, as I have spent too much money already... the movement is simnply gorgeous! EXACTLY the one Rolex used in the Vintage Panerai (notice that theres no jewel on the Hour wheel, exactly as it was with the movements Rolex used in the Panerai watches...also the regulator is the exact same as in the proginal Vintage Pannys!!)... Cortbert produced the movements and Rolex bought them and put their name on it, so ALL of them ,even those in Panerais which are Rolex signed, are in fact Cortbert!
