Whereas I have 'anorak' level knowledge of my subject matter, I admit to knowing very little about the exalted world of rare vintage Rolexes. This recent thread on TZ-UK is more than slightly off topic for this forum, but certainly worthy of mention. It concerns the auction sale of a frankened 'Paul Newman' Rolex Daytona Panda (worth approx. $100 - $150K) which was converted into a more desirable 'Sotto' Reverse Panda, potentially worth $1.1M.
The linked article FRANKEN/FAKE OYSTER “SOTTO” DAYTONA (RCO) AT CHRISTIE’S HONG KONG by an acknowledged vintage Rolex (and Panerai) expert Perezcope a.k.a. Jose Pereztroika (also on Instagram) which exposed this franken is absolutely superb reading, particularly in the astonishingly detailed level of proof provided. My hat's off to you, Sir !
