The fact that Rolex aren't keen to have their insides bared for all the world to see would make it THAT MUCH MORE INTERESTING to have a forum in which people actually care about the insides of these watches and are willing to take the cases off their vintage models so we can see the evolution of these movements over the decades. (Daytona, anyone?) These are spectacularly accurate and durable movements, and it's anomalous that a website devoted to horology has neglected them so utterly.
