Can anyone advise if every gasket "must" be changed during service on a Sub, or is it ok if only worn gaskets are changed and the watch passes pressure check? Reason I ask is that my local watchmaker, who is Rolex trained and certified, finished servicing mine...only replaced the case back gasket, and said the other gaskets were in excellent condition (pliable, well lubricated, etc.).
