If the 311.30.42.30.01.005 is the current, standard Moonwatch, with the big black box, the answer's yes. The watch head is the same and the bracelet is different only insofar as it has screws in the removable links. AFAIK the removable links are even interchangeable as the pin, which is held by the screws, is the same diameter as the sleeve in the older bracelet.
