Yes, the modules in these two watches are (theoretically) interchangeable. There is no guarantee, though, that the display and setting functions will work properly, due to potential mismatches between the button magnet strengths and reed switch sensitivities. A function may activate and not shut off, or not come on at all. It might be necessary to adjust or replace one or more switches to get the module to operate correctly in a different case (Time Computer had this same problem...their solution was to simply have a large stock of modules they could try until they found a compatible one...an option we no longer have). It's just something to keep in mind when shopping for a replacement module (for any but the Touch-Command or Calculator models).
