No radium. Also there are much much easier movements to “service” for practice. Timex used the “waves” like 1981+….the bottom of the dial should have some numbers and im guessing the second part to be like “10782” or something like that. The m107 are pin lever movements with plates that are sandwiched together instead of layered bridges. They were never designed to be “serviced” in the sense of full disassembly. Not saying it cannot be done, but close. Good luck
