Are you asking how it comes apart as part of your planned restoration or to get it off the wall? It's probably not bolted/screwed through. These clocks had inverted "V" hangers on the back and usually just lift up and off. Once you get the electrical conduit disconnected, you shouldn't have to take it apart any further to get it off the wall. If you're asking for restoration purposes, the above comments are spot on...I'll only add that the hands then come off with simple large nuts and the face lifts out to give access to the mechanism. Good luck!! Cool Clock.
