As we know this is a cheap simple time piece, but even simple pieces can be broken to a point it can not be fixed. Please make sure you have de-energized the watch before proceeding.
1. Remove hour hand gear. This gear is not held in by anything and is easily lost if left to it's own devices.
2. Turn over. Remove case retainer clips.
3. Remove main spring plate. If you have not de energized the watch, you will have a surprise now as the spring can leap out at you.
4. Remove main spring assembly. This will drop/release a large gear on the face side of the movement.
5. Remove last screw and movement cover plate. Take care, the balance wheel and spring are attached. This movement uses a more stout balance spring, but it still can be damaged if not handled properly.
6. Tray the rest of the loose parts. (gear train, escapement, fob lever, and fob cog.)
7. Do not try to remove other face side parts. They are rivetted in.
That completes the breakdown. Check your parts. If you misplace a part now you will not have it later when you try to rebuild.
Now it is time to clean. I will not be going through this step by step. I probably do things that would make most cringe, but then this watch is badly corroded and I will be using some strong chemicals to try and restore the metals.
