Looking at a rusted mess. Many techniques to consider. How should I proceed?

Thank you for your advice

You can take it apart and place parts that can withstand that in a derusting solution of which there are many of various aggressiveness.
Realistically speaking chances that both modules will then work are very low. That even more if you don't have previous experience working on quartz module or watches at all. That we can't know since there was no introduction in your posting,  just the straight question.

It's always hard to say what to do with the rusted mass if we don't know what the mess is? What I mean is movement number would be helpful perhaps? Then it kinda looks like a separate movement in the middle with something around the outside which means maybe it's a modified standard movement which means finding a replacement movement is going to be problematic if not impossible.

I would tear the stem out and bin the movement. The steel parts in quartz movements will be toast by this stage and not worth your time trying to save.

As above, that movement is beyond saving, strip the watch and try to find a replacement movement and rebuild using original hands, dial and stem/crown..

Have you identified what the movement is yet?

Hi   Its a Harley/ronda movement and the state its in is BER,    care fully remove the movement and save the locking pieces and screws as you may need them for the replacement.  There should be a caliber number some where on the plates, Once that is known then a replacement unit sourced.  It goes without saying the case will need sone TLC before re fitting a movement.
