Disassemble and re-assemble Ronda 763

[LittleWatchShop]

I ordered a replacement movement on ebay for under $10, but was curious if I could service this tiny thing.  Three wheels fell in place readily using my normal eye loupe. However, that little rotor was a pain so I had to move to the microscope to finish the job.  The picture shown is the movement I bought...not the one on the bench.

This is my hobby of course--I doubt this would be worth the effort as a professional where time is money.

These are sold as repairable movements but as you say the replacement cost is cheaper than repairing them.
