Minor update
Gen cannon pinion/minute making big improvement in performance and amplitude of the movement
Also I tried gen barrel bridge - fits and working perfectly
Gen Train bridge fits ok but movement lost performance
When you replace a balance wheel have to replace pallet fork as well
You adding about $800 and you still have yuki movement
The only parts need to be replace is a keyless mechanism and Swiss mainspring, good bath, proper oiling and the movement is working better then gen one (better amplitude and faster timing adjustment)
Only my 2cents
