Morning guys,
For those who has had issues with power reserve on 4302 clone movement, good news.
That's my experience:
I got a fresh new 15500 v3 from a friend here on m2m.
It was never worn so seller didn't know how movement behaviour was.
When i received it i quickly noticed that after 12/14h it stopped tu run.
I tried to understand what the issue was than i realized that rotor didn't charge watch at all and manual winding charge was not sufficent to allow it to run over 12/14h.
As i really liked it because of the nice finishes and following some comments/advices here i sent it to a local watchmaker for a full service.
That were the readings of the watch when he received it:
It was clear that he needed a full service so...
Some shots of the process:
As you can see from the readings after service the behaviour of the movement changed dramatically.
What you see in the green circle are the weels dedicated to the autowind module.
He has to double clean them with ultrasonic bath as they were quite stucked and obviously responsible for the autowind charge issue.
As it's now in my watchwinder for almost a full week and considering that it's keeping run perfect...it seems that issue has been fixed.
AP is now also waterproof.
Special thanks to
@merlix for the great communication, kindness and precision demonstrated.
