A7750 min/hour hand slightly move when chrono is engaged

[ck986]

I was wondering why the min/hour hand move when the chrono is engaged. Do you think this can be fixed with servicing? Is the movement loose in the case? Its very minor and my old portuguese would do the same. I am thinking of putting in a swiss ETA or just servicing the Asian movement if that will fix the problem. What do you guys think?

I think you have a modified movement. True A7750 has the configuration 12, 6, 9. If you hace another lay-out...the extra gears jump when you press the chrono button. No solution.
