THE SMART TRICK OF ROLEX AAAROLEX AAA THAT NO ONE IS DISCUSSING

This movement has pretty low high quality ending. The hairpspring is mounted counter clockwise. Prevent this motion if at all possible. There is also a no-day Model of the movement called the SH3130 (or often the AR3130) and that is of in the same way bad good quality.This is another clone of the ETA movement that isn't located inside a real Rolex.
