Guys, I received the screws, they're holding the CG perfectly!!! It's all about the cheap screws, they're losing threads.. the case and the holes are OK!!!
The new screws? Not loose, not tight, right on spot. Perfect grooves...They're made for it!!!
Finally my 111H is back on my wrist.
For the reference, it's an Angus - Ultimate 111H case and CG that I bought almost a year ago.
