I want to change the dial of my HBB, and after some googling I find no such tutorial anywhere. So I turn here.
I have an H screwdriver and a set of small precision screwdrivers.
I just discovered that the "1" marker on the 12 is loose. Is there any way I can fix this by myself or should I hand it in for repair. The hands are also not perfectly aligned, they need a tweaking.
