AliX sub case spacer for NH movement

Cheap AliX watch cases that 'claim' to fit S-brand/TMI NH series watch movements never fit properly. This spacer makes sure the movement does not rattle around in the case. It's a tight fit, you need to gently work the spacer into the gap between the movement and the case, starting from the crown tube opening, and working your way all around until it is fully seated.
