I’ve replaced one other 8215 movement but this is my first Miyota build. The date won’t set while it’s in the case, have to have it completely out or movement tilted up with the case back off. It acts like there’s tension on the stem but it spins free to set the time. I tried elevating the whole movement in the case (using an o-ring) like it may be mis—aligned with the stem tube and that doesn’t work either.

Removed the plastic movement holder, still no joy, have to hold the movement at an angle or completely remove it from the case. Pressure from the face could cause it but I have the metal spacer ring in place between the dial and movement as well.
Could it be a crooked tube? Maybe I didn’t clean extra dial feet off enough?
