I feel your pain brother.
I am having the same troubles getting it perfect. I have it where I can live with it now, but I am far too picky to not bust his sucker open and try again one day. It took me damn near a full day to get it like it is, so I gave up.
I used GS Hypo cement and you can move it a bit but you have to hurry. I only used a few drops.
Pug,
I have tried to place the date wheel on the overlay, but so much overlay hangs over I cant get the datewheel back on the movement. The little piece that you must push back to get it into the notch of the date wheel cant be seen with an overlay over it.. I hope that makes sense. If you know how to do this, please share.
