It's been years since my last post.

Last year I installed a fresh new 4r36 from Japan in my Seiko Monster (yeah I still love it, wear it 24/7)
I was replacing an NH36 that I'd had in it for a few years.

My frustration is that after I calibrate it to <+/-10sec/ day and <.5ms beat error, when I put the caseback on, the accuracy starts to drift. Then when I cinch it down it's off by 30sec or more. The beat error stays accurate.
Can anybody explain this and tell me what I can do?
Thanks
