    Morning Community:
    I found a shop that can repair the case back of my watch but I need to send the entire case as well. Can't figure out how to take out the crown stem to take out the movement. I don't see any holes/pins like some watches where you need to do is push while pulling out the crown. Guidance please? Thanks.

    You need to loosen the stem release screw, but just enough to remove the stem. Not too much. If you mess it up, you're going to be unhappy.

    My feeling is that if you don't have experience with this, you'd be better off letting the shop do it. What's the big risk in shipping the whole watch? If the case and case-back are lost in the mail, you're pretty much out of luck anyway.

    That is so true. Didn't think of that that way. The shop(Asia) uses a courier here in Oregon (don't ask me why) then from Oregon to him. Maybe he doesn't trust this courier with a complete watch(lol)? Which one is the stem screw? I can do it. It is just that I am so used with Seiko. Thanks Dan

    It's important that you only unscrew it enough to remove the stem. Don't go crazy unscrewing it multiple turns. Be gentle and slow.

    Try to pull the crown out every screw turn?

    Less than one turn. You might start with one turn, or one and a half. But if that doesn't release it, I would go half a turn from there.

    You made me laugh when you asked where the crown screw was. :D

    I know. I wasn't going to be the one to take responsibility for giving that answer. But once he seemed determined to try it, I thought I'd try to help. That thread I posted has advice from watchmakers.
