Anyone ever change one before? I read on Amazon that you're supposed to take them to a dealer, but do you really have to?

    I take mine to any watch shop because of the tool needed to remove the back. I think I paid about $6 for replacement. (I think since I bought the battery there they replaced it for free)..

    It appears to need a small screwdriver, which I have. I thought I might mess up something on the inside. I guess I could just unscrew the back and look at it.
