My BB58 bezel was a hair off center so I took it apart and fixed it. I also was curious about how it locked in a bit tighter in the 12:00 position. I thought I would share some pictures of the watch with the bezel off/apart. Makes me want a BB36 with this dial. Note - I tend to impulsively try to fix things that might ought to be dealt with by professionals. I am not a watch mechanic. Please do not use my pictures as instructions on how to do this. I did a small amount of aesthetic damage to the case and am probably lucky I didn't break the insert.
