What am I doing wrong? I can’t seem to remove an 1888 movement from its case. I have two watches that I’m swapping cases — I loosened the screw (photo above) and was able to remove the stem easily for this movement; however, loosening the screw on the second movement isn’t releasing the stem. The stem does become more loose and I’m able to move it up and down a little but it won’t disengage. Any ideas what I can do?
Also, can I swap out an oxidized crown wheel on an 1888 without disassembling the whole movement and letting down the mainspring? Are the crown wheels the same on OF and HC 1888 movements?
Thanks for your help.
