But there is another cover inside. After seeing scratches where whoever serviced it had difficulty removing it, I didn't even try. It looks like there could be tiny pins at twelve o'clock and six o'clock, which would suggest a special tool may be needed to remove it. Photo of it does not show up in the preview. ???? Guess I don't know how to post more than one photo at a time.

Both of the local watch repair shops in our little town seem hesitant to do anything at all to it and the nearest JLC service center is about 300 miles away. So ANY info, help, tips, suggestions, etc. that any of you could provide would be greatly appreciated, as is your time.
Sincerely,
