Vintage MCM Sheffield Pocket Watch

I cannot get this case open. Wear to finish. Does not run.

I sell all my watches AS IS, For Parts or repair. Even if I say it is running I do not guarantee it to arrive that way. Why? Because shipping is hard on watches and can very easily change the condition of the watch. There may also be underlying issues with the watch that I am not aware of as I do not work on, repair or diagnosis watch issues. I do not guarantee them to be complete or to have all original parts. Again, you are buying this for parts or repair. There is absolutely no reason I should be contacted for a return or an issue regarding the condition of the watch. You are responsible for servicing and repairing any issues if you purchase. Bid accordingly.
