How do you open the back of a AWW Co Waltham Mass key wind pocket watch to view the serial number if you do not have the key?

Answer 1

Place the watch face down in the palm of your left hand. Place the palm of your right hand on back of the watch. Push palms together and turn right hand counter-clockwise. Clock back should screw off. I have one watch like that, but this watch has hinges. I can get the first part open, but not the next layer to view the movement. Thanks for trying to help!
