It's gold plated but in decent shape. I wanted to try out a bumper movement and was curious about the calibre.Some 1960s watches are designed to have the movement removed from the front. Have a 1960s Benrus that needs the crystal removed to access the movement. Hope this helps.
That Omega is nice looking, is it solid gold? With a polish on the crystal, it will be a cracker of a watch!
Thanks.Razer blade was good idea as it worked perfectly. The caseback snaps tightly.Should be able to get a razor blade in there and work it around. Start stacking them if needed. Use single sided for safety.
