Okay guys, so I just picked up a 1961 Omega from a friend of mine (no pics yet, and technical information upcoming). I have a great strap that I'd like to put on it, but can't for the life of me get the old one off. I know I'm not giving you a lot of information here, but are vintage omega spring bars lacking a ridge (or shoulder) to make it easy to remove them? I cannot find my loupe, but I do have the right tools, but the spring bar won't budge. I'd hate to run to the watch shop, but may need to unless one of you knows the "secret." Thanks for any ideas.
