I just picked up a sweet little Waltham on the Bay for about 10 bucks. I think it's 1960's or thereabouts. Never had one of these before but for the price decided what the heck.
Its throwing up fairly decent numbers but running a bit fast and I'd like to try regulating it.
However, for the life of me I can't figure out how to open it up. I assume it's a snap back but I can't find any notch, and my effort have been unsuccessful. Doesn't seem to want to screw off either.
Anyone know how to crack these open? Thanks!
