Still working on the BW Raymond. It's together and running but it has a strange noise I've never heard before. I've heard a hairspring rubbing before. That's a quick metallic "shushing" noise. I've heard the pallets clicking too but this noise is a new one for me. It's a "2-tone" like something being plucked in and out. Very similar in sound to the teeth on a hair comb being plucked twice in a row very fast. So it's a "dink-dink" noise. Shows up pendant right or left and goes away dial up or down and amplitude drops off when it's banging. Obviously, something is shifting enough to hit and tap something else but I don't know what except maybe the guard pin on the fork. Other than that, I've no idea what it could be so any help is appreciated.
