Oh, I got one that does that...The Miyota 9015 28,800 BPH automatic in my Lum-Tec M50 winds in only one direction and I thought it was broken too!The Valjoux 7750 only winds while the rotor is spinning in one direction, and if it free spins fast enough in the other direction the wobble occurs. If you like that feeling, you'll probably enjoy wearing bumpers.
yea i have found that out the hard way, still mulling over my next big watch purchase, its not easy guess there are alot i likeForget it, bub!
Once you come to the realization you want everything, it's already too late.
Just accept fate and keep checking the want ads for a second job.
