The past two times I've worn my '56 Hammy K-455, it has stopped on my wrist. This is frustrating because all the other times I've worn it this hasn't occurred. Granted, both times I haven't been moving much (studying for finals) and I simply shook it to get it going before I put it on. It has the Hamilton 661 movement (which is actually a Kurth Freres 28.45). Does the rotor only spin in one direction?
Is this just a lack of getting the watch going? I prefer not to manually wind it. The watch was serviced near the end of last year, so no issues there.
Everything is probably a-okay, but I figured I'd ask.
