I'm just looking for some insight into the quality of this movement. I'm looking at an otherwise very well built micro brand watch for $350, used, and have heard less than stellar feedback on this movement. Apparently the second hand stops if you shake it, but this doesn't effect accuracy? This watch also has a display back, which may not be terribly appropriate for this movement? I've had several ETA and Miyota driven autos, and even a vintage Standard Time driven watch, and it's never really made much difference in actual use, but I feel the cost of the watches was appropriate to the movement.
