wait so let me get this straight, the hour and minute doesn't move when you try to do a manual sync? And they failed to move in regular time keeping as well?
I usually would try to remove the battery, wait maybe 5 to 10 min, then reinsert the battery again. Or try another brand new battery. But the 1666 movement does have a low battery indicator (which the 2nd hand jump every 5 sec). So I kinda doubt its the battery itself.
just to give you an idea, Omega will replace the movement for $500, and I think it would be the latest 1666C SQ movement.
