My order# is T44228. The watch runs fine when upright (12 on top), but if it is on the wrist or otherwise in an inverted position (12 pointing toward the ground), within a few minutes the balance wheel comes to a full stop, even when the watch is fully wound. It may take anywhere from one to fifteen minutes for the stop to happen, but it always does, and so it cannot reliably keep time. If kept fixed with 12 on top, it can run for days without stopping. Please repair/replace. A Youtube video of my watch demonstrating the problem may be seen at:
