No, that is correct. The Accutron has a predictable position error, gaining or loosing a couple of seconds a day depending on whether the tines of the fork are pointing up or down. (gravity effects!). They are calibrated depending on whether it is worn on the inside or outside of the wrist, or whether on the left or right arm. He was simply taking advantage of this phenomenon to make it gain or loose without having to reset it. (on the original 214's there was no hack mechanism to start and stop the movement without taking the battery out). When the watch is worn, it's temperature is maintained at very close to body temperature, in effect it's own "oven".
