Continuity mistake: After Quinn bumps his head, he touches the wound with his left hand and his watch is turned around so the face looking inward. In the very next shot, from a different angle, he resumes touching his head but the watch has turned around to the standard position.
Chosen answer: Remember at first Quinn's timer is working perfectly (it's only because they slide off the ice age world early that it begins to malfunction) & given Quinn's intellect he would have devised a way that he could open a wormhole near him so he wouldn't be trapped on that world for 29 years.
