Jesse Pinkman gives Walter White a TAG Heuer Monaco chronograph watch as a birthday present. Walter later shows the watch to Skyler White, saying that the person who gave it to him once tried to kill him and therefore it's evidence that Skyler will change her mind about him, too. Walt then goes to sleep, and the scene closes with a close-up on the watch ticking, indicating that Walt's time is coming to an end ("Fifty-One"). After making the call to get Schwarz's address, Walt leaves his watch on top of the payphone ("Felina").
