The man in this episode, played by Ed Wynn, is obsessed with death. He connects his mortality to a Grandfather's clock. He believes that when the clock stops, that will be all for him. The episode is a continuous portrayal of his fixations on the clock. When he needs to get rid of it he must have guarantees as to its treatment. Wynn plays the frenetic old fellow, using his strange voice and intonation for a nearly comedic presentation. He is really paranoid and perhaps mentally ill. He needs to know but he doesn't. In the end, the Twilight Zone fixes things up. We could say it's like clockwork. It's an OK episode because of the performance, and it is nice to see how things turn out.
