He is wearing sunglasses and turns his head so you can see his ear for about 5 seconds. Approximately 15:03 into the episode.
Monroe is seen working on a clock using a cheap imported "third hand" tool with a built-in magnifying glass. That is what schoolboys use for soldering but not a preferred tool of high-end clock-makers.
