what was the experience of george when he woke up too early because his watch had stopped

George and J. wake up at six the next morning, and cannot get back to sleep. George tells J. a story about how he once forgot to wind his watch before going to bed, which left him confused when he woke at three in the morning. He only realized the mistake when he arrived at work, and aroused the suspicion of several constables as he walked around London so late at night.
