After his death, Martha gave the watch to Clark, saying Jonathan would have wanted him to have it. However, Clark rejected it, because he felt responsible for his father's death.
Soon afterward, the watch was stolen from Martha by gang members in Metropolis. Learning of this, Clark regretted not having taken the watch, and vowed to retrieve it. With the help of Andrea Rojas, Clark found those responsible for the theft, but they had already pawned it. Lana Lang searched every pawn shop until she found it and restored it to Clark.
Clark is shocked to discover that the assassin attacking him is wearing his father's watch... set one year in the future. She tells him that Clark gave it to her himself.
