Butch Jenkins risks his life for his father's gold watch because the heirloom represents his entire identity, his family lineage, and his personal honor. The watch is not just a valuable piece of jewelry; it is a sacred relic of intergenerational trauma and survival, as established in the lengthy prologue where Captain Koons explains its history to a young Butch. The story of the watch surviving two world wars and a Vietnamese prisoner-of-war camp defines Butch's understanding of manhood and legacy. To leave the watch behind would be to abandon his ancestors and accept the narrative that he is merely a cowardly, bought-and-paid-for boxer who ran away with Marsellus's money. Structurally, this choice serves as the inciting incident for the second half of his story. It forces Butch out of his safe domestic bubble with Fabienne and back into the dangerous, unpredictable underworld of Los Angeles. This decision leads directly to his fateful encounter with Vincent Vega in his kitchen and his subsequent run-in with Marsellus Wallace on the street. By prioritizing this symbol of honor over his immediate physical safety, Butch sets off a chain of events that ultimately allows him to redeem himself by saving his enemy, Marsellus, from the basement of the pawnshop.
