How does the author use symbolism in the novel, War and Turpentine?

Urbain's golden pocket-watch, which is representative of memory passed down through generations, was initially given to him by his father, and he passed it down to his grandson, the narrator. For Urbain, the watch is a symbol of strength and responsibility, as it was given to him by his mother after his father's departure. That memory, however, is damaged when his grandson accidentally breaks the watch years later.
