Every Hamilton watch presence in a film is the result of a close working relationship with filmmakers. Collaborations range from developing a custom prop watch to making watches available from the current collection to sourcing historical timepieces that fit the period of the film. In every instance, each carefully chosen or created watch serves to define both the character and the filmmaker’s vision. Hamilton watches figure prominently into the story of Christopher Nolan’s Oppenheimer, from Universal Pictures, in theaters July 21, 2023. Sourcing the watches themselves, however, was no easy task.
