I was watching an older Bond Movie with Brosnan. In one scene he and a Chinese lady-agent are gearing up for a mission at her hideout. Bond picks out various items from her collection - weapons, gear, etc.
At one point he takes a watch (SMP) and shows it to her:
Bond: This looks familiar
Chinese Agent: We've made improvements
(Bons smirks, puts the watch in his shirtpocket)
Later Bond uses the watch as an explosive device with a detonator. Which made me think that the actual watch Bond uses must have a thin Quartz movment to allow for the space to house all the junk. Which is kind of ironic.
