The Spy-watch Who Loved Me - 1955 Protona Minifon P55 Recorder Wristwatch
No, this isn't a prop from Dr. No, this is a true blue (or pinko) Cold War Protona Minifon P55 recording chronograph. The watch had no movement, just a microphone shell and disguise to the recorder unit. Problem is, it's a large unit... You gotta bring the Protona carrying case along too, maybe pretend you're on your way to Idlewild airport.
Originally sold for $350 in 1955, there are a few sets available online now for around $1000.
