The Radar Watch from Alexey Bykov is a timepiece fit for a submarine commander. This watch uses a mock radar to tell time and detect enemy ships and aircraft.
Okay, so maybe it can't actually detect planes and ships, but the Radar Watch is still badass nonetheless. The watch is split into four coordinates, each representing quarters of an hour. The radar "scans" the watch and plots the time accordingly. This watch would make a cool gift or novelty item. Make it happen, Alexey Bykov!
