Mechanical “digital” watches were all the rage just before the advent of the true, digitial LCD watch. This watch, complete with wee helmet, is the best of that hearty breed and is actually quite rare. Notice that the movement is built “up” and not flat and how the helmet fits the whole thing perfectly. That’s a sign that the designers were actually thinking about what they were doing as opposed to saying “Let’s put a helmet on this thing and go get lunch.”

Apparently this is one of the the only two in known existence. It’s the chupacabra of watches.
