Mini Analog Pocket Watch Gun

This probably wouldn’t be the best thing to bring aboard an airplane. You’d either get arrested, or people wouldn’t be able to stop laughing at you, so it’s a lose-lose scenario. It seems like some nostalgic person missing the “good old days”, took the time to take apart this analog pocket watch, and replace its guts with a 3mm gun. The watch obviously doesn’t show the (correct) time anymore, but it might be comforting to know that you have a tiny gun in your pocket, just in case a kitten tries to scratch you or something.
