The Mosquito Repeller Watch

A new wristwatch that supposedly can repel mosquitoes. How? By emitting the same ultrasonic high-frequency sound made by an approaching male mosquito. Normally we wouldn't think that that would do the trick, but it turns out that it's pregnant female mosquitoes who do all that biting and that they really don't like male mosquitoes. Bonus points for the watch having bad Eighties styling.
