While we may have clocks posted throughout towns, mobile phones in our pockets, and wrist watches to give us the time of day, people still ask, “What time is it?” on occasion. It doesn’t necessarily grind my gears so to speak, but it is a tad annoying. If you want to tell someone the time without actually giving them the satisfaction of being able to read it, then do I have a watch for you!

The Equation Watch won’t have you saying a number outright, as you’ll be presenting it in the form of a math problem. You’ll be able to give out answers like, “Oh it’s around 486 divided by 54!” If you had any disdain for those whippersnappers that constantly ask the time when it’s right under their nose, then this will make them disappear right quick. For $30, this is a fun gift for the math lover in your life, or a good way to confuse anyone who dares peek at your timepiece.
