Move over, Casio Databank (and similar) -- a formidable opponent just rolled into the ring. While the aforementioned timepiece has been the geek watch of choice for years now, Jennings' WatchScale is all set to give it a real run for the money. This wristwatch not only displays the time in brilliantly blue fashion, but it also weighs lightweight objects (up to 300-grams) with an accuracy of 0.1-grams. We know, you're already bracing for a quadruple-digit (pre-decimal) price tag, but there's no need for worry -- after all, you can procure your own for just $17.90.
