Remember those Casio and Timex watches back in the day that weren’t only digital, but also had calculators on them? Well apparently there is still some interest in them because over at Curiosite it is back. This is understandably not the same retro look or quality as its predecessor, but it’s still cool in its own way. The Retro Calculator Watch displays hours, minutes, seconds, as well as the month, date, and year. You”ll also be able to calculate square roots, divide, multiple, etc…And most likely teachers won’t even notice it, because they will be looking to make sure just that your iPhone or Blackberry is put away during a test. The Cal-Q-Tek 2000 retails for $17.72.
