Does Casio's New Calculator Watch Take You Back To 6th Grade Math Class? Slashdot reader jjslash brings word that Casio "has reintroduced its iconic calculator watch featuring a retro design with green text on a negative LCD and a classic keypad layout." TechSpot reports that the watch was based on the Casio Mini personal calculator first released in the early 1970s — even offering a keypad using the original fonts (with numbers separated by grid lines): Even the mode button, colored red, is a nod to the calculator's power indicator. The watches' calculator function can add, subtract, multiply, and divide up to eight digits. As for watch functions, you get dual time, an alarm, stopwatch functionality, and more... Casio's original personal calculator debuted in 1972, and cost $59.95. It featured a six-digit display, was a quarter the size of its competitors, and cost just a third of rival products. The calculator was an instant hit for Casio, selling a million units in the first 10 months on the market and more than six million units over the span of the series.
