A watch produced by the Casio corporation, it has the capabilities of early pocket organizers. It includes 150 memory slots to hold telephone numbers, keyword notes, and appointments. It also features a calculator, world time database, alarm, timer, and stopwatch. It has protected memory, and comes with a calculator-style keypad and Illuminator piezoelectric backlight.

I have owned one of these watches for over 5 years, and it has never let me down. I still have the original information intact, after 2 battery changes. The only thing I would fault was the band, which went after 2 years, but it's still the best watch I've ever owned.
