Retro Deal: $17 Casio Calculator Watch
By James Grahame
Yes, it's geeky. It's also incredibly useful. The $16.45 Casio CA53W-1 calculator watch includes an 8-digit calculator, dual time zones, stopwatch, alarm, 5 year battery and automatic perpetual calendar. There's no backlight, but I suspect that's how Casio is able to keep the price so low.
