Oh boy, I remember calculator watches. With all the fancy handheld gadgetry today, there's really no reason for them, though even back in their heyday they didn't really set the world on fire.
That's not what the Cal-Q-Tek 2000 is banking on, anyway. It knows that no one uses calculator watches anymore — it just wants to cash in on that retro style. And cash in it does, because I find myself strangely wanting one. You can get one yourself for a cool $18.
