Torgoen has developed a pretty nifty watch, if you were born before the 50s and also had a stint at NASA. The Pilot Watch with Slide Rule features a circular slide rule that is “useful for units of measure conversions and multiplication/division problems” as well as for calculating time, distance and speed. Or you could SMS Google with your request and have an answer back in less time than it takes to spin your new watch. If you’re the patient, curious type though, Think Geek has the watch for $250.00 and includes instructions for using the slide rule.
(Edit: So when I mentioned Google SMSing, I forgot entirely this is supposed to be a “Pilot Watch”, as reader Mark R. reminded us that it’s illegal to do from the cockpit anyway. He goes on to explain the usefulness of such a watch for pilots:
The “slide rule” on the watch is basically what pilots call an E6B flight computer, or a “Whiz Wheel.” … It’s used for making in-flight calculations. … The whiz wheel is handy because you set the relationship between the scales once, and can read various values off the wheel as conditions of flight change.
You learn something new every day!)
