How do you use a tachyometer on a wristwatch?
warthogmadman987 asked:
You somehow correlate it with the chronometer to find your speed, starting the chronometer at your startpoint, and ending at your endpoint. So from that, how do i read howfast i was going? Why does the bezel rotate? And since thi bezel moves, were do you put it to read the correct speed?

speed reading
Start the bezel at 12:00 straight up. Then you make a standard calculation. Distance divided by time = speed expressed in a ratio. Example: 1 mile in 12 minutes = 1/12 common denominator: 5×12=60, 1×5=5, therefore 5/60= 5 miles an hour. Good Luck!
