A good feedback is very important to us. The tachymeter bezel is the distinguishing feature on iconic chronographs like the Omega Speedmaster and Rolex Daytona.The logarithmic scale is proportional to one over elapsed time (1/elapsed time) and therefore is used to measure units per time increments. Most common of these is speed in miles per hour. However, you can also calculate units per hour on a production line, pitches per hour during a baseball game, or the average rate of any other repeating event.
Start the chronograph when one unit passes (mile marker, widget, whatever), stop it when the next unit passes, and read units per hour on the scale. In short: nice classic chronograph, in very good condition and...
