Watches with Tachymeters: How They Work and Our 15 Top Tachymeter Watc
It's a common refrain in the watch collector community that chronographs are one of the most popular complications while at the same time being one of the least practical in day-to-day life. Many of the most famous chronograph watches are also equipped with tachymeter scales, and while fans of these watches mostly agree that they look very cool, few of them have ever used the scale with the stopwatch function, and many wouldn't really know how. Nevertheless, the tachymeter on a watch was invented for a utilitarian, practical purpose once upon a time and it's worth briefly exploring those origins and exploring those capabilities. Essentially, a tachymeter (also called a tachometer) is a numerical scale on a watch’s dial or bezel that is used in conjunction with a chronograph seconds hand to measure an object’s speed over a predetermined distance. It is often used to determine miles or kilometers per hour and is thus a common feature of chronograph watches whose design is inspired by automobile racing; we'll showcase several icons of that category in our list below. Unlike divers’ watch bezels, which should rotate in one direction to set dive times, or other types of bezel scales used for calculations and conversions, like the circular slide rule on Breitling’s Navitimer, most of which are bidirectional, a tachymeter scale bezel should be fixed. The numerical scale typically starts around the 6- or 7-second marker on the minute track, and is usually indicated in ...
