As we outlined when we took a look at different types of bezel scales found on watches, a tachymeter is a scale on chronograph watches measuring speed and distance. It is found on the rehaut of the watch (just inside the dial from the bezel) or can be inscribed on the bezel itself.

Put simply, the tachymeter measures distance and speed. If you’d like to learn about the tachymeter in more detail, this guide will teach you all you need to know. What Is A Tachymeter For? Tachymeters are always found on chronograph watches. They can either be fixed to the case or they can be part of the rotating bezel.

Aug 26, 2024 · So, what is a tachymeter for on a watch? Well, a tachymeter, also called a tachometer, sits on the dial or bezel of a watch. It combines with the chronograph seconds hand to measure the speed of an object. With a tachymeter scale, you can measure speed based on time traveled over a fixed distance.

Dec 15, 2022 · 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.

The most common use of a tachymeter is for measuring the approximate speed of a vehicle over a known distance. e.g.) Based on how many seconds it takes a vehicle to travel 1km or 1 mile (the available measuring range is up to 60 seconds), the average speed within the …

Feb 7, 2025 · It’s a numerical scale either printed around the edge of the dial or engraved into the bezel and it lets you measure your average speed over a known distance. (They also...

Jun 5, 2017 · Just to clarify, all tachymeters are part of a chronograph watch, but not all chronograph watches have tachymeters. A tachymeter is a scale that may or may not appear on the face or bezel of a chronograph, which as we know is effectively a stopwatch. How does a tachymeter work?

To get an accurate measurement of your speed in miles per hour using your tachymeter, you need to know exactly how far you (or the object you are speed-tracking) have traveled. The easiest way to get an accurate tachymeter reading is to look for two points with a distance between them that you know.

Sep 16, 2021 · Tachymeter is a numerical bezel around the chronograph. It allows you to measure speed based on travel time and distance based on speed. A tachymeter is a versatile tool. You can measure distance or speed in statute miles, nautical miles, kilometers, and meters. There are also four types of tachymeter in the market.
