How does a chronograph tachymeter work




















The racing watch design also features a stopwatch function, which can correspond with multiple chronometers for measuring times and distances. In addition to the chronometers, a racing watch includes a tachymeter on its bezel.

A less common complication featured on some racing watches is a pulsometer. This complication is designed for measuring the pulse of a driver. However, the pulsometer is not considered as much of a staple of the racing watch design as the tachymeter or chronometer. Racing watches have a unique appeal that reaches far beyond the world of competitive driving. These watches have a number of distinct features that can be useful for anyone measuring times, distances, and speeds.

The complications featured on a racing watch make this type of timepiece indispensable for use in a wide variety of competitive sports, from swimming and sprinting to eating contests. The chronograph has long been relied on in a host of contexts to measure elapsed time.

Interacting with a chronograph watch is uniquely satisfying. A well-built watch with useful complications can quickly become not just a favorite accessory but also a highly useful tool that comes in handy in a wide variety of situations. The chronograph on a racing watch can be used in many day-to-day circumstances, and its applications reach beyond the realm of driving and other competitive sports. In addition to being highly useful, a racing watch has a look that is a unique blend of classic and modern.

The stylish looks and numerous uses of a racing watch make it a worthy candidate for everyday wear. Racing watches can be paired with straps made from a wide variety of materials but tend to look best with a metal or leather band. Using quick-release watch straps , you can easily swap out the strap on a racing watch to transform its appearance. With multiple straps at your disposal, your racing watch can be right at home on a weekend drive, at a formal gathering, at the office, or anywhere else you may find yourself.

The versatile design of the racing watch makes it a jack-of-all-trades that is both stylish and practical. For automotive enthusiasts and casual commuters alike, racing watches have a lot to offer, and their looks and functionality set them apart from other types of timepieces. Older Post Newer Post.

The 1,piece limited edition Panerai Radiomi We live in an industry satura After stopping the chronograph, follow its hand to the tachymeter scale to obtain your speed measurement. For example, if the hand traveled to the second mark, the hand aligns with 80 on the tachymeter. This means the object was traveling either 80 miles per hour or 80 kilometers per hour. Method 2.

Find your watch's tachymeter scale at the 6-, 7-, or 9-second mark. Most tachymeter scales start at the 7-second mark, which is units of speed on the scale. Others start at 6 seconds and units of speed or 9 seconds and units of speed. The tachymeter scale is also located along the bezel, which is the groove that holds the watch cover. On some watches, it's also located just outside of the clock face. Be sure to note the number "60," which is the final number on all tachymeter scales.

Drive at a constant speed of at least 60 kilometers or miles per hour. Tachymeters don't run less than 60, meaning you can't measure distance if you're traveling less than 60 kilometers or miles per hour. For example, if you're driving on the highway at a constant speed, note your speed on the dashboard in either kilometers or miles per hour. Start the chronograph to begin measuring your distance. The chronograph is a stopwatch for analog watches that uses either its own hand or the seconds hand.

On most watches, it can be started and stopped by pressing the button at the 2 o'clock position on the watch. If you're measuring distance, you don't need two markers—all you need to do is travel a constant speed. Once you start the chronograph, all you need to do is wait until the chronograph hand hits the tachymeter value equal to your speed. This is typically accomplished by hitting the button at the 4 o'clock position on your watch. Determine distance when the chronograph hand hits the tachymeter value equal to your speed.

Once the chronograph hand reaches the value equal to your speed, you have traveled 1 unit of distance. For example, if your speed is 75 kilometers an hour, you have driven 1 kilometer once the chronograph hand hits the tachymeter value of If you're driving 70 miles an hour, you've driven 1 mile when your chronograph hand hits Multiply your initial speed by 2 if you're traveling less than 60 units of speed. Since the tachymeter runs until 60, lower speeds can't be directly measured.

To measure them, you must start by multiplying your speed by 2. For example, if you're traveling 40 kilometers per hour, 40 x 2 is Divide the final tachymeter distance reading by 2.

When you're calculating distance traveled at less than 60 units of speed, the initial speed is always doubled. This means you must always divide the final answer by two for the speed measurement. Consider the previous example: you're traveling 40 kilometers an hour.

If you double this number you get 80, which means you've traveled 1 kilometer when the chronograph hand hits
