Tachymeter scale watches are a prime example. This is a numerical scale printed around the edge of the dial or engraved on the bezel and allows you to measure your average speed compared to the known distance. You can technically use one on standard hours only, but for proper use requires the ability to start and stop time. Meanwhile, perhaps you also need to check out the popular seiko watch on the trusted online stores.
The 19th century watches with this scale are quite nicely documented. In the 1930s, several brands produced watches on a tachymeter scale, as well as two other main measurement scales that could be added to the chronograph: telemeters to measure distances and pulsometers to measure a patient’s heart rate.
Until the advent of digital calculators represented by Tachymeter, assuming the user could operate it quite accurately at 80mph. When the golden age of motor racing began, in the late 1950s, and the chronograph became a must-have sports watch (like Rolex Daytona), Tachymeter migrated to a steel bezel and took instrumental technical aesthetics that have been maintained ever since.
To this day, tachymeters have the power to make your chronograph feel more useful. And hopefully, when you finish reading this, your watch will be more than just a masculine ornament.
