TACHYMETRE Tiffany Blue 42.5MM

The Serket Tachymetre is a meca-quartz powered chronograph watch with cutting  edge style. This racing themed chronograph watch will exude a real presence on your wrist.  A tachymeter is a specialized watch feature that relies on a scale inscribed around the outside rim of a watch, either as part of the rotating bezel or fixed on the watch case.  A tachymeter can be used to calculate speed based on travel time or to measure distance relative to speed. One of the biggest benefits of using a tachymeter is that its functionality is independent of any unit of distance, so long as you stick to the same unit of length for your calculations. In simpler terms, a tachymeter can be used for calculating miles, kilometers, meters, or other units per hour. It can also measure the frequency of a regularly occurring event in occurrences per hour.  Essentially, a tachymeter is a tool that allows the watch wearer to convert elapsed time (seconds per unit) to speed/rate (units per hour).
