As a watch specially designed for movement, timekeeping functionality is key. There are a tachymeter around the rim of many sports watches, which is used to calculate an average speed between two distances. It is so convenient to figure out how fast you're running or how quickly you are riding in Per unit time. This feature is so important for runners and sailors. In 1963, the Rolex launched the Rolex daytona which was specially designed for racing driver. The watch is equipped with a chronograph function and a tachymeter scale. The Rolex daytona replica can calculate the speed of racing and recorded the brilliant achievements of racing track, and it has achieved iconic status, and become the world's most famous and most respected timing wrist watch.

Plus, a sports watch is clearly telling the time with its luminescent dials. Luminescent dials are relevant for reading the dial in the dark- particularly underwater. All divers watches must be equipped with a luminescent dial. You can see the time advantageously wherever you go, even in the extremely black place. Whether diving, working at night, there's nothing more reassuring than the luminous dial of a watch. You don't need to find a light, just glance at your wrist and you know exactly what time it is. The luminescent watch face and hands is just one of the great features of high quality sports watches.

Of course, water resistance is a another key function for a sports watch. Water resistance is generally measured by the depth of water the watch can be immersed. A sports watch is really water resistance to meet your demands. Rolex Submariner is one of the best diving watches, which is water resistant down to 300 meters; And the Rolex Sea-Dweller is the ultimate divers watch collection, which is water resistant to 3,900 meters/12,800 feet.
