Watch functions and analysis(2)
Today, I will continue to bring you four useful analysis about watches, let's go.
Dual Time Zone
Dual time zone watch definition:For analog watches, there are two adjustable hour hands, one hand indicates the local (first time zone) time, and the other hand indicates the time in the second time zone.
Single Rotating Bezel
Diving watches are generally equipped with an irreversible clockwise bezel. In addition to the modern concept of decoration and a symbol of sports life, the bumps on the bezel and easy-to-read numbers allow the wearer to accurately adjust the diving and sports time. Absolutely reliable. The outer ring only rotates in one direction,even if it is accidentally rotated, the remaining movement time will only be shortened to ensure safety. Generally, it is rotated in one direction to a certain scale.The purpose of non-counterclockwise rotation is to allow the diver to determine the time for the oxygen consumption and return to the surface according to the instructions of the watch.
Speed measurement
Commonly, the outer ring of a watch with a stopwatch function will be engraved with successively decreasing numbers such as 500/400/350. The physical quantities represented by these are hours, and the unit is km/h. This bezel is called a tachymeter, which can measure a car at a fixed average speed of one kilometer or one mile. Taking the method of measuring vehicle speed as an example, when the car moves forward with the mileage mark on the roadside as the reference point, the timer is activated. When the car reaches the next mileage mark, The position where the timer pointer rests on the speedometer scale is the speed of the car. If it takes 45 seconds to reach 1000 meters, it can be converted to a speed of 80 kilometers per hour.
