What are the popular science we need to know about watches? Here are some basic knowledge of traditional watches.
1. The style and function of the watch
The style and function of the watch are divided into two categories: mechanical and quartz. The most common mechanical watch has an automatic calendar function.
2. Quartz watch and mechanical watch
Which is better between quartz watches and mechanical watches? There should be good and bad, regardless of value, and quartz watches are also expensive. Mechanical watches are also cheap. Generally speaking, mechanical watches are more ornamental, while quartz watches have high precision and are easy to use. To distinguish them, there are 3 ways：(1) Look at the logo, the automatic watch will have AUTOMATIC letters, or SELF-WINDING letters, (2) Look at the movement of the second hand. It is a quartz watch that jumps every second, and a mechanical watch is the second hand that continuously crosses the dial. (3) Whether it can be wound or has the sound of automatic rotor rotation.
3. The indication function of the watch
The hands and dial cooperate to indicate the time, and there are also windows that use numbers. Windowed are mostly used for calendars. The so-called "big calendar" is two windows that display the tens and digits of the date respectively.
4. Flyback and retrograde forms of watch hands
Instead of circling clockwise, flyback is the characteristic of the chronograph returning to zero, while retrograde is the "fan shape" of the hands. The fan-shaped retrograde is weird, it automatically returns to zero after the full distance.
5. Chronograph function watch
Commonly known as "three needles and three eyes", it also has 3 crowns at the same time. 1. Most of the chronographs currently use a two-button type, and the two buttons are usually at the 2nd and 4th o'clock positions.The 2 o'clock bearing button controls the "start and stop" function, and the 4 o'clock bearing button controls the "zero" function.2. The operation method used is usually the process of "starting---stopping---returning to zero" or "starting---stopping---starting---stopping---returning to zero". The stopwatch function must be stopped before pressing the reset button. 3. The single-button stopwatch is relatively simple, and the function of "start-stop-return to zero" is controlled by one button. Please note that every time you press the button, you must wait for the button to reset before you can press it a second time.
