There are three subdials in the watch, which are chronographs, and its main function is for timekeeping.
The six o'clock position is the conventional small seconds dial, the three o'clock position and the nine o'clock position of the two small dials are respectively counted 30 minutes and 12 hours, the large second hand is the chronograph second hand, usually do not open the chronograph button, the chronograph second hand is not gone, the chronograph second hand is 60 seconds, the 30-minute disc goes a grid, the 30-minute disc goes two times, the 12-hour disc goes a grid, and so on.
-
In fact, in this structure, the three small circles in each represent an hour hand, a second hand, and a minute hand.
-
The three small circles inside represent the week, month and calendar.
-
In this case, it represents its basic model, so it is important to note that in this regard, it means a gear.
-
This is generally a second hand and a chronograph function, if you don't understand, you can take a look at the manual.
-
This small circle must represent a very important meaning, so it is usually very important, in this case it is better to find some technical staff to see what it means.
-
This circle you are talking about is the battery inside it.
-
If you want to see the structure inside this watch, and if you are following the prototype over there, you are looking up the mechanical structure of his people, so you can check the internal structure of it according to this.
-
If the ribs are three small circles are represented by three adjustments to the time structure.
-
My cousin and I are juxtaposed with the three little rounds, I don't know about this, and I don't know if this Xiao Yuan doesn't represent the seedlings or something, it is possible that he follows the table like this.
-
The structure of the watch is actually very different, of course, the function is almost the same, and the small circle inside also has many different meanings.
-
Inside the structure of this model of the watch is that there are three small circles.
-
As for the structure of the watch, it is still good to be side by side.
-
The structure of this model of the watch K6003M has three small circles inside.
-
Surely the watch can be 6003m results and divided into small circles inside, representing his.
-
Find the structure. Why? I don't feel normal if it's not too much.

Popularization of watch knowledge: Usually the watch panel or back cover is marked as Quartz or Automatic, so you can clearly distinguish which is a quartz watch or an automatic watch. Another way to identify is to look at the way the second hand of the watch moves, if the second hand is a leap second by second, then this watch is a quartz watch; On the other hand, if it is not a jumping walk, it is a mechanical watch.
If you find that the second hand travels for two or four seconds at a time, this is still a quartz watch, and when this phenomenon occurs, it is to inform you that the watch in your hand now needs to replace the battery, because some of the better designed quartz watches have this device, and will walk one at a time.
Four or five seconds to let you know in advance that it's time to replace the battery. A brief introduction to the method of distinguishing all-steel watches from semi-steel watches: a. The all-steel case coating is bright and dark, and the edges and corners of the case are rounded, without a sharp feeling.
The copper case has a bright and whitish coating, sharp edges and corners on the back of the lugs, and the ring lines formed by the cutter can be clearly seen on the back of the lugs. And the texture is different in depth and size, and the arrangement is loose and uneven. The all-steel case, on the other hand, has a delicate and well-proportioned pattern, and is closely and neatly arranged.
b. Gently scrape the angular part of the lug (which can be inspected on the inside of the back of the lug) with a knife for a short distance, if the inside is yellow, it is a copper case. c. The corrosion resistance of the copper case is poor, and if it is not properly maintained, it is easy to fade (yellow or red), blistering or peeling of the coating after a period of use. Mechanical watch:
Timing instruments with mechanical vibrating systems, such as pendulum clocks, balance wheel clocks, etc. Mechanical watches work on the principle of using a vibration system with a constant cycle and continuous vibration; Multiply the vibration period at the time of vibration by the number of vibrations, which is equal to the time elapsed, time = vibration period The number of vibrations. Generally, it is composed of several parts, such as energy, gear train, escapement mechanism, vibration system, pointer mechanism and additional mechanism.
Power - clockwork or hammer, to provide the mechanical clock when working energy, through the gear train speed increase so that a bar can run continuously for many days, the escapement mechanism makes the clock clock timing frequency in line with people's "second" idea, the rudder or balance wheel controls the speed of the clock, and the time (engraver) mechanism tells people: what time is the last ring. Electronic Watch:
The basic part is made up of electronic components. The working principle of electronic clocks is based on the physical phenomenon of "electricity generates magnetism, and magnetism generates electricity". That is, it is converted from electrical energy to magnetic energy, and then from magnetic energy to mechanical energy, which drives the hour and minute hands to run and achieves the purpose of timekeeping.
Transistor balance clock: It uses a dry battery as an energy source, a transistor as a switch, and a balance spring as an oscillation system. Quartz watch:
Quartz watches use "quartz crystals" as oscillators, and control the motor operation through electronic frequency division, driving the pointer, and the accuracy of the time is very high.

There are many situations in life that can cause the glass of a watch to be damaged, such as scratches, cracks, broken corners, or complete breakage, depending on the extent of the damage. If it is only scratches and cracks, it can be improvised, and if the corners are broken and completely broken, the glass of the watch must be replaced. Severe damage to the glass will cause the watch to be unsealed, which will affect the waterproof function.
From the perspective of the material of the watch glass, the plastic glass of the old-fashioned watch will not burst, while the mineral watch glass, especially the popular sapphire watch glass, is more likely to burst.
Some watches only support life waterproof, and the waterproof performance is not high, if you take these watches that only support life waterproof to swim or the like, it is likely to be fogged into the water. In addition, the watch is produced in a dust-free environment, but the inside of the watch is not a vacuum, there is air. In other words, too large temperature difference may also cause the watch to fog up, and the rapid change of the temperature of the wearing environment, according to the principle of thermal expansion and cold contraction, will lead to fogging of the watch covering.
When the temperature is high, the water is gaseous, and when the outside temperature decreases, the temperature of the glass sheet on the surface of the hand is low, and the water vapor liquefies to form small water droplets.
In addition to artificially disassembling the back cover of the watch, there are two main reasons for the dust of the watch. First, you should first check whether your watch mask is tight, whether there are cracks due to aging or the whole is loose with the case (ring). Because the watch is not well sealed, it usually enters the water when it enters the dust.
The second reason is due to internal wear, as the ash on the dial does not come from the outside.
When taking care of a movement watch. The requirements for the sealing of the case are very high, if your watch is not waterproof, then dust, water vapor and other impurities are easy to the inside of the movement in the near future, when you find that there is fog on the glass, you must remove the water vapor in time, generally one or two years to maintain it! If it is a watch with strong waterproof performance, the maintenance is generally about 3 years.
Quartz movement watches also need to be maintained, and it is best to choose to replace the battery 3 to 4 times.
Reasons why a mechanical watch won't go Dead battery: The most common reason why a Tissot quartz watch won't go is when the battery is dead. Workaround:
Replace it with a new battery. Lack of power: Some friends do not wear the watch every day, or wear it for a short time every day, which leads to the lack of power of the automatic watch and the watch does not go.
Automatic watches wind the watch by moving the arm, and if you don't exercise enough or don't wear it, the watch won't go. This principle is the case with various brands of automatic watches. Workaround:
Wear more, exercise more, and remember to wind it when you don't wear it.

Guard. Watches are only used to keep time. Ten dollars for a watch. Hi, 10,000 dollars a watch. Maybe you feel different. But I can't stand the fact that he runs for the same amount of time.

(1) Wear.
When copying the watch, the sweat on the hands is corrosive to the case, and the all-steel case is made of nickel-chromium alloy
The corrosion resistance can be better, the semi-steel case is copper, long-term contact with sweat, easy to corrode, should be wiped off with a soft cloth or pad plastic watch holder frequently, to prevent it from being eroded by sweat.
2) Do not open the back cover of the watch at will, so as not to enter the movement and affect the normal operation of the watch.
3) Do not put the watch in a closet with mothballs to avoid the deterioration of the watch oil.
4) Do not put the watch on the radio or TV to avoid magnetization.
5) Watches that are not worn for a long time should be wound regularly once a month so that the parts will not be in a stationary state for a long time, so as to ensure the operation performance of the watch machine.
