1. When the watch is marked as 3bar, which means 30 meters waterproof, it represents that it is suitable for daily use and cannot be used for swimming or soaking in water. It can resist a small amount of hand washing, face washing, splashing water, and rainwater;

2. When the watch is marked with 5 bar, which means 50 meters waterproof, it represents that it is suitable for short distance swimming in shallow waters and cannot be used for diving or snorkeling;

3. When the watch is marked with 10 bar, it means 100 meters waterproof, and it represents suitable for swimming and snorkeling;

4. When the watch is marked with 20 bar, it means 200 meters waterproof, suitable for high impact sports in water and some diving activities, such as diving.

The so-called "Big Three" refers to the central layout position of the watch dial, which is equipped with an hour hand, minute hand, and second hand, and the three are located at the center point where they intersect coaxially.

The hour and minute hands share a dot, and a separate small disc is created for the small second hand to display its movement separately.

That is to say, adding a small window for the second hand on top of the original two pointer watch. Xiao San Zhen, also known as Short San Zhen or Two and a Half Needles.

Mainly from the wrist movement of the wearer, the watch's rotor swings during the owner's movement, thereby winding the watch. Therefore, when the wearer has little activity or does not wear it for a long time, the string force will be insufficient or empty, causing the watch to be inaccurate or stop moving.

Elderly people and those who frequently sit in offices and exercise less are not suitable to wear such watches. In this case, it is recommended that the wearer manually wind the watch regularly.

Adjust the calendar to the day before, for example, if today is the 30th, adjust the calendar to the 29th, then adjust the time clockwise and counterclockwise until the calendar automatically changes to the 30th, indicating that it is currently midnight on the 30th, and then adjust the time to the current time. This method avoids the situation where the watch changes the calendar at noon in the future. Note that if the current time is in the afternoon or evening, it will need to be adjusted again after 12 o'clock. Remember: Be careful not to adjust the calendar between 9pm and 3am. During this time, the gears for changing the calendar start to interlock. If you manually adjust the calendar, it is likely to cause gear damage or misalignment.

The back cover of waterproof watches will be labeled with 'WATER RESIST', while non waterproof watches will not have this label.

The reason why the quartz watch doesn't go away：

1. The quartz watch battery has no power or insufficient capacity, and needs to be replaced with a new battery. But pointer quartz electronic watches often find that the battery is dead in a short period of time, which is usually caused by high power consumption or low battery quality When encountering this situation, the first step is to identify the cause, troubleshoot, and then replace the battery with a new one.

2. Poor contact, mostly due to dirt on the positive and negative contact springs and poor contact with the battery. Poor contact may also occur between the signal output point on the circuit board and the lead out point of the coil wire. All of these can cause the circuit to become non-conductive, causing the quartz electronic watch to not run or not run properly. If the circuit is not connected due to poor contact, first thoroughly clean the contact surface and then reassemble it.

3. The stepper motor cannot rotate. The rotor of the stepper motor is a permanent magnet, which often gets stuck with the stator due to the adsorption of iron filings, causing the quartz meter pointer to stop moving or the time to stop.

Generally, quartz and electronic watches require batteries to provide power, and the battery life is usually around 1-2 years. When your watch experiences abnormal phenomena such as trembling hands, slow movement, or stopping, you should consider replacing the battery. Currently, the cost of button batteries is not high, but disassembling the watch is a technical task. It is not recommended to disassemble the watch and replace it yourself. It is best to go to a professional watch repair shop for replacement. Attention, the watch should be replaced or removed as soon as possible after the power is exhausted to avoid battery leakage and damage to the movement.

1. Low battery: If the quartz watch suddenly feels slow, it is likely caused by insufficient battery energy. You can take the watch to a designated repair center to check the battery level.

2. Watch magnetization: If the quartz watch movement is magnetized, the watch's time will also be inaccurate.

3. Impact: The internal components of quartz watches are arranged very tightly, and if they are hit or knocked, it is likely to cause the internal components to loosen or be damaged, which can also cause timekeeping problems.

If it is only a small amount of fog, it will disappear on its own after a long time. Alternatively, it can be baked under a light bulb, but not over a fire. Alternatively, the product can be packaged in a sealed bag and placed in a moisture-proof agent; Alternatively, the surface can be turned inward and the bottom shell can be turned outward, and worn upside down on the wrist. After two hours, the moisture can be eliminated. If there is a lot of water ingress and visible water droplets, it is necessary to seek professional repair services as soon as possible. Although waterproof watches for daily use have undergone certain waterproof treatments, they are generally not strictly inspected. It is recommended to avoid contact with water as much as possible when wearing them to prevent any unexpected situations.

The commonly referred to anti magnetism refers to the main components inside a watch being able to resist magnetism, while others cannot. So the magnetic field definitely has an impact on the watch. Especially for quartz watches, due to the fact that the micro thrusters inside the quartz watch that push the pointers are driven by magnetic energy, namely stepper motors, they are easily affected by magnetic field interference, which can cause pauses or display speed deviations. The quartz watch is inaccurate, mostly due to the influence of magnetic objects. The solution is simple, just stay away from the magnetic field and re chain.

1. Keep clean: The watch case and strap, such as close fitting clothing, will directly come into contact with human skin. If dirt is not cleaned, it is easy to dirty the cuffs of the clothes, and it can also cause skin itching and allergies. Therefore, it is necessary to keep the watch clean regularly. When you remove the watch, gently wipe the watch body, strap, and buckle with soft fabric to extend the life of the watch.

2. Pay attention to dust, water, and fog prevention, and avoid wearing them while taking a shower; Avoid prolonged exposure to sunlight that may affect the color and quality of the watch strap;

3. Keep away from magnetic objects: Do not bring the watch close to magnetic objects such as radios and televisions to avoid the watch being magnetized and affecting accuracy.

4. Do not open the back cover of the watch at will: to prevent dust from entering the movement and affecting the normal operation of the watch.

5. Regular winding of mechanical watches: Mechanical watches that are not worn for a long time should be wound once a month to prevent the parts from being in a static state for a long time and ensure the operational performance of the watch.

6. Other: When the mechanical watch is not in use, it is best to wind it up once a month to prevent the oil inside the watch from solidifying. Waterproof, shock resistant, and anti magnetic watches can only serve a preventive purpose. When using them, it is still necessary to avoid contact with water, magnetic fields, and strong vibrations to avoid damaging the movement and affecting its service life.

Wearing a watch has caused allergic reactions, with itching, red marks, and even red rashes on the skin. Please do not panic, as this is related to the person's physical condition and is often not a quality issue with the watch itself. At present, technology has found that using pure gold material for the watch case can significantly reduce skin allergies. There are three types of conditions and solutions for skin itching, rash formation, etc.:

1、Allergy to metal or leather: If it is confirmed that one is allergic to a certain metal or leather, then do not wear watches made of the corresponding material;

2、Allergies to rust, dirt, and sweat on the watch: If the watch has not been cleaned for a long time, gently wipe it with a damp towel;

3、Too tight and not breathable can cause allergies: loosen the strap to increase ventilation and air permeability. If the skin allergy persists for a long time, seek medical attention as soon as possible.

The hard gold process mainly consists of two key steps: vacuum melting of hard gold and physical pressurization。

1、Hard gold vacuum melting technology is different from traditional 3D hard gold technology. It involves adding trace elements to the gold raw material and then conducting high-temperature vacuum melting to increase the density between gold molecules and enhance their hardness; 

2、Physical pressurization uses a 300 ton heavy-duty hydraulic press to repeatedly punch the gold raw materials formed by vacuum melting dozens of times, further increasing density, improving product hardness, and enhancing wear resistance.

We will measure your wrist circumference and adjust the metal strap to the appropriate size when purchasing If you need to cut or lengthen it, you can adjust it by simply returning it to the factory; Cut off the watch strap and leave it to you for safekeeping So that it can be used when it needs to be extended in the future If there is no strap available anymore You need to purchase a watch strap extension at your own expense.

The difference in accuracy is due to the different movements used in these two watches. The national standard accuracy of quartz watches is ± 15 seconds per month, the national standard accuracy of high-quality mechanical watches is ± 30 seconds per day, and the accuracy of Sipnikin watches can basically reach ± 10 seconds per day. The accuracy of automatic winding mechanical watches is also affected by the way the watch is worn. Due to the continuous winding of the watch as your wrist swings, the strap must perfectly fit the wrist to avoid the loss of stored power. In addition, the performance of a watch is also affected by environmental factors such as temperature, pressure, humidity, and magnetic fields. The accuracy of mechanical watches is strongly affected by environmental factors such as temperature, inertia, frequent shocks, and magnetic fields. In addition, its accuracy is also affected by the winding state of the movement. To ensure optimal performance, it is necessary to chain the device by swinging the wrist. Therefore, the strap should be adjusted properly to fit the wrist and avoid power loss.

In terms of timekeeping, the second hand of a quartz watch jumps one step at a time, and the timekeeping is very accurate, generally requiring ± 15 seconds per month. The second hand of a mechanical watch moves continuously without interruption, and there may be errors in the timing. Generally, the daily deviation is ± 30 seconds, but the timing deviation of a Sipney watch can basically reach ± 10 seconds; 

In terms of watch usage, quartz watches are easy to use, and the battery can generally last for 2-4 years. After the battery fails, it can be replaced at a professional watch repair shop; Mechanical watches require manual winding of 20-25 turns when worn for the first time or stored for more than 36 hours due to insufficient power;

From the appearance, mechanical watches are thicker than quartz watches (depending on the brand), and some brands are also thinner, but generally they are manual mechanical watches. Watches that use mechanical movements mostly appear in a hollowed out form, with a semi transparent bottom cover that appears high-end, atmospheric, and textured. The finely crafted mechanical movement has a long service life and cultural collection value.
