Supplementary instructions for waterproof watches, how is the waterproof of the watch done?

The most important thing for a watch to be waterproof is the sealing ring, or O-ream, or I-ream, which is made of rubber, nylon or Teflon, which forms a waterproof seal on the glass, the rim, the case back and the joint between the jaw and the case. The degree of sealing is the waterproof level, and the common marks are: 30m, 50m, 100m, 200m, etc.

In addition, the thickness and material of the case determine whether a watch is safe to wear underwater. As a rule, watches labelled with water resistance must reach two atmospheres (2 bar). The detection method is:

Hold pressure at 2 bar for 60 seconds and the air flow should not exceed 50 micrograms.

Why isn't it labeled "completely waterproof"? According to the Code issued by the Federal Trade Commission of the United States, a seller of a watch may not mark his watch as "fully water-resistant". Even if the watch is designed for deep-sea diving, it cannot be claimed to be completely water-resistant.

In other words, there is no such thing as a watch that is absolutely water-resistant.

Precautions during the use of water-resistant watches:

Wearing a waterproof watch for swimming chooses a 100m waterproof watch, which is safer. Although the ordinary 30m waterproof meter can withstand 3 atmospheres, its detection premise is under laboratory conditions, that is, the temperature is 20-25°, and the water and the meter are stationary. When swimming, the watch and the water are relatively moving, with a certain impact, and the pressure between the water and the watch is often much greater than 3 atmospheres.

As a result, the watch is susceptible to water ingress.

The waterproof meter does not allow hot baths and saunas. In addition, according to the principle of thermal expansion and cold contraction, each component of the watch is different due to different materials, shapes and sizes, and when the temperature changes greatly, the amount of expansion and contraction deformation is different, and it is easy to produce tiny gaps, causing water to enter the watch. Occasionally, there is no water ingress in the watch, which means that the watch is waterproof, but in the long run, it will accelerate the aging of the waterproof parts of the watch and affect the normal service life of the watch.

The watch that has been flooded is still waterproof when it is tested on the waterproof machine, which is caused by improper use, and the cold and heat (such as exposure to the sun or the air-conditioned room with low temperature) cause the waterproof parts of the watch to be instantly deformed, and the water vapor enters, and the environment is normal, and the waterproof parts return to normal, and still have the waterproof function.

At present, any waterproof watch, whether it is marked as anti-xx meters, cannot be used in hot water (>40C°). There are two reasons: 1. The permeability of water molecules is greatly enhanced when the temperature rises, and all waterproof watches are designed based on cold water.

2. According to the thermal expansion and contraction, some components of the watch will expand to varying degrees under hot water conditions, resulting in the increase of possible gaps.

1. Prepare a box of waterproof oil. As shown in the figure below;

2. First of all, prepare a small screw cavity knife as the number of workers to open the watch cover.

3. Then use a small screwdriver to gently open the back cover of the watch.

4. Then use a bamboo skewer dipped in waterproof paste to evenly apply it to the rubber ring of the watch. (A thin layer can be high).

5. Finally, after applying the waterproof paste, put the back cover of the watch back and press it tightly.

Disassemble the back cover to see that there is a rubber waterproof ring on the back cover, apply the waterproof paste to the waterproof ring, and the periphery. However, you should not apply too much, as if you apply too much, the waterproof paste will be squeezed when the back cover is closed, and it will flow to the movement, and if a large amount of water paste gets on the movement, the movement may be damaged.

The use of waterproof paste is actually so simple, just apply it to the waterproof ring, and you don't need more, just apply a thin layer of Jiang. However, it should be noted that the waterproof performance largely depends on the rubber waterproof ring, not the waterproof paste, if the rubber waterproof ring on the back cover is aged, it must be replaced, and then waterproof on the waterproof circle.

1. The watch itself has a waterproof effect.

2. There are three positions of the watch with a waterproof ring, the bottom cover and the handle have a common point, and there is a small slot in the position of the waterproof ring, you will put the waterproof ring on the slot, but the normal installation of the bottom cover and the waterproof ring will be smeared with waterproof ointment, generally speaking, the waterproof ring of the watch glass should be stuck in the glass or set in.

The back cover is sealed and the cover is located.

The watch has a waterproof ring in three positions, the bottom cover and the handle have common points, the position of the waterproof ring has a small slot, put the waterproof ring on the silver Hanxiang groove, the bottom cover and the waterproof ring will be smeared with waterproof ointment, and the waterproof ring of the watch glass should pay attention to the waterproof ring stuck in the glass or set in.

How to maintain your watch:

1. When wearing a watch, the sweat on the hands is corrosive to the case, the all-steel case is nickel-chromium alloy, the corrosion resistance is better, the semi-steel case is copper, long-term contact with sweat, easy to corrode, should often be wiped off with a soft cloth or pad on the plastic watch bracket, 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 the wardrobe 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 static state for a long time, so as to ensure the operation performance of the watch machine.

30-50mm is not waterproof. It can resist the water that is accidentally spilled on daily hand washing and face washing.

100m-300m belongs to ordinary waterproofing. In most cases, it can prevent normal swimming.

Above 300mm is a diver's watch. Snorkeling only.

Models over 300 mm and equipped with an exhaust valve can be used for diving.

Even higher is the model that can cope with deeper dives.

But even a deep-diving model with a nominal 10,000 is a model that can be tied to a nuclear submarine and dive to the limit.

It cannot be used for hot baths and saunas.

And every time you wash the oil or open the cap. Always remember to apply water-repellent oil.

Regularly check the maintenance of waterproof aspects such as waterproof rings.

After a long time, the waterproof ring has been aged, and the waterproof oil has been almost consumed. The waterproofing effect will naturally decrease.

It refers to the general life waterproof, that is, the water droplets splashed when washing hands, and the raindrops that fall when it rains lightly. But pay attention not to take too long, to dry in time. It's no problem to wash your face, take a bath, and swim every day

The high fit between the watch body and the glass separates the inside and outside, creating a waterproof effect.

There are three main parts to do the waterproofing of the watch.

1) Sealing of the case and the watch (glass). The dielectric is not affected by changes in heat and cold, and is precisely integrated into the case, which is compressed and embedded in the case by a special rigging. A transparent adhesive is applied between the watch and the case.

2) The winding handle is sealed with the case but does not affect the use of the winding. The case has a tube that matches the inner seal of the handle, and silicone oil is added to meet the needs of water resistance and lubrication.

3.The caseback has a waterproof ring, which is sealed with sealant or silicone, and the caseback is screwed seamlessly to the case with a special key.

1. Prepare a box of waterproof oil. As shown in the figure below;

2. First of all, prepare a small screwdriver as a tool to open the watch cover.

3. Then use a small screwdriver to gently open the back cover of the watch.

4. Then use a bamboo skewer dipped in waterproof paste to evenly apply it to the rubber ring of the watch. (A thin layer is sufficient) 5. Finally, after applying the waterproof paste, cover the back cover of the watch and press it tightly.

There are three key points of watch waterproofing: the case back, the handle of the watch, and the meson of the watch need to use waterproof paste.

It is used for the back cover, seal ring out and at the table cover.

The back cover is sealed and the cover is located.

2. Then continue to remove the cover on the back of the watch, dip an appropriate amount of waterproof paste with a wooden stick or other finer tools, and apply it thinly and evenly on the rubber ring.

3. After evenly coating the waterproof paste, cover the watch cover that was removed before, and then tighten the removed parts and screws with a screwdriver, and you can wear them normally.

Generally, the waterproof specifications of watches are divided into the following types: 30 meters, 50 meters, 100 meters, 300 meters, and 500 meters.

Rice: refers to the general life waterproof, that is, the water droplets splashed when washing hands, and the raindrops that fall when it rains lightly, but pay attention to not being too long and not wearing them in the sauna.

Meters: There is no difference between 30 meters and can be ignored.

M: You can take a car wash and shower, but you can't soak in water.

m: Can be used for swimming, but only for shallow swimming. (Don't take it as if it's at 300 meters.) )

M: Only this level can dive underwater, if I remember correctly, that is, left and right, there may be more, but don't do it according to the established value, maybe that is the limit of the cavity that the watch can bear, so it is recommended not to use this method to test the performance of the watch.
