1 to 3 years maintenance once.
1. Maintenance of common sense
(1) when wearing a watch, the hands of the sweat on the case is corrosive, full steel case due to nickel-chromium alloy, corrosion resistance is better, semi-steel case is copper, long term contact with perspiration, easy to corrode, should be often wiped with a soft cloth to wipe away the perspiration or padded with a plastic watch rest, in order to prevent it from being eroded by sweat;Room 903, 9/F, HNA Tianjin Center Office Tower, No. 219 Nanjing Road, Heping District, Tianjin (office entrance is located in the Guiyang Road and Xining Road). No. 903, 9th Floor, HNA Tianjin Center Office Building (the entrance to the office building is located at the intersection of Guiyang Road and Xining Road)
(2) Do not open the back cover of the watch, so as to avoid the dust into the movement affecting the normal work of the watch;
(3) Do not put the watch in the closet with mothballs, so as to avoid deterioration of the watch oil;
(4) Do not place the watch (4) Do not put the watch on the radio, television, so as not to magnetize;
(5) Long-term storage of the watch not to wear, should be regularly wound up once a month, so that the parts are not in a state of stasis for a long time, in order to ensure that the performance of the operation of the watch machine.
2. Watch cover renovation. After the watch is scratched out a lot of lines, you can first drop one or two drops of water on the watch, and then squeeze a little toothpaste coating, you can remove the scratches and make the watch as new.
3. Remove the water inside the watch. Accidentally case into the water, available in a granular material called silica gel and has been water together with the watch into a closed container, a few hours later, take out the watch, the water is all gone. This method is simple and economical, and does not cause any damage to the accuracy and life of the watch. Has been many times after the water absorption of silica gel, can be dried at 120 ℃ for a few hours, water absorption capacity can be regenerated, but also can be repeated many times.
4. It is not good to sleep with a luminous watch. Wear the watch on the wrist to sleep, if the watch is a luminous watch, it will bring adverse effects to the body.
5. Electronic watch knowledge
①Electronic watch at a temperature of 25 ~ 28 ℃, a day and night time error in one second or less, when the temperature to 0 ℃ or more than 50 ℃, every day and night will be slowed down two seconds. Meanwhile, when the temperature is up to 60℃, the LCD board will turn black, and when the temperature drops below 0℃, the LCD board will lose its display, so in winter, the electronic watch can only be worn on the wrist to keep its normal timekeeping with the constant temperature of the human body. In addition, high temperature and too low temperature will also cause battery leakage and corrosion of the movement.
②Electronic watch batteries are generally available for more than a year, but the lighting power consumption, open a second of power consumption is equivalent to more than one hour of timekeeping. When the battery is almost finished, the light will become dim, or the digital display will be dimmed or even disappear when it is turned on. When replacing the battery, if you do not know how to repair the watch, you should send it to a watch repair store for installation. And there is no standardization of battery specifications, there are many batteries of various grades, which can't be adopted at will.
The electronic watch should pay attention to: press the button can not be too hard, so as to avoid malfunctioning; LCD board use five to seven years need to be replaced by a new one; the battery should be taken out in a timely manner, so as to avoid the flow of liquid corrosion of the movement. Found that the lights do not light, button failure, timing suddenly have a large error to repair in a timely manner, may be poor contact with the components of the solder joints or off.
Electronic watch, especially digital electronic watch, waterproof performance is generally poor. Although some of them have the word "waterproof" printed on the manual or back cover, you should avoid contact with water as much as possible.
The structure of the electronic watch is different from the mechanical watch, are electronic circuits and electronic components, in case of water, it will be "catastrophic", so that the whole watch is scrapped. Especially the liquid crystal board and integrated line, not only afraid of water, is damp, a long time will also appear failure. Therefore, it is better to take off the watch when you wash your face or do laundry. When it rains, prevent splashing rainwater. If you find that the electronic watch into the water, or the inner wall of the watch mask son gathered moisture, should be immediately sent to the watch repair store for de-watering, moisture treatment.
Waterproofness of watches
The waterproofness of watches is based on the waterproof rubber rings on the watch mirror, back cover, and handle to reach the corresponding standards. All waterproof watches are marked with "WATER RESISTANT" or "WATER PROOF" on the back cover. Watches without waterproof markings are dustproof only and should be protected from water. 30 meters (3ATM, i.e., 3 atmospheres) waterproof watches can be used for daily grooming or in the rain, i.e., water droplets only splash on the surface without any water pressure being applied to the watch. 50 meters waterproof watches can be used for swimming and general household chores, while 100 meters waterproof watches can be used for underwater work, such as swimming and scuba diving.
The aging of the waterproof rubber ring will affect the waterproof performance of the watch, so the waterproof rubber ring and the head of the watch (which contains the waterproof ring) should be replaced regularly according to the usage. Quartz watches must replace the waterproof element at the same time each time the battery is changed to ensure good waterproof performance.
Any waterproof watch should not be worn in a hot bath, sauna, or in an environment where the temperature changes greatly. Because the waterproof rubber ring will be affected by temperature expansion and contraction of the gap and accelerate the aging caused by water and water condensation inside the table, serious damage to the mechanism.
Watches into the water how to do
If the water is not serious, just a layer of fog in the table glass, this time, we can use a few layers of toilet paper or moisture-absorbent flannel will be wrapped tightly, in the distance from the 40-watt light bulb 15 centimeters away from the baking for about 30 minutes, you can eliminate the water vapor. Do not bake the table mask * near the fire directly, so as not to make the table deformed by the heat. You can also put the watch mask towards the inside and the bottom case towards the outside, and wear it on the wrist, and the water can be eliminated after two hours. If the water is serious, it is best to immediately send the watch store to wipe the oil, remove the moisture of the movement, in order to avoid rusting parts.
How to care for mechanical watches
1. It is best to wind the watch at a fixed time every day, once on the full. Wind up the watch handle to turn fast and slow to be appropriate, do not get too tight. If it is too tight, the clockwork will be easily stuck by the oil in the clockwork box. When the clockwork is relaxed, it is easy to be broken because of the excessive elasticity.
2. The watch is most avoiding violent vibration, playing ball or striking something with your hand, it is best to take it down. Watches are also afraid of water immersion. Therefore, when washing clothes, washing hands or doing other work in contact with water, it is best to take down the watch. If there is fog or water spots on the watch glass, you should overhaul it in time, wipe off the fog and water spots, and dry the center of the watch. However, if there is only some fog, it will disappear by itself when the climate is dry.
3. Don't open the table cover at will, lest the dust fall in; more not to dial, bad should be sent to the watch store in time for repair.
4. When the watch is not worn, do not put the watch on the radio, so as not to be magnetized by the magnet of the speaker, affecting the time. The watch should not be put together with camphor, because camphor is a kind of extremely volatile substance, which can easily make the oil solidify and lose the lubrication effect, so as to damage the accuracy of the watch.
5. The hardness of the watch glass is not high, so it should avoid rubbing with hard and sharp substances, avoiding high pressure, high heat and corrosion of chemical reagents, so as to avoid rubbing hair or damage. If there are slight traces of scratching, can be coated with toothpaste on the flannel, in the table glass above the back and forth rubbing, you can eliminate scratches. Remember not to rub with alcohol, in order to prevent the table glass and alcohol chemical reaction and cracking.
