as a high-precision timing instrument and artistic ornament, the correct use and maintenance of watches are very important, which can prolong the service life and precision of watches and the beauty of appearance parts, making them more convenient for your work and life.
31. About exterior parts maintenance
(1) watchcase and Watchband: the watchcase watchband of the watch is made of many kinds of materials, such as tungsten titanium alloy, high-tech ceramics, stainless steel, soft fiber, ordinary steel, etc, when wearing, try to avoid friction and pongee with special bodies that exceed or have the same hardness. It is also necessary to clean the watchcase strap regularly. In addition, seawater, salt water bath, perfume, shampoo, nail polish, nail polish remover and some cosmetics containing chemicals have certain corrosion to the gold-plated layer and metal surface of the watch, contact should be avoided.
(2) watch cover: Watch cover can basically be divided into synthetic epoxy glue, mineral glass and sapphire crystal glass. The wear resistance of synthetic epoxy glue is slightly poor, and scratches are easy to occur, but the impact resistance is relatively strong; The sapphire crystal glass is worn, but the material is relatively crisp and afraid of violent impact; The mineral glass is between the two. Even anti-wear sapphire crystal glass should not pay attention to impurities contained in diamonds, grindstones, sandpaper, nail file, chain link fencing stone surface, concrete wall surface, etc., so as not to scratch its surface.
2. About watch waterproof
30 m waterproof: refers to life waterproof, hand washing, face washing, rain, car splash, etc.
50 m waterproof: suitable for fishing, car washing, shower, swimming, etc.
More than 100 meters waterproof: suitable for diving, diving, etc.
Watch cover, watchcase and strap-watch maintenance common sense
the materials of watch cover are divided into organic glass, mineral crystal glass, sapphire crystal glass, etc.
The common materials of watchcase and watchband include plastic, copper, stainless steel, tungsten titanium alloy, high-tech ceramics, precious metals, etc.
Sapphire glass, tungsten titanium alloy and high-tech ceramics are all materials that are not easy to wear, and their hardness is Mohs Grade 9, Grade 8 and grade 7 respectively (diamond grade 10). Although these materials can resist abrasion, they cannot bear strong impact. At the same time, some materials with the same hardness or higher hardness, such as diamond, corundum, oxide metal and quartz crystal, may damage these materials; grindstone, sandpaper, nail file, granite surface, glass and ground all contain the above substances, which will scratch the surface of these materials.
Watch case and watchband need to be cleaned frequently, and can be washed and dried with warm water. Sweat, dirt and other materials will corrode the appearance of the watch, and can cause skin allergy of others. The newly bought watch should tear off the protective film on the back cover, otherwise sweat will remain in the middle to corrode the back cover.
Watch to avoid contact with all kinds of chemicals, once encountered, should be cleaned in time, so as not to cause coating discoloration, fall off or other losses.
If you are buying a belt watch, please note:
avoid contact with moisture and moisture to prevent discoloration and deformation.
Avoid exposure to sunlight for a long time to prevent fading.
Because the cortex is easy to penetrate, avoid contact with oily substances or cosmetics.
Maintenance of mechanical and quartz watches.
Precautions for using automatic mechanical watch:
1. Do not open the back cover for non-professionals to prevent damage.
2. After the watch is adjusted, be sure to push the handle back to the end.
3. Strap length adjustment: slightly adjust the movable safety pin position, and greatly adjust the strap with particles.
4. Mechanical automatic watch may be slow when the wearers are moving for hours, which is a normal phenomenon. Please rotate the handle head 20-30 times when using to make the clockwork initial winding.
Manual mechanical watch use precautions:
1. Spring up every 24 hours to ensure enough motivation to jump the day. Hold the watch upward at 12 o'clock when winding up, and rotate the watch clockwise to top full winding up. Be careful not to rotate the watch handle hard after the spring is full, so as not to break the arbor or spring.
2. To quickly adjust the calendar, you need to pull out the watch handle, set the time to 3 to 4 hours counterclockwise at exactly 12 o'clock, and then turn back to 12 o'clock clockwise. The calendar will be adjusted quickly for one day. Pull out the watch and rotate it so that the time-breaking needle can rotate two turns clockwise, or the calendar can jump smoothly for one day.
3. Adjust the length of the watchband slightly to move the position by safety pin, and the large adjustment needs to be disassembled and assembled by strap shaft.
4. Try not to touch water, steam, high temperature and corrosive gas when using, so as not to cause unnecessary damage to the movement and appearance. At the same time, avoid strong vibration and keep away from strong magnetic field environment.
5. Do not open the back cover by yourself.
Precautions for quartz watch use:
1. Do not open the back cover for non-professionals to prevent damage.
2. After the watch is adjusted, be sure to push the handle back to the end.
3. Strap length adjustment: slightly adjust the movable safety pin position, and greatly adjust the strap with particles. The above description is only for ordinary quartz watches and mechanical watches, excluding watches with special movements.
1. Battery
when the second hand of the quartz watch jumps or stops every few seconds and the battery power is exhausted, the battery should be replaced in time to avoid the movement damage caused by leaving the electroplating pool without electricity in the watch for a long time.
2. Temperature
quartz watch normal working environment temperature is-5 degrees to 50 degrees, do not put the watch in too high or too low temperature environment (such as sauna, hot spring), otherwise, it will affect the accuracy of the Watch and the service life of the battery. 3. Automatic mechanical watch
the automatic mechanical watch must be automatically put on the chain by the White movement of the arm of the wearer, so it must be worn for more than eight hours every day to ensure accurate timing. If you don't have enough time to wear during the day, it will lead to insufficient travel time. Therefore, it is suggested that when you take off the watch at night, swing the watch horizontally for one minute to supplement the winding.
4. Waterproof
waterproof watches have waterproof effect in daily life, but they cannot be worn for swimming or diving. It is recommended not to wear a bath to avoid short circuit or corrosion of the movement coil after water inflow affecting the Watch travel time.
5. Shock and vibration
watches made of high hardness materials (such as hard alloy, ceramics, Sapphire, etc.) have poor impact resistance. They should avoid falling and collision and friction with high hardness articles.
6. Magnetic watches should be kept away from objects with strong magnetic fields such as televisions, magnets, speakers, etc., so as to avoid damage to the movement caused by magnetic fields and affect the travel accuracy of watches.
7. Chemicals
watch should avoid contact with various solvents (such as alcohol and gasoline), Mercury, cosmetics, spray, adhesives, detergents, paints and other corrosive liquids or gases, so as to avoid case, the surface of the watchband changes color, deteriorates or damages due to erosion.
8. Care carefully
dust, moisture and moisture accumulated on watchcase and strap may cause corrosion. Therefore, the watch should be cleaned frequently with a soft dry cloth. Take care of your watch and use your watch correctly according to the instructions.
