Requesting instructions for use and maintenance of mechanical watches

Hello friends, I found this article for you. Mechanical watch maintenance instructions 1. Mechanical watch error The allowable error range of a mechanical watch is ±30 seconds/day. The average error range of the movement certified by the Observatory is between -4 seconds/day and +6 seconds/day. The specific error is based on It depends on the movement used in the watch. It is not based on the principle that the higher the price, the smaller the error. The power source of an automatic mechanical watch is that the swing of the wearer's wrist generates energy to wind the spring. A fully wound automatic mechanical watch can run continuously. About 36 hours: If it is guaranteed to be worn normally every day, it can operate for about 15 hours. If it is not worn for more than the above time or the swing is insufficient (the wearer does not exercise much), it will cause the watch to stop. You should first wear it before wearing it again. Wind up the watch enough. 2. Why does an automatic watch stop? First of all, let’s introduce what a fully automatic mechanical watch is. It relies on the automatic winding mechanism to wind up the mainspring when the automatic rotor rotates in any direction (visible on the transparent bottom cover of the watch). It is conceivable that as long as the watch is worn on the hand, as the arm moves, the automatic rotor will also rotate to generate energy. Generally, a fully automatic watch should be worn on the hand for more than 8 hours a day to replenish the winding energy, but this is not absolute. It is recommended that you wear a watch during holidays. Only when you wear it on your hand to continuously replenish energy to the spring, the watch will not stop running. Nowadays, it is common for people working in offices that their watches often stop. In addition to the movement, it is also because the wearer does not exercise enough and cannot replenish enough energy to the spring. If this is the case, you can use a hand dial to wind it. Clockwork method to compensate. 3. Do you usually need to wind the automatic watch? An automatic watch is a general hand-wound watch with an automatic component added. The automatic component includes an automatic tourbillon and an automatic wheel. The automatic watches we sell are out of the box. The time is usually at a standstill. First, the salesperson needs to help the customer wind up the clockwork. Then, as long as the customer wears it for enough time every day, the automatic rotor can replenish energy to the clockwork, so that the automatic watch can run normally. We should advocate that automatic watches should be used as much as possible. Use less hand-dial winding, because hand-dial winding requires a handle to drive many automatic wheels to rotate together. Automatic parts are very easy to wear, causing unnecessary maintenance costs for customers. 4. Among luxury watches, why do hand-wound watches have larger errors than ordinary automatic watches? The high-end automatic watches on the market (such as Rolex, Omega, etc.) have all been certified by the Observatory, and the average error range of the movement when leaving the factory is required to be - Between 4 seconds/day and +6 seconds/day. On the contrary, the requirements of various watch manufacturers for hand-wound watches focus on the materials used, which are generally precious metals; and the thickness of the watch, which is designed to be very thin. Manufacturers believe that the consumer group of luxury watches is a specific group of people. These people often own several watches and wear different styles of watches according to the occasion. Famous watches made of precious metals like this are usually considered banquet watches. Wearing this kind of watch is mainly a symbol of status. The accuracy of the watch itself is not paid much attention to. Therefore, most of them are two-hand watches, or even have no Waterproof properties. 5. Introduction to anti-shock and anti-magnetic properties (1) Watches generally have a certain anti-shock function, and the anti-shock function inside the watch can function even when hit by external forces. If the quartz watch battery is disconnected from the positive and negative poles, and the mechanical watch balance disc is misaligned, causing the watch to stop, giving you the illusion that the watch is broken, in fact, you only need to go to an authorized repair station to reinstall it in place. (2) The so-called antimagnetic watch does not mean that all parts in the watch are antimagnetic. Only the main parts, such as balance wheel, hairspring, spring, etc., are made of antimagnetic materials. (3) Although some watches have anti-shock and anti-magnetic functions, they can only play a preventive role, so you should avoid violent collisions or place the watch next to electrical appliances or magnetic objects that generate magnetic fields, such as TVs, stereos, and freezers. , mobile phones, induction cookers, electric mahjong tables, magnetic bags, etc. The above reasons may cause the watch to stop or become inaccurate. 6. How to solve the phenomenon of magnetization in mechanical watches. Once the watch becomes magnetized, it will suddenly run very fast, even faster than 1-2 hours/day. When wearing a mechanical watch, be careful to stay away from magnetic fields, such as near stereos, televisions, mobile phones and other electrical appliances. Magnetization is a common phenomenon nowadays, and the solution is not difficult. You only need to go to an authorized maintenance department to use special equipment to demagnetize the watch. It only takes 30 seconds for the watch to be demagnetized without affecting the performance of the watch.

7. Introduction to waterproof performance (1) The waterproof performance of the watch mainly relies on the waterproof rubber rings on the watch mirror, back cover, crown, etc., and uses a screw-type crown to meet the corresponding waterproof standards. (2) The waterproof performance of watches is usually classified according to its level:

- Not waterproof (no logo on the back cover of the watch)

- Sweat-proof (SWEAT-RESISTANT)

- General waterproof (WATER-RESISTANT), 30 meters waterproof (30M, 3ATM, 3BAR), 50 meters waterproof (50M, 5ATM, 5BAR).

- The diving watch is 100 meters waterproof, 200 meters waterproof, 300 meters waterproof, etc. (3) Regarding the waterproof performance of watches, national standards and international standards have clear regulations: All watches marked as waterproof must withstand at least 2 atmospheres of pressure, that is, no water can enter the depth of 20 meters. Water resistance of 30 meters means that the watch can withstand Subject to 3 atmospheres of pressure, and so on. The premise of this standard is that the test is conducted under laboratory conditions, the temperature is maintained at 20-25 degrees Celsius, and the watch and water are stationary. In this case, if the watch is waterproof, it is qualified. 8. Waterproof precautions: (1) A 30-meter waterproof watch means that it can withstand 3 kilograms of pressure per square centimeter area, which is equivalent to a pressure of 30 meters in water depth in a static state, which is equivalent to a pressure of 3 atmospheres. This kind of watch is The design is mainly to prevent the movement from being damaged by dust and moisture, and is not suitable for immersion in water or swimming. (2) Waterproof watches of 100 meters or above are suitable for water sports such as snorkeling. (3) All waterproof watches cannot be used in hot water baths, saunas or environments with drastic temperature changes, because the waterproof rubber ring will expand and contract due to temperature, causing gaps and accelerating aging, which will affect the waterproof function. Water damage to the watch caused by the above improper use factors will not be covered by the warranty. (4) The crown should be kept in the normal position and the screw crown should be tightened. Do not adjust the crown in water. (5) The waterproof rubber ring and crown of the watch must be replaced regularly according to usage. 9. Some watches are marked as waterproof, but how can water vapor enter? Under normal circumstances, a waterproof watch does not mean that water vapor will not enter. If you take a watch while taking a bath, the waterproof rubber ring used for the watch will be corroded by chemicals such as detergents and will accelerate aging, and the waterproof function will be ineffective. During the rainy season, the temperature in the air is relatively high, and there are large temperature changes, such as saunas, air-conditioned rooms, etc., which will cause water vapor to enter the watch. The rubber ring gradually ages over time and its waterproof performance gradually decreases. Once water vapor is found in the watch, you should go to an authorized repair station for treatment in time to avoid causing parts to rust and shortening the service life of the watch. 10. Will the watch be waterproof if the back cover is opened? We know that the waterproof function of the watch mainly relies on the rubber waterproof apron to be fixed on the watch mirror. The joint between the back cover and crown and the watch case forms a waterproof seal. However, if you often wear a watch and take hot baths or saunas, it will accelerate the aging and deformation of the waterproof rubber ring. In addition to high temperatures, the acidic substances in sweat, chlorine and perfume in the swimming pool will affect the hardening of the waterproof rubber ring, reducing its waterproof performance. Based on experience, it is recommended that you send your watch to an authorized repair station every 1-2 years to test its waterproof performance. 11. Watch mirror, watch case and watch strap (1) The materials of watch mirror are divided into organic glass, mineral crystal glass, sapphire crystal glass, etc. Common materials for watch cases and straps include plastic, copper, stainless steel, tungsten-titanium alloy, high-tech ceramics, precious metals, etc. (2) Sapphire glass, tungsten-titanium alloy and high-tech ceramics are all materials that are not easy to wear. Their hardness is Mohs level 9, level 8, and level 7 respectively (diamond is level 10). Although these materials can resist wear and tear, they cannot withstand strong impacts. At the same time, some substances with the same or higher hardness, such as diamonds, corundum, oxidized metals, and quartz crystals, may damage these materials; grinding stones, sandpaper, and nails Foil, granite surfaces, mixed soil walls, glass and floors all contain the above substances, which will scratch the surfaces of these materials. (3) The watch case and strap need to be cleaned frequently and can be washed and dried with warm water. Sweat, dirt, etc. will corrode the appearance materials of the watch and may cause skin allergies in some people. When buying a new watch, you need to peel off the protective film on the back cover, otherwise sweat will remain in the middle and corrode the back cover. Watches should avoid contact with various chemicals. Once they come into contact with them, they should be cleaned in time to avoid discoloration, peeling off or other losses of the coating.

12. If you purchase a leather watch, please note: 1. Avoid contact with water and moisture to prevent discoloration and deformation.

2. Avoid long-term exposure to sunlight to prevent fading.

3. Since the cortex is easy to penetrate, avoid contact with greasy substances or cosmetics.

13. Recommendations for the use of mechanical watches (1) Watches with manual winding movements should be wound at the same time every day as much as possible so that the watch has enough energy to operate in the next 24 hours. (2) The energy of a watch with an automatic winding movement comes from the movement of the wearer's arm, so manual winding is not required under normal wearing conditions. Manual winding can only be used when the wearer does not exercise enough to replenish sufficient energy for the spring. To compensate, the crown rotation should be controlled within twenty turns when winding. (3) If a self-winding watch has not been worn for more than 40 hours, you should turn the crown twenty turns to restart the movement's drive system when you wear it again. (4) To prevent moisture from penetrating into the case and maintain the waterproof performance of the watch, please ensure that the crown is locked at all times.

14. Maintenance and repair suggestions In order to ensure the normal operation and accuracy of your watch, we recommend that your watch should be maintained regularly (1) Waterproof the watch once a year Testing and exterior cleaning.

(2) For watches with mechanical movements, complete machine maintenance should be performed every 3-5 years.

(3) This not only keeps the watch in good operating condition, but also effectively extends its service life. However, the above maintenance services are only applicable to watches under normal wearing conditions, and do not include watches that are worn abnormally or are subject to constant impact. 15. Warranty conditions (1) Please properly keep the watch purchase voucher, warranty card and other documents, and do not open the watch case and battery back cover by yourself in order to obtain effective and perfect after-sales service. If the maintenance voucher is erased or deleted, our company reserves the right to reject it. The right to provide warranty services. (2) According to the product use and maintenance instructions in the package, the warranty period does not include any normal wear and tear of the belt or watch appearance. (3) If the watch is exposed to an environment with extremely high or low temperatures, or the crown is not locked, it is easy for moisture to penetrate into the watch or even liquid. Improper operation is not covered by the product warranty. (4) Product failure caused by opening or modifying the product at an unauthorized maintenance point is not covered by this warranty. (5) For repairs or replacements performed by an authorized product maintenance unit, the parts repaired and replaced shall belong to the authorized unit. 16. Precautions (1) Do not adjust the calendar, day of the week, and moon phase of the watch between 21:00 PM and 3:00 AM. During this period, the calendar function is in operation and the gear meshing is low. Frequent movements can damage the internal parts of the watch. (2) The weekly calendar tab is divided into two types: fast and slow due to different formats. The first type of calendar tab is completed within ±5 minutes, and the second type is completed within ±5 minutes. The calendar tab is completed within 3 hours. (3) If you encounter a watch with a screw-type crown, do not pull it out by force. Please first turn the crown counterclockwise to open the lock. After adjusting the time, turn the crown clockwise and push it into the lock. To avoid water intrusion. (4) If you need to adjust the date of a watch with a calendar, please first adjust the calendar to the day before the date you need, and then turn the hour hand to adjust the date. The date will change when the hour hand passes 12 o'clock midnight, so you can avoid direct adjustment. Dates cause confusion between day and night. (5) If you have a watch with complex functions, please read the accompanying manual carefully.
