instructions

1. Non professionals are advised not to open the back cover of the watch to prevent damage
2. The winding and calibration time of mechanical watches In order to ensure the continuous operation of automatic winding watches (automatic mechanical watches), We suggest that you wear this watch every day. If you cannot wear it every day, please wind the watch (rotate the crown clockwise 20 times) before each wear Please do not adjust the date on the watch between 9pm and 3am to avoid damaging the mechanical system of the watch, as the gear system of the movement is in operation during this time period and the automatic date change has been completed
3. Preservation of Long term Idle Watches
If you do not wear a watch for a long time, please store the watch properly in a watch box to avoid the watch being broken or bumped, which will greatly reduce the probability of damage to the watch. If you want to wear a mechanical watch that has been idle for a long time, you must first re wind it; When the mainspring of a mechanical watch is at its most relaxed, there may be a phenomenon of the hour and minute hands slowing down or speeding up, so it should be wound first and then aligned with the time The battery life of quartz watches is usually over two years. If you plan to leave the watch unused for weeks or months, it is recommended to pull out the crown before storing it. This will interrupt the power supply to the watch movement to extend the battery life. Once the battery is depleted, it must be replaced immediately at after-sales service
4. Waterproof performance
The waterproof of the watch relies on the waterproof rubber ring at the mirror, back cover, and handle to meet the corresponding standards. All waterproof watches are marked with the English words "WATER RESISTANT" or "WATER PROOF" on the bottom cover. Watches without waterproof markings can only prevent dust and should be avoided from getting wet. A 30 meter (3ATM, 3 atmospheres) waterproof watch can be used for daily grooming or in the rain, where water droplets only splash on the surface without any water pressure applied to the watch. A 50 meter waterproof watch can be used for swimming and general household chores, a 100 meter waterproof watch can be used for swimming, and a 200 meter or more waterproof watch can be used for swimming The table can be used for underwater work such as diving The aging of the waterproof rubber ring can affect the waterproof performance of the watch, so the waterproof rubber ring and head (including the waterproof ring) of the watch Regular replacement is required according to usage. The waterproof components of quartz watches must be replaced at the same time as each battery change to ensure good waterproof performance. Any waterproof watch should not be worn in a hot water bath, sauna, or in an environment with large temperature changes. Because the waterproof rubber ring is affected by temperature, it will expand and shrink due to heat, resulting in gaps and accelerated aging, causing water ingress and water condensation inside the watch, which can seriously damage the components
5. Shock and vibration Generally, wearing and regular sports activities will not cause damage to the watch from shock But when wearing, please be sure to avoid the watch falling to the ground or colliding with hard objects to avoid damage to the watch. Please avoid wearing the watch and jewelry on the same wrist at the same time to avoid scratching each other
6. Magnetic field Strong magnetism, although it will not cause substantial damage to the watch itself, But it will affect the accuracy of the watch. Therefore, do not expose the watch to strong magnetic fields. When the watch is magnetized, it usually makes the watch run faster. After this situation occurs, go to the after-sales service to demagnetize it. The operation is very simple and can be done in a few seconds
7. Case and strap The dust, moisture, and dampness accumulated on the watch case and metal strap may cause rust. To prevent corrosion caused by sweat, it is recommended to regularly use a dry and soft cloth to clean the surface of the watch and strap. After the watch is soaked in seawater, it must be rinsed with warm water and thoroughly dried. In seasons where sweating is common, the strap can be loosened to improve breathability, with an ideal looseness of about one finger Genuine leather watch straps may experience normal wear and tear due to wear and use, typically with a lifespan of 2-3 years. Do not immerse the strap in water or other liquids. Prolonged exposure to sunlight or artificial lighting may alter the color of the strap,
8. Spiral tightening crown
When the spiral crown watch is on the school team, it must be loosened counterclockwise before use. After the crown pops out, it can be adjusted. After completion, it must be pushed back and locked
9. Date adjustment steps
Step 1: Pull out the crown to the second gear position and adjust the hour hand of the watch to 6 o'clock
