"Notes": 1.This watch is a mechanical watch with a built-in rotor that rotates with the normal action of the wrist.When using it for the first time, the mainspring must be wound up tightly in order to transmit stable driving force to the mechanical parts.In the process of wearing the watch, you will need to ensure that there is enough power to drive the watch. In order to guarantee this, a certain amount of arm work is required.If the arm does not work as well, there will not be enough power to drive the watch, and time errors are likely to occur.In order to prevent errors such as stops and delays and to transmit stable driving force to the mechanical parts, use the watch for at least 8 hours a day. If there is any error, please wind up the mainspring. How to wind the mainspring: Turn the mainspring approximately 15 degrees clockwise without pulling it out of the crown. 2. When approaching magnetic products with strong magnetism such as televisions, computers, microwave ovens, etc., it may run faster.If you do not use it normally, it is better to leave it far away from magnetic products. 3. Regarding waterproofing: It is waterproof to the extent that it can withstand sweat in daily life, water droplets when washing your face, rain showers, etc. It cannot be worn in hot water or in the bathroom.The rubber gasket of the watch is easily heated and deteriorates.The water vapor molecules in that place are relatively small and can easily enter the inside of the case, so there is a high possibility of damaging the internal mechanical parts. 4. Adjustment for both hands: Pull out the crown and turn it counterclockwise. The time will be rewound to 12:00 on the small dial on the left. And continue rewinding. You will notice that the pointer for both local times is stuck and you can adjust the pointer according to the time difference. Time, then flip the clock counterclockwise back to 10:00. If the time is correct, proceed clockwise. You can see that the time is synchronized between the two locations.
