Watch date adjustment method:
First, pull out the crown, let all the pointers stop, adjust the time. Push back the crown and adjust the date and week. Adjustment date and the day from week to the day before your scheduled date.
Matters needing attention:
Press the button too hard to avoid failure; the LCD board needs to be replaced for five to seven years; the battery should be removed in time without electricity, so as not to corrode the machine core. When it is found that the lamp is not on, the button is out of order, and there is a sudden big error in timing, it should be repaired in time. It may be that the solder joints of the components are not in good contact or have been removed.
Although some of them have the words "waterproof" printed on the instructions or back cover, they should try to avoid contact with water. Electronic watches are different from mechanical watches in structure. They are all electronic circuits and components. If water enters, it will be "catastrophic" and scrap the whole watch.
Therefore, it is better to take off the watch when washing your face and laundry. When it rains, keep the rain from splashing. If it is found that the electronic watch is in water or that there is water vapor on the inner wall of the watch cover, it should be sent to the watch repair shop immediately for dewatering and dehumidification treatment.
1. If a watch with spiral crown is used, do not pull it out hard. Please turn the locked crown counter-clockwise first. After adjusting the time, turn the crown clockwise and push it into the lock, so as not to enter the water!
2. Next, pay attention to the forbidden area of the machine core of the mechanical watch from 21:00 p.m. to 4:00 a.m. during this period, it is not appropriate to adjust on weekdays and calendars, otherwise the machine core will be damaged.
3. Do not adjust the time counter-clockwise between 21:00 and 3:00, because in this period of week, the calendar gear in the switching, long time reverse direction adjustment will damage the internal parts, other periods of clockwise, counter-clockwise can be adjusted freely.
