The Precautions for Adjusting the Time, Calendar, Week of Watch
When setting the time, make sure to use the correct method specified for your particular watch model. Some watches have crowns that need to be pulled out to different positions for time adjustment. Avoid setting the time when the watch is in a state of high mechanical stress, such as during a sports activity or when it has been subjected to a shock.
For watches with calendars, be cautious when adjusting the date. Do not adjust the calendar between 9 pm and 3 am, as this is typically when the internal mechanisms are in the process of changing the date. Forcing the calendar adjustment during this time can damage the movement.
When setting the week display, ensure that it is synchronized correctly with the actual day of the week. Some watches may require manual adjustment of the week after a battery change or when there is a power interruption.
It's also important to handle the watch gently during the adjustment process. Avoid using excessive force on the crown or buttons, as this can lead to mechanical damage.
By following these precautions when adjusting the time, calendar, and week on your watch, you can ensure its proper functioning and longevity.
