Hold the watch in your left hand with the face facing you and the 12 o 'clock position facing up.
Rotate the crown with the right hand, the crown needs to be pulled out, and the pulling is divided into two stages (please pay attention to the strength).
First gear (slightly pulled out) : Thumbs up turn the crown (clockwise) - adjust the calendar
Thumbs down turn crown (counterclockwise) - adjust the week
Second gear (fully pulled out) : Rotate crown with thumb - adjust time
considerations
It is not appropriate to manually adjust the watch between 9 and 3 o 'clock on the watch.
Because this period of time is the running time of the calendar function, manual adjustment of the watch is easy to cause gear damage, so avoid this period of time, and then manually adjust the watch after the calendar jumps, otherwise it will cause loss to your love watch.
advice
First set the calendar to the previous day, pull out the crown to second gear (completely pulled out), turn the crown upward (clockwise), wait for the clock to turn 24 hours after the calendar will automatically jump to the correct date, and then continue to adjust the correct time today.
The first is the low battery voltage, in theory, the wave meter is often rechargeable solar energy battery, but it can not exclude the battery problem.
