BREIL CHRONO ALARM DUAL TIME AS10 Mode D'emploi page 22

Note: The hour hand is not advanced rapidly even if the crown is continuously
clicked two or more times. Perform correction accurately 1 hour at a time.
Furthermore, the range of time difference correction is ± 23 hours based on
the current time.
4. Always make sure to return the crown to the normal position after correcting the time
difference.
Note: If the hour hand passes 12:00 AM (midnight) during correction, the date is
advanced by 1 day following completion of hand movement. If the time
difference is corrected in the counter-clockwise direction and the hour hand
passes back over 12:00 AM, although the date is corrected following
completion of hand movement , since the date is corrected by 30 days in the
clockwise direction, it takes about 2-3 minutes for the date to be corrected.
Pay attention to AM and PM when correcting time difference.
Note: When returning the time difference to the original setting, return the hour hand
in the direction opposite that when the time difference was corrected.
