Standard Time and Daylight Saving Time Setting

Except for China time zones, setting standard time/daylight saving time to AUTO will cause standard time/ daylight saving time to switch automatically in accordance with the time calibration signal. In locations not covered by a time calibration signal, you need to switch manually.

Note

Daylight saving time (DST), or summer time as it is known in some countries, calls for setting clocks ahead one hour from standard time during the summer season.

Note that the period during which and the areas where Daylight saving time is applied depend on each country. Some countries or geographic areas may not use summer time.

1.In the Timekeeping Mode, unlock the crown and then pull it out.

The c Second Hand will move to the currently selected Home City code.

The v Mode Hand will move to STD (standard time) or DST (daylight saving time).

2.Hold down C for at least five seconds until the watch beeps.

Each time you perform the above operation, the v Mode Hand will switch between MNL (manual switching) and AUTO (auto switching).

After about two seconds, the v Mode Hand will move back to STD or DST.
