Before using this guide, we recommend:

• Download official EQW-T620 Manual →

All settings are clearly explained and understandable.

1. In the Timekeeping Mode, keep A depressed (for about five seconds) as the Second Hand goes through the following sequence.

• Moves to YES (or Y for some models) or NO (N) to indicate the last signal reception result, then to READY (R), and then to the city code of the currently selected Home City.
• At this time, the Right Dial Hand will indicate the Home City’s current daylight saving time setting (STD or DST).

2. Change the Home City and daylight saving time (DST) settings, if you want.

• For details about these settings, see steps 2 and 3 under “To confi gure Home City settings”.
• In the following steps, each press of C cycles between settings as shown below.

3. Press C.

• The watch will beep, and the Second Hand and Right Dial Hand will move to their 12 o’clock positions. This is the time setting mode.

4. Use D (+) and B (–) to change the time (hour and minute) setting.

• Each press of either button will move the hands ( Hour Hand and Minute Hand) one minute.
• Holding down D or B will start high-speed z Hour Hand and c Minute Hand movement in the applicable direction. To stop high-speed hand movement, press any button.
• The b Lower Dial Hand and Hour Hand move in sync with each other.
• When setting the time, make sure that the b Lower Dial Hand indicates the proper a.m./p.m. hour.
• If you want to change the date setting at this time, press C and perform the procedure starting from step 3 under “To change the current date setting manually”.

5. After the time setting is the way you want, press A to return to the Timekeeping Mode.

• This will cause the Second Hand to move automatically to 12 o’clock and resume movement from there.
