Time Adjustment

Your watch can connect with a phone to obtain information that it uses to adjust its date and time setting.

Important! Disable auto time adjustment whenever you are in a hospital, inside an aircraft, or in any other area where use of a phone is prohibited or restricted.

Using the Watch in a Medical Facility or Aircraft

Referring to the information below, configure the time setting in accordance with the method that suits your own lifestyle.

Do you use a phone?

Time adjustment by connecting with your phone is recommended.

Auto Time Adjustment

Your watch adjusts its time setting four times a day according to a preset schedule. If you leave the watch in the Calendar Mode, it will perform the adjustment operation automatically as you go about your daily life, without any operation required by you.

Important!

• The watch may not be able to perform auto time adjustment under the conditions described below:
• While the watch is too far away from its paired phone.
• While communication is not possible due to radio interference, etc.
• While the phone is updating its system.
• While EDIFICE Connected is not running on the phone.

Note

• If the watch does not indicate the correct time even if it is able to connect with a phone, adjust the hand and day indicator positions.
• If there is a World Time City specified with EDIFICE Connected, its time will also be adjusted automatically.
• The watch will connect with the phone and perform auto time adjustment at around 12:30 a.m., 6:30 a.m., 12:30 p.m. and 6:30 p.m. The connection is automatically terminated after auto time adjustment is complete.

Other than the above.

You can adjust time settings by performing operations on the watch.

2. Press (B) to reset the elapsed time to all zeros. To return to the Calendar Mode, reset the stopwatch to all zeros and then press (B).

Flyback Timing (Lap Timing)

A lap time is the time elapsed during a specific lap or segment. Lap times are recorded internally by the watch. The watch displays the elapsed time of the current lap.

Example: Recording a Race Lap Time

This section explains how to record lap times while watching a race. It also shows how you can view lap times with EDIFICE Connected after the race is over.

During a race Measure lap times.

1. In the Calendar Mode, press (A). This enters the Stopwatch Mode and starts an elapsed time measurement operation.

3. Press (B) to move the second hand to off. Each press of (B) toggles between on and off.
4. Push the crown back in.

Adjusting Hand and Day Indicator Alignment

Strong magnetism or impact can cause the hands and/or the day indicator to go out of alignment. If this happens, adjust hand and day indicator alignment.

Using EDIFICE Connected to Adjust Hand and Day Indicator Alignment If the watch is paired with a phone, you can also use EDIFICE Connected to adjust hand and day indicator positions.

Adjusting Hand and Day Indicator Alignment

1. Pull out the crown to the second click. This causes the second hand to move to 12 o'clock.
2. Hold down (B) for at least five seconds until the watch beeps. Release the button when you hear the beep. This causes the second hand to perform one full revolution and enables adjustment of second hand alignment.
3. Rotate the crown to align the second hand with 12 o'clock.
4. Press (B). This enables adjustment of hour hand, minute hand, and 24-hour hand alignment.
5. Rotate the crown to align the hour hand, minute hand, and 24-hour hand with 12 o'clock.
6. Press (B). This enables adjustment of small hour hand, small minute hand, and small 24-hour hand alignment.
7. Rotate the crown to align the small hour hand, small minute hand, and small 24-hour hand with 12 o'clock.
8. Press (B). This enables function hand and day indicator alignment.
9. If the function hand and/or the day indicator is out of alignment, rotate the crown to adjust them. Move the function hand to 12 o'clock and/or the day to the center of the indicator window.
10. The movement ranges of the function hand and day indicator are limited when you rotate the crown. The maximum left-right movement of the function hand is 180 degrees in either direction. The day indicator moves only slightly.
11. After the function hand and day indicator are in the positions you want, advance to step 12 of this procedure. If you are unable to make the adjustments you want, go to step 10.
12. Press (B). Confirm that the day indicator shows "1".
13. The function hand will move repeatedly while the day setting is being changed. The function hand may continue to move for about 20 minutes.
14. If "1" is not shown for the day, rotate the crown until "1" is shown for the day. Rotating the crown also causes the function hand to move. Move the function hand to 12 o'clock.
15. Push the crown back in.

Note Leaving the crown pulled out for more than approximately 30 minutes without performing any operation will automatically cause the adjustment operation to become disabled. If this happens, push the crown back in to its normal position and then pull it out again to restart the procedure from the beginning. Pushing the crown in to its normal position part way through the alignment procedure will cause the hands to return to their normal position. Any alignment you performed up to that point will be applied.
