Before using this watch
After unpacking, the following must be done before using the watch:
• Checking the power reserve 
see page 3a
For optimal performance, ensure your watch is fully charged prior to use. Refer to page 2bc for charging procedures and times.
• Setting the correct time and date for your locale
The time may be adjusted either manually (see page 8bc), or by receiving time information when connected with iPhone, a mobile
digital device, using the app available from the App Store (see page
6c).
This watch has a rechargeable cell which is charged by exposing the dial to light.
Expose the dial to direct sunlight regularly to charge the watch.
For details of charging, see page 2bc.
Band adjustment
We do not recommend attempting to adjust the watch band yourself. Special expertise and experience is required for proper adjustment. If not adjusted correctly, the band may become detached leading to an injury or loss of your watch. (Some retailers may supply a band adjustment tool with your purchase).
For band adjustment, we recommend you consult the retailer where the watch was purchased or your nearest Authorized Citizen Service Center.
Some repair shops may charge a nominal fee for adjustment if the watch was not purchased directly from them.
Protective stickers
Be sure to remove any protective stickers that may be on your watch (case back, band, clasp, etc.). Otherwise, perspiration or moisture may enter the gaps between the protective stickers and the parts, which may result in a skin rash and/or corrosion of the metal parts.

Charging your watch
This watch has a rechargeable cell which is charged by exposing the dial to light, such as direct sunlight or fluorescent lamps (refer to page 2bc for charging guidelines).
After taking off the watch, put it in a location where the dial is exposed to bright light, such as by a window.
For optimal performance, be sure to:
•Expose the watch to direct sunlight half a day at least once a week.
•Avoid leaving the watch in dark places for long periods of time.
Caution
•Do not charge the watch at high temperature (about 60°C/140°F or higher).
•If the watch is obscured from light by long sleeves frequently, supplemental charging may be needed to ensure continual operation. Refer to page 2bc.
When the watch reaches a low charge state (insufficient charge warning function)
When the power reserve becomes low, the second hand moves once every two seconds. This is the insufficient charge warning function. Be sure to fully charge your watch as outlined on page 2bc.
• When the watch is sufficiently charged, the second hand will move normally.
•If you do not charge the watch for 10 days or
longer after the insufficient charge warning movement has begun, the watch will be depleted of all power and stop.
Caution
•When in the insufficient charge warning state, the current time and date are indicated. However, other features and functions of the watch will not be available for use.

Caution when connecting to iPhone
•Connecting to iPhone requires a substantial amount of power, especially if receiving many notifications. Be sure to keep your watch fully charged when utilizing this feature.
•We recommend disconnecting with iPhone when not needed (see page 6a).
•Connecting feature does affect battery usage on your iPhone. Be sure to check the charge level of your iPhone.
Power save function
If your watch is not exposed to light sufficient for charging for 30 minutes or more, the second hand will stop in order to conserve power. Although the second hand is not moving, the correct seconds are stored in memory.
The power save function cannot be activated manually; it is an automatic feature only. The power save function does not operate under the following conditions:
•The crown is in position 
or 
.
•The current mode is Chronograph [CHR] or Calendar [CAL].
•The second hand is indicating a notification (“MAIL”/ “CALL”/ “LL”).
Canceling the power save function
The power save function is automatically canceled when the watch is exposed to light sufficient for charging. The second hand will then resume normal movement.
•The power save function will also be canceled if a notification is received from your iPhone. Note: the watch must be sufficiently charged and the dedicated app running on your iPhone in order to receive notifications.
•If the watch is in the power save state for long period of time, adjust
the time and date before use through the iPhone connection (see page 6c) or manually (see page 8b).
