Linking with your smartphone

Citizen Watch Official Application
CITIZEN Bluetooth Watch

Install the official app "CITIZEN Bluetooth Watch" to enjoy smartphone-based functions such as call and message notification, in addition to other functions that will enable you to get more out of your watch in a simple, intuitive way.

Key Functions
What can you do with the official app?

Home and Local Time
Get the time in any city in the world.

Via the link with your smartphone, your watch will automatically set itself to the time of the place where you are (“home time”). Meanwhile, inside the app, just tap a place on the world map or input a city name to set the watch to the time there (“local time”). The app covers 316 cities worldwide, including Coordinated Universal Time (UTC).

Set your alarm from your smartphone.

You can set your watch alarm simply and intuitively from inside the app. The alarm can be set for a different time every day of the week.

Message Notification
Find out when you get a mail, text or SNS notification.

The watch emits a sound, vibrates or rotates the hands to let you know when a new e-mail or Social Networking Service (SNS) notification has arrived. Select the apps from which you wish to receive notifications. Now you’re never out of touch.

※You can check which SNS apps are compatible from inside the official CITIZEN Bluetooth Watch app.

Call Notification
Find out when you get a call.

The watch emits a sound, vibrates or rotates the hands to let you know when someone is calling. A filter function enables you to specify which callers will trigger alerts. You will never miss a call from that special someone ever again!

Smartphone Search
Find your smartphone easily.

Mislaid your smartphone? That’s not a problem. Use your watch to locate your phone by getting the phone to emit a sound to indicate its whereabouts. (Range limitations apply to this function.)
When you’re about to forget your smartphone somewhere (in a café, for instance), the watch will warn you by emitting a sound, vibrating or rotating the hands to let you know when the link between your watch and the smartphone is broken.

Light Level Indicator
See how much light—and power—your dial is getting.

See how much power your watch is generating by checking how much light it is exposed to on a daily, weekly or monthly basis. CITIZEN is a pioneer in light-powered technology and this unique function reflects our special relationship with light.

Eco-Drive Light-powered Technology

No cable-based charging. No replacing batteries.

CITIZEN Bluetooth Watch charges from any kind of light. That means no need for replacing batteries or for cable-based recharging. CITIZEN’s proprietary light-powered technology, Eco-Drive generates power from any kind of light—from sunlight to dim light—to drive the watch, storing the surplus in a rechargeable cell. On a single full charge it can run for up to six months in total darkness.
