Overview

This is the official app for linking your smartphone with CITIZEN Bluetooth watches (Bluetooth® version 4.0 or later). The app, which works with iPhone, enables you to set the time and the alarm for your watch, and to receive alerts for incoming calls, mails and texts. With CITIZEN Bluetooth Watch, you get to enjoy a handsome-looking analogue watch that tells the accurate time wherever you are plus the great convenience of a smartphone link.

CITIZEN Bluetooth features CITIZEN’s proprietary light-powered technology Eco-Drive. Eco-Drive eliminates the need of periodic replacement of batteries or recharge via cable.
 
Features 

1. Time Sync
Get the right time, all the time. When you connect with your smartphone, the time on your watch automatically updates to the current time (home time).

2. Local Time 
Get the time in any city around the world. Just touch the world map inside the app to set your watch to the time there (local time).

3. Call Notification
Find out when you get a call. The watch emits a sound, vibrates or rotates the hands to let you know when you get a call. A filter function enables you to specify which callers will trigger alerts.

4. 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 SNS notification has arrived. You can select the apps for which you wish to receive alerts.

5. Alarm
Set your alarm from your smartphone. Set your watch alarm using the smartphone app. The alarm can be set for different times for different days of the week.

6. Light Level Indicator
See how much light—and power—your dial is getting. Find out how much power your watch is generating by tracking the light it’s exposed to on a daily, weekly or monthly basis. This unique function reflects CITIZEN’s status as a pioneer of light-powered technology.

7. Smartphone Search
Find your smartphone easily. Mislaid your smartphone? Not a problem. Use your watch to locate your phone by getting it to emit a sound to indicate its whereabouts. (Range limitations apply.)

8. Link Loss Alert
Get alerted when you’ve forgotten your smartphone somewhere. The watch emits a sound, vibrates or rotates the hands to let you know when the link between your smartphone and your watch is broken.

This app requires iOS 9.3 or later.
Optimized for iPhone 5 or greater.
*Even if your smatphone is under the conditions above, there is no guarantee to use the dedicated app correctly on your smartphone.

About Eco-Drive:
Eco-Drive is a CITIZEN proprietary light-powered technology which eliminates the need of periodic replacement of batteries. Eco-Drive generates power from any kind of light—from sunlight to dim light—to drive the watch, and stores the surplus on a rechargeable cell. On a single full charge it can run for up to six months in total darkness*. For more details, click here.

### 1/5 — nuts

*2026-02-17, version 1.2.167*

this is so bad

### 1/5 — Awkward, frustrating to use

*2023-11-27, version 1.2.166*

App connects to watch, but it constantly pushes irrelevant pop-ups, “do you live in USA or Japan?” It will not accept no for an answer. 
App is awkward and not intuitive to use. It’s been on version 1 for five years, and this lack of manufacturer support really shows.

### 3/5 — これで良かったのに

*2023-10-05*

使えなくなってしまいました。
新しいアプリを使うにはリイィバーとかいうものに登録せねばならず非常に迷惑を被っています。

こっちのアプリが再度使えたら良いなあと思います。
腕時計自体も他のものに変えるか考えます。

### 1/5 — 新しく買った時計がBluetoothに接続出来ない。

*2023-02-26*

昨日新しくW410のメンズ時計がBluetoothに接続出来ないです。

### 1/5 — Doesn’t connect to my watch

*2022-06-21, version 1.2.164*

App is very frustrating. It just will not connect to my watch.

### 2/5 — Needs an update tho

*2021-04-09, version 1.2.149*

It was working great until I decided to buy a new Phone and the watch doesn’t even try to connect to my phone. 
It sucks tho

### 3/5 — 変わりましたね

*2021-04-07*

久しく本時計をiPhoneSEに繋いでませんでしたが、良好な動きで安定しています。

### 3/5 — Add Signal Messaging

*2021-03-29*

Please add signal messenger to the app for notifications.  App has the other major messaging services. Please fix the constant disconnection problem with the app everyone complains of.  It’s a great feature to get notifications when it works.

### 1/5 — Does not work

*2021-01-02*

Really sad, google involved with everything

### 2/5 — Connection

*2020-12-29*

The watch is great but the app is not. It keeps disconnecting my phone all the time. I tried everything, my phone was never more than 3’ away but to no avail. This watch should connect by itself whenever it loses connection, however I must reconnect manually, what a poor design. 
How am I supposed to know it lost connection?
Back to the drawing board please and fix this bug. My phone is an X model with the latest OS.
A nice feature is when the phone notifies an email arrive or a phone call is incoming. However this is a useless feature because the phone is always disconnected.
