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.

Worst watch and app connection


This watch and app will not work at all times. It takes many times to connect to the app if you are lucky. I don’t wear the watch everyday and there is a disconnection and it takes many tries to try to connect. I had to call Citizen 4 times to help me correct the problem and each I had to reset the watch. Traveling to a different time zone or country forget abound connecting to the app. I want my money back or trade in for a different watch. I have another Citizen and it works well. Do not buy this watch.

Not happy at all 1974

Not impressed at all 197412345

Very nice looking watch but will constantly drop connection. Not recommended at all!

Functional but Pointless.


I’ve had this watch for 2 months now and find it’s use with an iPhone very lackluster. You can set the watch to vibrate for certain alerts on your phone like text messages, Facebook messenger, Snapchat etc. The watch will also vibrate for a phone call. You still have to look at your phone AND acknowledge the notification on the watch. This basically just adds another step in the users process. The Bluetooth doesn’t always connect easily and requires a phone reset. As a watch I love it. The face is easy to read and it can be synced to my phone for time. As an interface for notifications I find it gimmicky at best.
