If you are here, you want to know that: BlueWatcher supports GBA-400!

At the end of 2014, CASIO released a music-themed model called G-Shock GBA-400 (G'MIX)

GBA-400 is a Bluetooth enabled watch that offers advanced music control features. The big difference is the big rotary switch at 3 o’clock that can be used to jump between songs, control the music volume...

Announced features are:

  • Change watch settings from your phone.
  • Control G'MIX music player from your watch.
  • Search for a song using SoundHound. Pressing a watch button, your phone recognizes a song.

Previous CASIO Bluetooth watches (GB-5600, STB-1000, GB-6900) offer more specific "SmartWatch" features like incoming call alert, email notifications, Facebook notifications. When an incoming call rings your watch can notify you vibrating, sounding and showing a message in the screen. Using BlueWatcher, GB-5600/STB-1000/GB-6900 models become a REAL SmartWatch.

It seems that CASIO decided to remove useful features from GBA-400 model and support more MUSIC capabilities. 

Which features do not implement GBA-400?

Next points are features that the watch do not include:
  • Notifications: GBA-400 does not alert you when an incoming call rings, an email arrives, etc.
  • Vibration: GBA-400 does not vibrate!!
  • No fixed connection: When you connect GBA-400, if you do not touch any button in some hours, the watch disconnects from the phone automatically.
  • No reconnection: If your connection breaks down, the watch does not try to reconnect again.
  • Can't configure multiple phone control modes to allow user to execute more than 5 phone commands.

In short, if you use G-Shock+ official app you will have an advanced music controller in your wrist! Forget receiving notifications or controlling advanced features from your wrist!
