Casio isn't shy to the idea of adding smart features to its line of G-Watches, but it hasn't reached the level of the high-tech smartwatches we see today (probably because it doesn't need or want to). By taking a relatively simplistic approach, Casio relies on Bluetooth for notifications. Now, by enhancing its Bluetooth functions, Casio is bringing something new to its smartwatch line. Rather than fitting the timepiece with various bells and whistles, the watch remains sophisticated in its craftsmanship while still being a hi-tech gadget. With the new G-Shock GBA-400 series, simple things like receiving message notifications, configuring watch settings from a smartphone app, plus a new added pleasure of Soundhound for controlling music playback are all possible.

You read that right. The GBA-400 uses a special trick to tell you what song is playing on its tiny LCD display. With Soundhound functionality, the watch can listen to the music playing around you, send it to your smartphone, then display the tune's name on your watch (similar to the way Shazam works). The huge rotary dial on the side of the watch is the user's mechanical gateway to the smartphone for notifications and the like. It is also where music playback can be controlled via G-Shock+ and G'Mix apps (both are free downloads and requirements for the watch's features).

Like previous Bluetooth-enabled G-Shock watches, the GBA-400 is equipped with low powered Bluetooth Smart technology. Casio claims the watch can run for 2 years, even with two hours of mobile link use a day. As with any G-Shock watch, this one is built for ruggedness. Impact resistant and water resistant (up to 20 ATM), this watch would work well for the outdoor and water sport enthusiasts. Those who prefer classier looking watches might feel the GBA-400 line is a little too bulky and serious looking. Compatible smartphones include iPhone iOS 7 or above, Samsung Galaxy running Android 4.3 or above, as well as unknown Japanese-specific devices. Casio's G-Shock GBA-400 series will be available in various colors for 23,000 yen ($224) starting September 19 in Japan, with no word of US or UK release.
