Isn’t it a pain when you pull your smartphone out of your pocket just to check that new email, only to find that it wasn’t worth the effort? With Casio’s upcoming G-SHOCK watch, that won’t be a problem, because it’ll tell you who’s calling, texting, and emailing your smartphone; and a whole lot more.

Casio G-SHOCK GB-6900

It’s called the G-SHOCK GB-6900 and it’s set to launch on March 16 next year. At a glance, it looks a lot like any other Casio G-SHOCK watch, but it has one impressive feature that makes it a must-have for any smartphone user.

It connects to your smartphone via Bluetooth LE (low energy) to not only display incoming alerts for things like phone calls, text messages, and emails; but also to set new alarms, and silence your device’s ringer — all without taking your smartphone out of your pocket.

There is one downside, however: the GB-6900 uses Bluetooth 4.0 technology, which isn’t widely available on today’s smartphones. In fact, TechCrunch reports that the only devices it is currently compatible with are the Medias LTE N-04D and Medias PP N-01D Android handsets from NEC. That’s a huge shame in my opinion.

However, the upside to Bluetooth 4.0 is that it consumes a fraction of the energy of other Bluetooth versions. Not only does that mean it’ll have minimal affect on your smartphone, but Casio says the watch itself will run for around two years on just one CR2032 button battery.

The device was planned to launch in December of this year — in time for the holiday season — but was delayed until March 2012 due to the floods in Thailand. When it launches, it’ll cost 18,000 Yen (approx. $231).
