With Casio’s unique “smart watch”, you can be certain that your time is always accurate through automatic synchronization with your phone. In addition to this, it functions as a device that shows incoming calls, emails, and SMS on its display.
The big ‘show case’ feature on the Casio G-Shock GB-6900 is its use of the new Bluetooth LE technology which uses just a fraction of the energy of previous Bluetooth versions. Additionally, the device is blessed with great battery life of about two years with a conventional CR2032 button battery.
Personally, I think that 18,000 YEN (about US $231) is a lot to pay for a Casio watch, but I suppose if you have the cash to burn it could be a unique accessory that could appeal to some users.
