Just like the original GB–6900, the new watches sync with your phone over Bluetooth 4.0, notifying you of incoming phone calls, new emails, and alarms. A warning function will let you know if you walk away from your phone, and a Find My Phone-like audio alert is available with a single button press. So far there is still no support for non-Japanese Android devices, but 4S (and, presumably, iPhone 5) owners with Casio’s G-Shock+ app (being released alongside the watch) will finally get to enjoy the Casio connected timepiece experience. The company hasn’t announced pricing or availability for the US, but the GB-6900AA and GB-5600AA will be available in Japan for ¥18,000 (about $230) in October and November, respectively.
