Newcomers like Pebble might be the current darlings when it comes to connected watches, but it doesn't mean that established players are standing still. Back at CES, Casio showed a G-Shock watch with Bluetooth (GB-5600A) capable of receiving calls and text-message notifications (with sound and vibration), plus automatic time updates from an iPhone. Today the company announced a pair of G-Shock watches (GB-6900B / GB-X6900B) with Bluetooth 4.0 LE that extend the existing functionality to select Android handsets. In addition, both watches feature music remote control (via AVRCP, presumably) and the ability to set alarms and timers from Casio's companion smartphone app. Battery life is a pretty impressive two years (with 12 hours of Bluetooth use per day) on a single CR2032 battery. The GB-6900B and GB-X6900B will be released in Japan on September 21st for 18,000 yen (roughly $187) and 20,000 yen (roughly $208) respectively. All that's needed now is a retro-looking Databank or calculator watch with Bluetooth, right, Casio?
