Casio Japan have officially announced the release of the Bluetooth v4.0 enabled G-Shock GB-6900 smartphone compatible watches. These models were previewed early this year and various information has reached us here at G-Shockzone since, however Casio has confirmed they will hit retailers in Japan 'late December'.The main features of the G-Shock GB-6900 are as follows
*Sync watch time to smartphone time
*Audio and vibrate alert on watch for on incoming SMS
*Audio and vibrate alert on watch for on incoming call
*2 year battery life (assuming connected 12 hours per day)
*Alert for dropped bluetooth link
..and possibly more features once we see an English language version of the press release. Initially the GB-6900 is compatible with smartphones on Japanese network Docomo and Softbank - hopefully we will see more widespread compatibility in 2012.
The line up consists of three models, the black G-Shock GB-6900-1JF, the red G-Shock GB-6900-4JF and the white G-Shock GB-6900-7JF. All three will retail at ¥18900 which is approx USD$250 or GBP£160.
