The GB6900AA collection provides Bluetooth time sync, alerts for incoming calls and emails, in addition to a Find Me function in which alarm and vibration functions on an iPhone can be activated using the buttons of the watch. To silence the vibration of the alarms, Casio has added a tap function in which the user double taps the face and the alert is automatically dismissed. In addition, the Bluetooth G-Shock will provide a notification when the phone is out of range of the watch, making sure the phone is never misplaced and the watch will automatically adjust itself to the correct time zone by using the time data received through the iPhone.
As smart phones become smaller and lighter, for the most part, wrist watches have become kind of redundant. Even special functions can be handled by apps, beyond simple time/date keeping. The G-Shock was announced last year, and one of the early watches coming to market that look to link with smartphones. Good idea. Essentially this lets users keep their phone in their pocket, but it's also interesting that it's a two-way symbiotic thing. The phone helps keep the watch's time accurate.
The G-Shock line is available in Black, Gray-Blue, Brown, and White. The watches retail for $180 and require an iPhone 4S or newer.
