The Casio G-SHOCK Bluetooth Low Energy Watch includes the following features: Time Correction from smartphone to watch (ensuring the watch always displays the correct time – anywhere in the world); Incoming Call, Email and SMS Alert notifications from smartphone to watch – including the ability to stop smartphone ring alerts from the watch; and a Finder Function that enables users to locate a misplaced phone by activating the alarm and vibration functions of their smartphone from a button-press on the watch.

The Nordic nRF8001’s class-leading ultra-low power performance enables Casio’s new G-SHOCK Bluetooth Low Energy Watch to offer a similar battery life to a conventional Casio wristwatch by being able to run from a single conventional CR2032 coin-cell watch battery for up to two years, while providing up to 12-hours per day of continuous wireless communication with Bluetooth v4.0-equipped smartphones and other devices.

The ability to use a coin-cell battery also means that the Casio G-SHOCK Bluetooth Low Energy Watch will weigh a similar amount (65g) to a conventional Casio G-SHOCK watch, and have a similarly small casing size (53.2 x 50.0 x 18.3 mm) – all crucial for a product designed to be comfortably worn by users for long periods.

Bluetooth low energy has been designed from the outset to extend Bluetooth wireless connectivity to compact, coin cell-powered devices such as watches. And Nordic has been at the forefront of the group that defined the Bluetooth low energy specification since becoming a foundation member of Nokia’s Wibree Alliance in 2006 (the Alliance became part of the Bluetooth Special Interest Group (SIG) in June 2007). Nordic contributed decades of expertise – gained in producing successive generations of class-leading proprietary and interoperable (ANT/ANT+) ULP wireless connectivity solutions within a field it pioneered.

"Bluetooth low energy opens the door to completely new ways of using watches as new applications are developed for smartphones," comments Etsuro Nakajima, Senior Manager within the Timepiece Division of Casio. "Although this will begin with allowing watches and smartphones to wirelessly communicate, our expectation is that over time a new category of watch product that we call ‘smart watches’ will evolve and be able to connect to the wireless networks of various kinds of devices that support Bluetooth low energy."
