This charging dock is suitable for use with the Zembro Oktave watch only. The charger of the Oktave watch comes with a built-in BLE (Bluetooth) beacon. The home BLE beacon provides additional home location positioning in case of unavailable GPS and also helps to optimize watch battery life. Please note that BLE beacon tracking services are not 100% accurate, it can only be used to approximate your at-home location. For more in depth indoor tracking we recommend using your Oktave in combination with additional BLE beacons (Link to BLE set in store). The dock ships with a standard USB-A cable but does not include a mains plug. The charging dock has a magnetic base to allow the watch to be easily connected to the charging pins and ensures easy charging setup. A full charge takes approximately 60 minutes.
