A new Sony accessory has passed through the FCC in the US with model number SWR10. The Bluetooth device is NFC-enabled, but we’re unsure exactly what the SWR10 is. The FCC documents have the term “BT Wrist Notifier” littered throughout them, which could signify it is a type of SmartWatch. However, we’d be surprised to see a new SmartWatch appear too soon. Maybe we’ll hear more from the CES 2014 tradeshow in a few weeks’ time – we’ll keep you posted.
