Android Wear seems to be off to something of a slow start, with 720,000 in shipped units last year. The numbers come from Canalys, who notes that Android Wear devices accounted for around 15% of the 4.6 million "smart wearable bands" shipped in 2014.
It's little surprise to see the hotly-anticipated Moto 360 noted as the leading watch amongst Android Wear devices, with the also-round LG G Watch R handily outperforming the square original G Watch. The breakdown of sales for each Android Wear watch wasn't immediately available, but given the pricing and the "TiVo problem" explanation (it's hard to explain the benefits of a smartwatch over just a smartphone without really experiencing those benefits) it's not a shock to see more mundane fitness bands overwhelming the category.
The closest competition to Android Wear right now is Pebble, which has sold 1 million watches since launching in 2013. Of course, things will change dramatically in 2015 with new Android Wear devices and the heavily-hyped launch of the Apple Watch.
