Apple's iWatch
Wearable computing devices such as Google Glass eyewear are widely seen as the next frontier in consumer electronics, following the huge popularity of smartphones.
Competition in the "smartwatch" market is heating up, with Google, Microsoft and Samsung Electronics racing to develop their own watch-type computing devices.
California-based Apple last month filed a trademark application for an "iWatch" in Japan.
Apple chief Tim Cook earlier this year forecast that there will be "tons of companies playing" in the wearable computing sector.
