So I was at the Apple store in Beijing a few years ago when the latest version of the iPhone was released, and to say that Chinese are excited about new tech products would be the understatement of the century. The line for the new iPhone was out the door and was basically backed up (down) to Shanghai. Likewise, I was recently in Hong Kong for the Apple Watch release and the excitement was the same, if not even more so. All that to say this: the Apple Watch is going to be an absolute monster in China.
But unfortunately for members of the Chinese armed forces, the Apple Watch (or any other wearable tech) will not be allowed. According to a report (in chinese) from the PLA Daily:
The moment a soldier puts on a device that can record high-definition audio and video, take photos, and process and transmit data, it's very possible for him or her to be tracked or to reveal military secrets.
A valid concern, I suppose.
