If you're keen on joining the wearable technology revolution and snapping up one of the growing number of Android Wear smartwatches, make sure you check the specs first. 

That's because Google is about to push out two new software updates to the watches that will unlock some potentially very cool features. However, because they're dependent on hardware, not every intelligent timepiece currently on sale or waiting to come onto the market in time for Christmas will be able to support every new feature.
