Android Wear started off, as many Google products do, as something closer to a proof-of-concept than a finished product. The first watches had problems, the software was unfinished, and tech companies were the only ones producing them. Now that Android Wear is becoming a more mature platform, mostly thanks to the long-awaited 2.0 update, we're starting to see more watches than ever hit the market.

It was fairly easy to compare Android Wear watches in years past - only a handful of tech companies even bothered. But now, a vast amount of wearables are being released, with most of them by actual watch companies.
