The Apple (NASDAQ:AAPL) Watch faces competition from a wide variety of wearable devices, yet Alphabet's (NASDAQ:GOOG) (NASDAQ:GOOGL) Android Wear may pose the greatest risk. Like Android smartphones, Android Wear watches are available in a wide variety of shapes, sizes, and price points, and are offered by many different manufacturers. They work best when paired with Android-powered smartphones but do support the iPhone in a limited sense.

The first Android Wear watches made their debuts last June, and since then, a dozen different models have been released. But going into the holiday shopping season, there are six Android Wear devices worth watching. The following slideshow offers a look at those six Android Wear watches and how they stack up against the Apple Watch.
