There are many ways to go about getting your hands on an Android Wear device, but if your preferred method consists of ordering from the Google Store, there are two fewer options for you to consider. The original Moto 360 and the Sony SmartWatch 3 are no longer showing up for sale on the site.
You can still visit the webpages for both of these Android-powered smartwatches, but you will encounter a grayed out Not Available button when you do. Click it all you want. Nothing will happen.
Motorola replaced the Moto 360 with a 2nd gen model nearly half a year ago, so no surprise there. This isn't too unexpected from the SmartWatch 3 either, considering it went on sale back when the Google Store was a section on Google Play. But without a SmartWatch 4 available, the news is a bit sad.
