After the first three smartwatches got the Android Wear 2.0 update, Google had to halt the release to more Android Wear wearables because of a last-minute discovery of a bug. Thankfully, Google was able to fix that quickly and rolled out the new operating system to six more watches, which includes the Fossil Q Marshal, Fossil Q Wander, Michael Cors Access Bradshaw, Michael Cors Access Dylan, Nixon Mission, and Polar M600. This means nine out of the 19 devices expected to get Android Wear 2.0 have already gotten the update. Unfortunately, older generation Android Wear watches won’t be getting the new OS.
