When Google launched Android Wear 2.0, they said the ZenWatch 2 and 3 would get updated to the new OS. Later Asus announced both smartwatches should get the update in Q2 2017.
Now Asus has started seeding the highly-anticipated Android Wear 2.0 update for the ZenWatch 3. The information has been confirmed by Asus UK, which said it started the rollout earlier this week. The availability of the update should expand to additional countries in the coming days.
The ZenWatch 2 might receive the update by the end of this month.
