The Android 6.0 Marshmallow rollout has been slow for Android Wear. Some devices have received it — the original Moto 360 being one of them — but many more modern devices are still waiting. Thankfully, Huawei announced that its smartwatch is going to be getting the update today.
The Huawei Watch has a built-in speaker that has been dormant until now. The Marshmallow update will enable it, making this a huge update for this watch. The update also features new gestures, an updated Do Not Disturb mode, and more, but I suspect people will mostly be excited about the speaker.
If you want to check for updates, go to Settings > About > System updates and check to see if you got it. If not, you may have to wait a while for the rollout to reach you. Let us know when you get the update!
Update: Apparently the information was wrong, and Huawei announced the official date of March 10 for the Marshmallow rollout.
