I use the Mobvoi TicWatch Pro 3 with GolfPad and I am very happy with performance and battery life. The watch operates with Wear OS 2.3 as Wear OS is announced only for mid 2022.
Anyway I don't need Wear OS 3 as the GolfPad App for Wear OS 3 has also limited features as the App for Wear OS 2.3. Features as club selection, putt out or standalone are promised, but we users still wait for the updated app having these features.
