Wear OS 6 is based on Android 16 and brings a Material 3 Expressive redesign, Watch Face Format 4 support, richer media controls, and Credential Manager authentication. It is no longer the newest platform: as of August 2026, Wear OS 7 is rolling out to eligible Pixel Watches. Wear OS 6 is still relevant on supported third-party watches, but availability depends on the exact model and manufacturer rollout.
Here are the confirmed features, compatible watches, and steps to check or install the update. Samsung’s Wear OS 6 software is called One UI Watch 8.
What’s new in Wear OS 6?
Google announced Wear OS 6 at Google I/O on May 21, 2025, initially as a developer preview. Google’s announcement highlighted Material 3 Expressive, updated watch-face tools, richer media controls, and Credential Manager authentication. The Android Developers feature guide describes the release’s supported capabilities.
Material 3 Expressive
Wear OS 6 introduces Google’s Material 3 Expressive design to the platform. It includes dynamic color, updated typography and shapes, edge-hugging buttons, more visible scroll indicators, expressive motion, and tile layouts that can support up to three columns. The extent of the visual changes depends on the watchmaker and the apps and tiles it updates. Updated Compose for Wear OS and ProtoLayout libraries also make the design system available to developers on Wear OS 3 and newer.

Watch Face Format 4
Wear OS 6 supports Watch Face Format version 4, a declarative format rendered by Wear OS. Its capabilities include user-selected photo collections, animated transitions between ambient and interactive modes, and Watch Face Push, an API intended to let watch-face marketplaces deliver faces through a host app.
Since January 2026, Watch Face Format is required for installing watch faces on Wear OS devices. Older faces and marketplaces may not install or work unless they support the format and its delivery method; Wear OS 6 does not automatically restore compatibility with every legacy face.
Gemini on supported watches
Gemini began rolling out to Wear OS watches in July 2025. It is not exclusive to Wear OS 6: Google says the rollout targets compatible watches running Wear OS 4 or newer, including models from Pixel, Samsung, OPPO, OnePlus, and Xiaomi. You can start it by saying “Hey Google” (where available), holding the watch’s side button, or tapping the Gemini app.
Gemini can answer questions and take actions involving services such as Gmail and Google Calendar when the relevant services and permissions are enabled. Google says an internet connection and setup may be required, and availability varies by device, country, language, account, and subscription.

Richer media controls and sign-in

Wear OS 6 also supports Credential Manager, introduced for Wear OS in version 5.1. Apps can use supported authentication methods such as passkeys instead of relying only on passwords or custom sign-in flows.

No. As of August 2026, Wear OS 7 is the current Google smartwatch platform and is rolling out to eligible Pixel Watch devices. Many third-party watches still run or are receiving Wear OS 6.
