How they stack up

Google Pixel Watch 4

The Google Pixel Watch 4 offers over two days of battery life and built-in Gemini AI, which is more than the Apple Watch Series 11 or OnePlus Watch 3, but it lacks sapphire glass and restricts some features behind a paywall. Unlike the Garmin Venu 4, it doesn't provide advanced fitness metrics or recovery tracking, and while it's more affordable than the Samsung Galaxy Watch Ultra 2, it doesn't offer the same durability or health monitoring capabilities. The Apple Watch SE 3 provides better value with its updated design and speaker capabilities.

OnePlus Watch 3

The OnePlus Watch 3 delivers five-day battery life, which surpasses the Samsung Galaxy Watch Ultra 2 and Apple Watch Series 11, but it lacks the advanced health features found in the Garmin Venu 4 and Apple Watch Ultra 3. Unlike the Google Pixel Watch 4, it doesn't include built-in Gemini AI, and compared to the Xiaomi Watch 5, it lacks Wear OS 6 integration and smart features like YouTube Music. The Apple Watch SE 3 offers better value with its updated design and speaker capabilities.
