Should I choose Galaxy 7 Watch or Pixel 3?

Verdict: Choose Google Pixel 3 (or an updated companion smartphone) first because the Samsung Galaxy Watch 7 requires an Android smartphone with at least Android 11.0 and 1.5GB of RAM to set up, operate, and sync data via the Galaxy Wearable app.

Choose the Samsung Galaxy Watch 7 for wrist-based health tracking and modern 3nm hardware, or the Google Pixel 3 for full handheld mobile computing and photography.

Prefer the Samsung Galaxy Watch 7 for modern wrist-based biometric tracking and navigation, as it features a cutting-edge 3nm Exynos W1000 processor, Bluetooth 5.3, dual-frequency L1+L5 GPS, a 1.5-inch Super AMOLED screen, and up to a 425 mAh battery with 15W wireless charging. In contrast, the Google Pixel 3 serves as a dedicated handheld smartphone with a 5.5-inch P-OLED display, a 12.2 MP primary camera, and a 2915 mAh battery supporting 18W wired charging. While the Google Pixel 3 satisfies the minimum Android 11.0 requirement to pair with the Samsung Galaxy Watch 7 by running Android 12 with 4GB of RAM, its legacy 10nm Snapdragon 845 processor has reached end-of-life status and lacks exclusive ecosystem features like ECG and blood pressure monitoring.
