The Watch S3 also has an accelerometer, gyroscope, electronic compass, barometer, ambient light sensor, and hall sensor. The raise-to-wake function works well and can save some battery life. You can also use the gimmicky customizable quick gestures by rotating or shaking your wrist to ignore a call or launch Alexa. There are a few other options, but the photo shortcut did not work for me, even using the Watch S3 with a Xiaomi 14 Ultra.
