Press and hold the up button, select "Watch Face," and choose from the pre-loaded options or download new ones from the Connect IQ store.

Wear the watch while you sleep. It will automatically track your sleep stages and provide insights in the Garmin Connect app.

The heart rate monitor provides reasonably accurate readings for most activities. However, it is not a medical device and should not be used for critical medical monitoring.

In the Garmin Connect app, go to the device settings and select "Activities & Apps." Choose the activity you want to customize and edit the data fields displayed on the watch.

The Garmin Instinct 3 has a water resistance rating of 10 ATM, meaning it is suitable for swimming, showering, and other water activities at depths up to 100 meters.

From the watch's menu, navigate to Settings > System > Reset > Reset Default Settings. Note this will erase all your custom settings and data.

Ensure the watch is charged. Try a different charging cable or outlet. If the issue persists, try a forced restart by holding the power button for 15 seconds.

Ensure you have a clear view of the sky when acquiring a GPS signal. Enable multi-band GPS for improved accuracy. Update the watch's software through the Garmin Connect app.

Ensure the watch is snug on your wrist. Clean the sensor on the back of the watch. Try moving the watch slightly up your wrist during workouts. Restart the watch.

Check that notifications are enabled in the Garmin Connect app. Ensure your phone is connected to the watch via Bluetooth. Restart both the watch and your phone.

Reduce screen brightness, disable features like Pulse Ox and smart notifications, and limit the use of GPS. Ensure the watch software is up to date.
