If your Apple Watch detects that you're moving, it waits for you to respond to the alert and won't automatically call emergency services. If your watch detects that you've been immobile for about a minute, it will make the call automatically.
Make an emergency call Do one of the following: Press and hold the side button until the sliders appear, then drag the Emergency SOS slider to the right. Your Apple Watch calls the emergency services in your region—for example, 911. (In some regions, you may be required to press a keypad number to complete the call.)
First, let's learn how the Apple Watch initiates an SOS. When you press the side button on your Apple Watch, the emergency SOS screen appears. Continue holding the side button, and a countdown will begin. At the end of the countdown, or if you slide the Emergency SOS slider, 911 will be called.
No, the Apple Watch will not call 911 if your heart stops. The Apple Watch can alert you to high or low heart rates and irregular heart rhythms through its notifications feature, but it cannot detect a heart attack or alert someone if your heart stops.
If your watch detects that you have been immobile for about a minute, it will make the call automatically. After the call ends, your watch sends a message to your emergency contacts with your location letting them know that your watch detected a hard fall and dialed emergency services.
On iPhone 8 or later, your iPhone can automatically call emergency services. When Call with Hold or Call with 5 Presses is turned on and you try to make an emergency call, your iPhone begins a countdown and sounds an alert. After the countdown ends, your iPhone automatically calls emergency services.
To place a call using the Apple Watch, a user must press and hold the watch's side button — located below the Digital Crown button — until the Emergency SOS slider appears. After the user drags the slider, a countdown begins. Once it ends, the call to 911 is placed automatically.
Will Apple Watch call 911 if my heart rate is above 150? No, Apple Watch will not call anyone regardless of whatever your heart rate may be.
In June, a police department in Kansas complained that accidental triggering of such calls by the Apple Watch are pulling responders away from genuine emergencies. The Emergency SOS feature will automatically make a call to first responders if the side button is held for a period of time.

If you hold down the side button on the iWatch, it will call 911 with a Wireless Phase 2 location (approximate location of the watch-wearer). For this feature to work, the watch-wearer must be within a Bluetooth connection range to their cell phone or connected to a stronger Wi-Fi.
With this feature, quickly pressing your watch's Home key (Power key) will send alerts and calls to your assigned emergency contacts.

On your Apple Watch, find the small oval shaped button on the right of the device directly below the crown. Press and hold this button until it beeps. A countdown will start, and when it ends the Apple Watch will contact emergency services.
To stop 911 from being called, tap Yes on the End Call screen. If you do accidentally call 911, stay on the line to let them know it was a mistake or they'll need to come check on you to make sure all is well.
