The Apple Watch Ultra offers a number of exclusive features not found on any other model of the wearable device.

We’ll explain how you can use the siren on the Apple Watch Ultra to call for help when you need it.

What Is the Apple Watch Ultra Siren?

When you activate the Apple Watch Ultra siren, the speaker will begin to play a continuous, 86-decibel siren that repeats at regular intervals. Apple says it can be heard up to 600 feet away.

The siren tone uses two distinct patterns that alternate and repeat. It will continue to sound until you turn the feature off or the Apple Watch Ultra runs out of battery.

How to Turn on the Apple Watch Siren

There are multiple ways to activate the Apple Watch Ultra siren.

First, press and hold the orange Action Button until the siren slider appears. Toggle it on by swiping to the right. After a short countdown, the siren begins.

You can even just long-press the Action Button to start the countdown and then keep holding the button until the siren starts. If you're worried about accidentally setting off the siren this way, it can be turned off by heading to Settings > Action Button on your Apple Watch. Toggle off Hold to Turn On.

Also, you can do the same thing by pressing and holding the Side Button. Make sure to see everything the Digital Crown and Side Button can do on all Apple Watch models.

Alternatively, you can just open up the Siren app on your Apple Watch Ultra. For a completely hands-free option, just say “Hey Siri, open the Siren app.”

Another quick way to stop the siren is to rest the palm of your hand on the screen for at least 3 seconds.

Use the Apple Watch Ultra Siren When You Need Assistance

While it’s something you’ll hope to never need, the Apple Watch Ultra Siren can easily tell anyone nearby that you need help.

The Siren tone is definitely loud and distinctive.
