Look, we've all been there. You're trying to check your rings or see who just texted you, and your Apple Watch is just... frozen. Dead. A high-tech paperweight strapped to your wrist. It’s incredibly frustrating because these things are expensive, and they’re supposed to "just work," right? But sometimes the software hangs, or a buggy app update sends the processor into a tailspin. Knowing how to do a hard reset on Apple Watch isn't just a troubleshooting tip; it’s a survival skill for anyone in the Apple ecosystem.
Most people get confused between a simple restart and a hard reset. Honestly, they aren't the same thing at all. A restart is like taking a quick nap. A hard reset—what Apple officially calls a "force restart"—is more like hitting the giant red panic button. You only want to use it when the screen is black, the touch interface is unresponsive, or the device is acting so glitchy that you can't even get to the power menu.
Why Your Apple Watch Froze in the First Place
Before we jump into the buttons, let’s talk about why this happens. Computers (and yes, that watch is a tiny computer) get stuck in "infinite loops." Maybe the heart rate sensor is trying to hand off data to the Health app, but the Bluetooth connection flickered. Or perhaps a third-party app isn't optimized for the latest version of watchOS.

Sometimes, it's just the weather. Extreme cold can make the battery voltage drop, causing the OS to seize up. According to Apple's own support documentation, the operating temperature for the watch is strictly between 32° to 95° F (0° to 35° C). If you're out skiing or sitting in a sauna, don't be shocked if the interface hangs.
Usually, the "Green Snake of Death" (that charging cable icon that won't go away) or a frozen Apple logo are the main culprits. If you see those, a standard swipe-to-power-off isn't going to save you. You need the nuclear option.
The Simple Steps to Force a Restart
Doing this is actually pretty easy, but timing is everything. You have to be firm. Hold down both the Digital Crown (the twisty dial) and the Side Button (the flat one below the crown) at the same time.
Keep holding.
Don't let go when the screen goes dark.

Seriously, keep holding them for at least ten seconds. You are waiting for the silver Apple logo to pop up in the center of the display. Once you see that logo, let go immediately. The watch is now rebooting its firmware from scratch.
It feels like an eternity when you're staring at a blank screen, but letting go too early just results in the watch staying off or trying to trigger an Emergency SOS call. If you see the SOS slider appear, you’ve probably let go of one button or didn't press them simultaneously. Try again.
A Quick Warning About watchOS Updates
There is one—and only one—time you should never do a hard reset. If you are in the middle of a watchOS update and you see that circle of progress dots around the Apple logo, keep your fingers off the buttons.
Interrupting a firmware update by forcing a restart can "brick" the device. This means the software gets corrupted halfway through, and the watch won't know how to turn back on. If that happens, you’re looking at a trip to the Genius Bar because the Apple Watch doesn't have a physical port for you to plug into a computer and fix it yourself at home.
What If the Buttons Don't Work?
So, you held the buttons and nothing happened. That's a different level of stress. Often, this isn't a software crash; it’s a deep battery depletion.
When an Apple Watch battery hits true zero, it doesn't always have enough juice to even show the charging icon. Put it on the magnetic puck and let it sit for at least 30 minutes. Don't touch it. Don't try to reset it every five minutes. Give it a half-hour of pure, uninterrupted power. Often, the watch will "wake up" on its own once it hits a 5% or 10% charge threshold.
If it's still unresponsive after a long charge, check the back of the watch. Sweat, lotion, and skin oils can build up on the sensors and the charging contact point. Wipe it down with a microfiber cloth. A little bit of grime can actually prevent the induction charging from working properly, making you think the watch is broken when it's really just hungry for power.
The Nuclear Option: Erasing the Watch Completely
Sometimes a hard reset fixes the freeze, but the watch stays "janky." It's slow. Apps crash. This usually means there's a corrupt file in the OS that a simple reboot can't flush out. You might need to go beyond a hard reset and actually wipe the device.
If you can access the settings:
- Go to Settings on the watch.
- Tap General.
- Scroll down to Reset.
- Tap Erase All Content and Settings.
If you can't even get into the settings because the screen is a mess, you can do this from your iPhone. Open the Watch app, go to the "My Watch" tab, tap "General," then "Reset," and "Erase Apple Watch Content and Settings."

This sounds scary, but it’s actually pretty safe. Your iPhone automatically creates a backup of your watch every time they are near each other. When you set the watch back up, you can just hit "Restore from Backup," and all your health data, watch faces, and app layouts will come back. It takes about 20 minutes, but it's often the only way to fix a device that is chronically freezing.
The Hidden "Power Reserve" Glitch
There’s this weird thing that happens with older models like the Series 4 or the original SE. Sometimes the watch gets stuck in "Power Reserve" mode—where it only shows the time in small green numbers and doesn't respond to anything else.
People often think they need to learn how to do a hard reset on Apple Watch to get out of this. In reality, you just need to hold the side button (not the crown) for about 10 seconds until the Apple logo appears. Power Reserve is a low-power state that disables almost everything. If the battery is too low, it will keep kicking back into this mode no matter how many times you reset it.
When to Call It Quits and See Apple
If you’ve done the hard reset, you’ve charged it for an hour, you’ve tried to erase it, and the screen is still black or stuck on a red "!" icon, it’s a hardware failure.
The Apple Watch uses a "System in a Package" (SiP) design. Everything—the processor, memory, and wireless chips—is sealed in a single block of resin. If a component fails, there’s no "fixing" it in the traditional sense. Even Apple usually just swaps the entire unit for a refurbished one rather than soldering new parts.
Check your coverage. Even if you don't have AppleCare+, some battery issues or specific screen defects are covered under extended quality programs. It's always worth checking the serial number on Apple’s support site before you decide to buy a new one.
Summary of Actionable Steps
- The Combo: Hold the Digital Crown and Side Button simultaneously for 10-15 seconds.
- The Trigger: Only release the buttons once the Apple logo appears.
- The Charging Rule: If it doesn't respond, charge for 30 minutes before trying the reset again.
- The Clean: Ensure the back of the watch and the charger are free of debris.
- The Last Resort: Use the Watch app on your iPhone to "Unpair" or "Erase" the watch if the freezing becomes a weekly occurrence.
Next time your wrist vibrates incessantly or the screen stays dark while you’re mid-workout, don't panic. Most of the time, the software just needs a hard shove to get back on track. Keep those two buttons held down, wait for the fruit logo, and you’re usually good to go.
