The display is the defining feature of Apple Watch, and Series 4 pushes it further than ever. The challenge was to make it bigger without noticeably increasing the size of the case or compromising the battery life. Narrower borders enable a viewing area that’s over 30% larger, while a new display technology called LTPO improves power efficiency, helping you get through the day on a single charge.
A better experience all the way around.
Curved corners precisely match the radius of the case, creating a more pleasing, continuous appearance. This also allows imagery and the touch surface to extend to the farthest reaches of the screen.
More information in every millimeter.
To take full advantage of the new dimensions of the display, the entire interface has been redesigned to provide more information with richer detail. The new Infograph watch face can accommodate up to eight complications, so you can see more and do more at a glance.
Digital Crown. A breakthrough reborn.
The Digital Crown was invented to provide an easy way to navigate on Apple Watch without obstructing the display. With Apple Watch Series 4, the mechanism has been totally re-engineered. Haptic feedback now delivers a precise, click-like feel as you scroll.
A miracle of miniaturization.
Already one of the most intricate systems Apple has created, the Digital Crown on Apple Watch Series 4 adds even more capability into significantly less space. The entire assembly is 30 percent smaller, yet it includes 21 percent more components.
Keeps an eye on your heart.
The optical heart sensor has been part of Apple Watch from the beginning, allowing you to quickly check your heart rate. Now it can also detect if your heart rate falls below a specified threshold for a period of 10 minutes when you appear to be inactive, triggering a low heart rate notification. This can be a sign of bradycardia, which can be serious if the heart is not pumping enough oxygen-rich blood to the body.
Built with your heart in mind.
Apple Watch Series 4 regularly monitors your heart throughout the day, so you can check your heart rate anytime and keep track of your heart’s performance. What’s more, if it detects unusually high or low heart rates, it alerts you — even when you don’t feel symptoms.
On alert. So you don’t have to be.
High or low heart rates could be signs of a serious condition. But many people don’t recognize the symptoms, so the underlying causes often go undiagnosed. Apple Watch Series 4 checks your heart and alerts you to these irregularities — so you can take immediate action and consult your doctor.
Track all your health data in one convenient place.
All your heart data, as well as information from your health and fitness apps, is collected in your iPhone Health app. Activity, sleep, mindfulness, and nutrition are highlighted there in one snapshot.
Fall detection.
With the new accelerometer and gyroscope, Apple Watch Series 4 can detect that you’ve fallen. When an incident like this occurs, a hard fall alert is delivered, and you can easily initiate a call to emergency services or dismiss the alert. If you’re unresponsive after 60 seconds, the emergency call will be placed automatically and a message with your location will be sent to your emergency contacts.
Emergency SOS.
Emergency SOS allows you to summon help, right from your wrist. It calls for assistance, notifies your emergency contacts, sends your current location, and displays your Medical ID badge on the screen for emergency personnel.
Fill your lungs. Clear your mind.
Taking moments throughout the day to stop, relax, and practice mindfulness can help reduce stress and improve overall health. The Breathe app keeps you centered by taking you through a series of calming breaths. It’s now available as a watch face, so you can bring focus to your day just by raising your wrist.
Ready for whatever moves you.
Whether it’s training for a marathon or swimming laps at the pool, Apple Watch Series 4 has something for everyone. Now including yoga and hiking, the Workout app works every way you want to exercise. You can set individual goals, measure your calorie burn, and track your progress over time in the Activity app on your iPhone. Ready? Go.
Big steps forward for runners.
With a gentle tap, new pace alerts let you know whether you’re ahead of or behind where you want to be. The new cadence metric lets you see your steps per minute. And rolling miles allows you to see your split for the preceding mile at any time.
Connected gym.
With just a tap, you can pair your watch with compatible gym equipment.1 So you can keep important metrics like heart rate, speed, and calories in sync between your watch and the treadmill, stair climber, or stationary bike you’re on.
Automatic workout detection.
For most popular workouts, Apple Watch senses when you’re moving and alerts you to start the Workout app. It even gives you credit for the exercise you’ve already started. It will also remind you to end your workout, in case you get distracted when you’re cooling down.
Sweat, surf, and swim proof.
Apple Watch Series 4 is water resistant to 50 meters and tracks both pool and open-water workouts.2 Turn the Digital Crown to eject water from the speaker using a burst of sound.
Put your game face on.
With room for eight complications, the new Infograph watch face can reflect whatever you’re into, in richer detail than ever. Create your own custom workout face by adding complications like Music, Heart Rate, or whatever else gets your pulse going.
Music and podcasts to keep you moving.
Whether it’s an Apple Music album or playlist, an episode from Apple Podcasts, or a track from Beats 1 radio, you have all the motivation you need right on your wrist.
Challenge yourself by challenging a friend.
Apple Watch lets you share your activity progress from the trail, the track, or even the surf lineup. And now, new Activity competitions let you invite a friend to a seven-day contest where you earn points based on the percentage of your daily Activity rings you close.
A little coaching goes far.
During a competition, notifications will tell you if you’re ahead of or falling behind your competitor, along with the score. So you’ll know exactly how much you need to move to take home bragging rights. And like a personal trainer, Apple Watch will give you a nudge to close your rings at the end of each day, as well as offer up a new challenge each month.
Hardware for your hard work.
Now you can pick up a trophy when you seize a victory. You’ll find your competition award in the new Awards tab inside the Activity app on your iPhone.
Staying connected is easy.
Take calls, send texts, listen to voicemail — Apple Watch Series 4 let you do it all right there from your wrist.
Emergency SOS. A lifeline on your wrist.
Can’t reach your phone? Emergency SOS summons help right from your watch. It calls 911, notifies your emergency contacts and sends them your location, and displays your Medical ID badge on the screen for emergency personnel.
Say hello to Walkie Talkie.
Quicker than a call. More personal than a text. The Walkie-Talkie app lets you communicate in a fun, new way with anyone who has an Apple Watch. Just press to talk. Let go to listen. Roger that?
If you need it, Siri is on it.
As the Siri watch face gets to know you, it can proactively make suggestions at the right time and place — like ordering your morning coffee.
A view with more room.
Thanks to the larger display on Apple Watch Series 4, you get more information and richer detail at a glance than ever before. Maps are bigger, stretching from curved corner to curved corner. Calendars are even more comprehensive and helpful.
