Apple Watch Series 12, 42mm, Black Aluminium Case, Black Sport Band, (GPS+Cellular)

Advanced Health and Fitness Tracking. Heartcore innovation.

The ultimate device for a healthy life just got healthier. Redesigned with more capable optical and electrical sensors, the all-new Health Sensing System works with the S11 chip to provide higher-frequency heart monitoring. Updated core sensors and larger, more power-efficient green LEDs give you richer heart data for more meaningful insights. So now you can really follow your heart.

HRV

With the most accurate heart rate sensing in a wearable, Apple Watch Series 12 measures HRV as often as every five minutes and takes background heart rate readings every five seconds — the most frequent sensing ever for Apple Watch. And with the updated Heart Rate app and new watch face complications, you can easily view your readings anytime.

Ready. Set. Know.

The new readiness experience can help you determine your capacity to take on the day by providing you with one simple score. Your score is determined each morning by analyzing your recent activity, vitals, and sleep — and it adjusts as you go about your day. So whether you’re training for a race or juggling a busy schedule, you can spend your energy on what matters most.

Sleep tracking. A wake-up call for your sleep.

Sleep quality is influenced by factors such as sleep duration, bedtime consistency, how often you wake up, and time spent in each sleep stage. Sleep score analyzes these factors every night and provides a classification and a score. You’ll see how the score is calculated, so you can understand the quality of your sleep and learn how to make it more restorative.

Witness your fitness like never before.

Tap into a world of workouts. Track your progress with a more accurate step count. Stay motivated with advanced metrics and new Workout Buddy insights. With all these features at hand, Apple Watch Series 12 is geared up to be a more powerful fitness tracker. It’s go time.

The Workout app. For all the ways you move.

From badminton and barre to swimming and cycling, Apple Watch has you covered in the Workout app. And you can make light work of your next strength training session by tracking your time, heart rate, and calories.

Your perfect running partner.

Apple Watch Series 12 helps you take your training further, from setting specific time and distance goals with Pacer to racing against your best times on your favorite runs with Race Route. It even recognizes when you’re at a track for more precise metrics with Automatic Track Detection. Want to tailor your run? Create a Custom Workout with a warmup period, recovery interval, and more.

Push your progress with enhanced Workout Buddy.

Get real-time encouragement right when you need it with new insights about your pace, distance, and workout progress. And you can finally leave your iPhone at home — all you need is Apple Watch with cellular.

Wearable AI Assistant

Say hello to Siri AI.

With all-new Siri AI, Apple Watch Series 12 can tap into broad world knowledge and your personal context to be even more helpful. Using just your voice, you can engage in natural, back-and-forth conversations, brainstorm ideas for workout routines, and get the latest wellness tips with Siri — all from your wrist. And now Audio Intelligence uses the built-in microphone and secure S11 chip in Series 12, alongside the power of Apple Intelligence, to help you make sense of what you hear in a private and secure way. Just like Visual Intelligence on iPhone helps you make sense of what you see. 

Shazam can now tell you what song is playing.

Shazam can detect the music playing around you and automatically display the song title and artist’s name on the Music Recognition widget in the Smart Stack — all without a tap. You can also see the song info when you use the Shazam app or Siri. Talk about music to your ears.

On the Go. Connected. Protected.

Series 12 makes it easy to call, text, and stream music with 5G. And it’s packed with innovative safety features, like Fall Detection and emergency services, so you can get help when you need it most — even if you can’t reach your iPhone.

Emergency SOS. ASAP.

Need urgent help ? Just press and hold the side button on your Apple Watch Series 12 to call emergency services and share your location.

Crash Detection. Your guardian on the go.
