Overview

The ultimate Apple Watch for your health.

The Apple Watch Series 12 is an even more powerful health and activity tracking tool. Understand your body better with the most accurate heart rate measurement on a wearable device1, with high-frequency HRV readings to provide insights into your stress level and recovery, hypertension notifications2, cycle tracking3 and Sleep Score4. Stay motivated with Readiness, advanced workout data and features like Pacer, Heart Rate Zones and more.

Key features:

  • KEEP AN EYE ON YOUR HEART HEALTH – With the most accurate heart rate measurement on a wearable device1, Series 12 now checks HRV every five minutes to provide insights into your stress and recovery, and measures your heart rate in the background every five seconds.
  • COMPREHENSIVE HEALTH TRACKING – Understand your body better with valuable health data. View your overnight health data with the Vitals app4 and get a Sleep Score every morning, track your menstrual cycle3 and measure your blood oxygen level5.
  • CHECK YOUR READINESS FOR THE DAY – Discover when to give it your all and when to rest.  The Readiness experience helps you assess your ability to take on the day by analysing your recent activity, vital signs and sleep.
  • POWERFUL ACTIVITY TRACKING – With advanced data and motivating features like Pacer, Heart Rate Zones and more, Series 12 helps you stay active, from running and hiking to strength training.
  • HELP ALWAYS AT HAND – A smartwatch that makes your safety a priority. Series 12 can detect a hard fall or a severe car crash, then automatically connect you to emergency services and alert your emergency contacts6.
  • ENJOY ALL-DAY BATTERY LIFE – Up to 24 hours of normal use so you can keep enjoying your favourite activities7. And 15 minutes of fast charging gives you up to 12 hours of normal use8.
  • BUILT TO LAST – The aluminium cases of Apple Watch Series 12 now feature Ceramic Shield 2, which is more durable than the glass on any smartwatch. The titanium and ceramic cases feature an ultra-robust, crack-resistant sapphire crystal display.
  • STAY CONNECTED – Series 12 (GPS) works with your iPhone or a Wi-Fi network to help you stay connected. Use your smartwatch to send a message, take a call, listen to music, use Siri and receive your notifications.


1 Based on an Apple study on heart rate measurement accuracy, August 2026. Visit apple.com/fr/HRAccuracy.
2 Hypertension notifications are not intended for people under 22, people previously diagnosed with hypertension or people who are pregnant.
3 The Cycle Tracking app should not be used for contraceptive purposes or to diagnose a medical condition. Cycle deviation notifications, including during perimenopause, are intended for people aged 40 and over.
4 The Vitals app is intended solely for wellness purposes and is not intended for medical use.
5 The Blood Oxygen app is intended solely for wellness purposes and is not intended for medical use. Data is calculated and displayed in the Health app on iPhone. The Blood Oxygen app is available on Apple Watch Series 6 and later models (except Apple Watch SE models) and on all Apple Watch Ultra models.
6 Emergency SOS requires a cellular connection or Wi-Fi Calling with an internet connection from your Apple Watch or nearby iPhone. You can use cellular Apple Watch models to call emergency services in many locations, provided that cellular data service is available. Some cellular networks may not accept emergency calls from your Apple Watch if it is not activated, if it is not compatible with a specific cellular network or is not configured to operate on that network, if it is not configured for cellular data service or if the cellular network does not support emergency calls over IMS. For more information, visit support.apple.com/fr-fr/108374 and apple.com/fr/watch/cellular.
7 Battery life varies depending on configuration and use. For more information, visit apple.com/fr/watch/battery.
8 Testing conducted by Apple in July and August 2026 using pre-production Apple Watch Series 12 (GPS) and Apple Watch Series 12 (GPS + Cellular) paired with an iPhone. All devices were tested with pre-release software and the Apple Watch Magnetic Fast Charger to USB-C Cable (model A3277) and Apple 20W USB-C Power Adapter (model A2305). Charge time varies depending on the adapter used, geographic area, settings, initial battery level, usage and environmental factors. Actual results may vary.
