Apple Watch Series 12: Specifications of Apple’s New Smartwatch

The new Apple Watch Series 12 features the S11 chip and the Health Sensing System. Thanks to these upgrades, the watch measures heart rate every five seconds, checks heart rate variability up to 24 times more frequently, and calculates Readiness — a score from 0 to 10 that assesses the body’s readiness for physical activity. Another update involves artificial intelligence — the watch now includes Audio Intelligence features that recognize sounds around you.

When Was the Apple Watch Series 12 Released?

Apple Watch Series 12 was first unveiled at Apple’s presentation on September 9, 2026. Official sales of the new models have already started in Armenia. If you want to be among the first to learn about updates and exclusive iSpace offers, join our community and follow our social media.

Apple Watch Series 12 Design and Display

The 12th-generation Apple Watch retains its familiar shape and two case sizes — 42 and 46 mm. Ceramic has now been added to the aluminum and titanium options.

The watch features a wide-angle Always-On Retina OLED display. Its brightness ranges from 1 to 2,000 nits, so the screen is comfortable to view in the dark and remains readable in sunlight. Aluminum models are now protected by durable Ceramic Shield 2 instead of Ion-X, while titanium and ceramic models feature sapphire crystal. This reduces the risk of screen damage from accidental impacts.

Processor and Battery Life

The S11 chip powers the updated sensors and artificial intelligence features. Audio Intelligence capabilities include:

• Sound Recognition detects a fire alarm, a baby crying, or a doorbell and sends a notification — for example, if you are listening to music through headphones, a vibration on your wrist lets you know that you should pay attention. This is also important for people with hearing impairments;
• Live Rewind displays the text of the last 15 seconds of a conversation on the screen, allowing you to quickly check what the other person said if you got distracted;
• Shazam automatically identifies nearby music in the background and shows the track in Smart Stack. There is no need to tap the widget anymore;
• Siri Recap creates a brief summary of a conversation that can later be transferred to Notes — useful after a doctor’s appointment or a work meeting.

These features will become available in Armenia in 2026, but Siri Recap and Live Rewind currently support only English.

In normal mode, the device lasts up to 24 hours, while Low Power Mode extends battery life to up to 38 hours. During outdoor workouts, battery life reaches up to 10 hours, which is 25% longer than in the previous version. Fast charging is also available: 15 minutes on the charging puck provides up to 12 hours of use, while 5 minutes is enough for up to 10 hours of sleep tracking.

Health Features and New Sensors

The Health Sensing System has become one of the most significant updates. Apple has changed the optical and electrical sensors. As a result, heart rate is measured every five seconds throughout the day, providing more detailed data and making activity ring calculations more accurate. Heart rate variability (HRV) can now be measured up to 24 times more frequently than in the previous generation.

Readiness takes sleep, activity, workouts, and body metrics into account, then assigns a score from 0 to 10. It usually drops after a hard workout or poor sleep and rises as the body recovers. The score is updated throughout the day and helps you decide whether to choose an intensive workout.

The main Apple Watch Series 12 features remain unchanged:

• blood oxygen measurement;
• ECG (electrocardiogram);
• sleep tracking;
• high and low heart rate notifications;
• alerts about possible sleep apnea and hypertension.

The smartwatch is your personal assistant that helps monitor your health and better understand your body, indicating when you are ready for physical activity and when it may be better to rest.

The Health app on iPhone will also change later this year. The Longevity section will receive a Health Age metric, which compares selected health data with chronological age. If you notice a significant difference between the two, it may be a reason to pay closer attention to your health. To make this easier, the For You section will automatically suggest personalized content based on how you feel. The app will be supported on all iPhones with Apple Intelligence and the latest operating system.

Fitness and Workouts with Apple Watch Series 12

The new Apple Watch 2026 features a more accurate step counter. Machine learning algorithms have been updated in this generation, so distance is calculated correctly even when you walk or run indoors. Thanks to the new Steps complication, your step count is displayed directly on the watch face.

The Workout Buddy fitness coaching feature no longer depends on an iPhone if the watch is connected to Wi-Fi or cellular service in the GPS + Cellular configuration. It provides useful real-time tips during workouts, but currently supports only English and Spanish.

Connectivity and Compatibility

All models support Wi-Fi 4 and Bluetooth 5.3. You can choose between GPS and GPS + Cellular versions.

Apple Watch Series 12 comes with watchOS 27. Initial setup requires an iPhone 11 or later running iOS 27.
