Apple has announced the all-new Apple Watch Series 12 and Ultra 4 models, and here are the new features and key highlights.

New Apple Watch Series 12 and Apple Watch Ultra 4 Now Official with Big Focus on Health and Fitness

Both models go big in terms of health and fitness, according to Apple. This starts with the sensors behind the Apple Watch that have a larger area for better skin contact, which means more accurate vital readouts.

All-Day Heart Rate Measurements

Apple says these new watches take heart-rate measurements every 5 seconds throughout the day as long as you’re wearing your Apple Watch which is 60 times more often than the previous models. And, Apple says these new watches have the most accurate heart-rate sensing on any wearable out there.

Readiness

A new Readiness app goes through your important vitals like activity and sleep, and tells you whether you’re ready or not for the day or your workout. If something is off, Readiness will give you recommendations accordingly, allowing you to take useful action as needed.

New Intelligence Features

Audio Intelligence is a new feature that makes sense of the sounds around you. In other words, it’s very advanced sound recognition, allowing you to detect things like doorbells, alarms, and more, alerting the user immediately of something important as it happens.

There’s also a Live Rewind feature, which constantly listens to conversations around you, allowing you to see a transcript of everything that was said from a while ago. It’s all on-device and immensely private.

Siri Recap does exactly what the name suggests. You can turn it on all the time, or just set a schedule. Using the power of Siri AI, you will get a breakdown of everything that happened around you for that time or day.

New Powerful S11 Chip

The new S11 chip powers the new Series 12 and Ultra 4, and it offers performance derived from the A20 Pro chip from the iPhone 18 Pro.

Since you’ve already read about the new always-on features for Audio Intelligence, there’s actually a dedicated section on the S11 chip that handles these features, meaning it’s efficient on a hardware level.

Battery Improvements

Apple Watch Series 12 offers 24 hours of use on a single charge, while the Apple Watch Ultra 4 offers 50 hours of use on a single charge. Since both models feature faster wireless charging, you don’t have to worry about sitting next to a charger that often.

Price and Availability

Series 12 starts at $399, and Ultra 4 starts at $799. Both watches can be ordered today, and will be available to buy on the 18th of September.

Finishes and Colors

As usual, there are bunch of colors and finishes to choose from, including Ceramic. Writing them down here is only going to make everything boring. You can read more details about the Series 12 here, and Ultra 4 here.
