# Apple launches Watch Series 12 and Ultra 4 smartwatches

Apple has unveiled its latest smartwatch lineup, introducing the **Apple Watch Series 12** and **Apple Watch Ultra 4** at its September 2026 event. The new models focus on health monitoring, fitness tracking, battery life and AI-powered features.

Both watches are powered by Apple's new **S11 chip** and feature an upgraded health-sensing system designed to provide more frequent and accurate heart-rate and heart-health measurements. Apple says the new system can provide heart-rate readings as frequently as every five seconds.

### New health and fitness features

One of the biggest additions is a new **Readiness** metric, which uses health and activity information to help users understand how prepared they may be for the day. The watches also introduce a **Health Age** feature and additional wellness insights through Apple's updated Health app.

Apple has also introduced **Audio Intelligence**, bringing AI-powered capabilities to the watches. Features include **Siri Recap**, which can summarize conversations, **Live Rewind**, which can transcribe recent speech, and enhanced Sound Recognition. Apple says these features are designed with privacy protections, with audio processing handled on-device.

### Series 12 gets new designs

The Apple Watch Series 12 starts at **$399** in the US for the aluminum model. Apple has also brought back ceramic cases, with premium versions starting at $899. Titanium versions start at $699.

The Series 12 offers up to **24 hours of everyday battery life**, while faster charging can provide up to 12 hours of use after 15 minutes of charging.

### Ultra 4 targets demanding users

The **Apple Watch Ultra 4** continues Apple's rugged smartwatch line, featuring a titanium design and a battery rated for up to **50 hours** of normal use. It starts at **$799** in the US and is available in natural and black titanium finishes, alongside Hermès editions.

In India, the Series 12 starts at **₹56,900**, while the Ultra 4 starts at **₹1,09,900**, according to launch reports. Both models are available for preorder, with retail availability beginning **September 18**.

With the Series 12 aimed at everyday users and the Ultra 4 targeting athletes and outdoor enthusiasts, Apple is positioning its newest watches as more health-focused and intelligent companions, while continuing to build on the company's growing wearables ecosystem.
