Apple has officially unveiled its next-generation smartwatches—the Apple Watch Series 12 and the Apple Watch Ultra 4. Announced at the “Surprise and Shine” event, these new wearables bring substantial upgrades under the hood, focusing heavily on advanced health tracking, battery life, and on-device AI capabilities.
Whether you are looking to upgrade your everyday wearable or seeking a rugged companion for your outdoor adventures, here is a complete breakdown of what Apple’s latest smartwatches have to offer.
Apple Watch Series 12: The Perfect Everyday Health Companion
At first glance, the Apple Watch Series 12 retains the sleek and familiar design of its predecessors, available in 42mm and 46mm sizes. However, the real upgrades are inside the case.
- Enhanced Battery & Charging: The Series 12 offers a solid 24-hour battery life for daily use, with a 25% bump in outdoor workout tracking (now up to 10 hours). Fast charging is better than ever—just 15 minutes on the charger yields 12 hours of extra battery life.
- New Finishes: The aluminum models come in dark bronze, black, light gold, and space gray. The titanium models feature radiant gold and natural titanium, while a brand-new ceramic version debuts in pearl white and night blue.

Apple Watch Ultra 4: Built for Peak Performance
Designed for athletes and adventurers, the Ultra 4 takes durability and endurance to the next level.
- A Battery You Can’t Outrun: Standard use now stretches up to a massive 50 hours, while Low Power Mode extends to 84 hours. For extreme athletes, the new Max Extended Workout mode tracks outdoor GPS and heart rate for up to 45 hours—enough to cover a 100-mile race.
- Sustainable & Rugged: Crafted from 45% recycled materials, including a 100% recycled titanium case, the Ultra 4 is available in natural and black titanium finishes. It retains its single, easy-to-read 49mm display size.
Groundbreaking Shared Features
Both the Series 12 and the Ultra 4 are powered by the new S11 chip and a radically redesigned Health Sensing System. Here is what makes them stand out:
1. The Most Accurate Heart Rate Tracking Yet
Upgraded optical and electrical heart sensors with larger green LEDs allow both watches to measure your heart rate every five seconds. Heart Rate Variability (HRV) is now tracked up to 24 times more frequently, providing deep insights into your stress and recovery levels.

2. The All-New “Readiness” Score
Catching up to dedicated fitness trackers, Apple introduces the Readiness feature. Every morning, the watch evaluates your sleep, vitals, training load, and recent activity to generate a score from 0 to 10. It then provides simple advice: Recover, Pace Yourself, Ready, or Go For It.
3. Audio Intelligence & Privacy
Thanks to the S11 chip, Apple brings Audio Intelligence to your wrist. Features rolling out later this year include:
- Sound Recognition: Alerts for alarms and doorbells.
- Live Rewind: Pulls up a quick text snippet of the last 15 seconds of a conversation.
- Siri Recap: Offers short summaries of discussions.
Apple emphasizes that audio is processed in an isolated hardware compartment and immediately deleted, ensuring your privacy remains intact.
Pricing and Availability
Both smartwatches are currently available for pre-order, with in-store availability starting Friday, September 18, 2026.
- Apple Watch Series 12: Starts at $399 (₹56,900 in India).
- Apple Watch Ultra 4: Starts at $799 (₹1,09,900 in India).
With the S11 chip, precise health sensors, and intuitive software, Apple’s 2026 wearable lineup offers compelling reasons to upgrade—especially for users highly focused on fitness data and battery longevity.
