Apple Watch Ultra 3 with Satellite Messaging, 5G Support, and Sleep Score

Get ready for new adventures as Apple finally launched the Apple Watch Ultra 3 after two-year gap. Debuting at the Awe Dropping event, this beast is built tougher, smarter, and more connected than ever.

You will get sharper display, faster performance, 5G cellular, Emergency SOS via satellite, and advanced health features like hypertension alerts and Sleep Score. In this article, I will share all the specifications and features of Apple Watch Ultra 3.

Apple Watch Ultra 3 Display: Big, Bright, and Rugged

The Ultra 3 features Apple’s largest and brightest display yet, extending closer to the edges for an immersive look. It uses advanced wide-angle OLED technology and ultra-efficient LTPO3. This ensure you enjoy a faster 1Hz refresh rate in always-on mode without draining your battery.

Apple has also updated Stopwatch, Timer, and 20 watch faces to match the refresh rate so you can see the ticking seconds without raising your hand. I really liked the new Waypoint watch face. It includes a Live compass, satellite messaging complication, and Night Mode shortcut, perfect for adventures.

Built tough too with a sapphire crystal display (one of the toughest materials on earth) and a durable titanium case, it’s ready for anything you throw at it.

Hardware & Performance Upgrades

Under the hood, Apple used the same S10 chip, but the hardware boost is clear with brighter screen, better 5G, and improved GPS performance.

Battery life takes a massive leap up to 42 hours on a single charge, and up to 72 hours in Low Power Mode. When running out of juice, you can quickly plug it in for 15 minutes and get 12 hours backup. That’s serious staying power for extended adventures.

Emergency SOS via Satellite & 5G Support

The built-in two-way satellite communication is the star feature. So now, even when cell towers are unreachable, you can message emergency services, friends, and family or share your location. Moreover, if your watch detects an accident and you’re unresponsive, it will send an Emergency SOS via satellite. That’s adventure-ready peace of mind.

Plus, 5G cellular support ensures you can call, text, use apps, download media, or contact emergency services even when your iPhone is not with you. Apple has included an advanced algorithm to use two system antennas to boost the signal strength as well.

Health Features: From Sleep to Heart Alerts

The Ultra 3 now offers hypertension (high blood pressure) notifications, helping you catch early warning signs by analyzing heart-vessel responses over time. A nifty health alert on your wrist to detect serious chronic conditions.

On the other hand, the Sleep Score feature gives you an easy-to-understand breakdown of your slumber quality. It covers sleep stages like deep sleep, wake-ups, and consistency so you can actually improve how you rest.

It also keeps an eye on your breathing to track sleep apnea risk. And with the Vitals app, you get overnight stats like heart rate, blood oxygen, respiration, and wrist temperature all at a glance.

Fitness and Workout Updates in Ultra 3

The Apple Watch Ultra 3 takes workouts to a whole new level. It comes with super-accurate dual-frequency GPS, perfect for tracking runs, hikes, or rides with precision.

The new Workout Buddy acts like a personal coach, giving real-time audio feedback based on your performance. Moreover, the Workout app has been redesigned for quicker access to custom workouts, Race Route, and Pacer. Plus, Apple Music now auto-suggests playlists or podcasts to match your exercise vibes.

For sport-specific upgrades:

• Runners get advanced stride and pace data.
• Cyclists can track metrics and power with accessories.
• Swimmers can measure stroke, laps, and water temp.
• Hikers benefit from offline maps and Backtrack GPS.
• Divers can use Oceanic+ for scuba tracking.
• Golfers get pro-level insights with third-party apps.

watchOS 26 Features

The Apple Watch Ultra 3 runs on the brand-new watchOS 26, making it smarter and more fun to use. The interface gets a sleek new Liquid Glass design.

You’ll also see a smarter Smart Stack with context-aware tips, a handy Notes app right on your wrist, and even live translation in Messages for easier global chats. The cool wrist flick gesture lets you control alerts one-handed, and Smart Stacks hints lets you see what’s important quickly.

Apple announced the Watch Ultra 3 on September 9 along with the iPhone 17 lineup and Apple Watch Series 11 and SE 3.

You can pre-order the watch on September 12. It will officially start shipping and be available in stores beginning Friday, September 19, 2025.
