If you're more comfortable hiking mountain trails or gliding under water -- or you just prefer a chunky smartwatch with days of battery life -- your patience over the last couple of years has paid off. Apple today announced the Apple Watch Ultra 3, the next generation of its high-performance smartwatch. The Ultra 3 adds a brighter, larger display, 5G cellular communication, satellite connectivity, a battery life increase up to 42 hours and the ability to detect whether you might be suffering from hypertension. Apple Watch Ultra fans have had to spend a while watching time pass on their Ultra-exclusive Wayfinder face. The Ultra 2 arrived in 2023, but last year Apple merely added a new Satin Black color, even as the Apple Watch Series 10 gained a better processor and adopted a screen that became the largest in the line. Now the Ultra 3 is here to satisfy those who want the most smartwatch Apple can offer. The Apple Watch Ultra 3 costs $799 (£749, AU$1,399), with preorders starting today. The first shipments and in-store availability arrive Sept. 19. We're following today's Apple news closely to see how it compares to everything we expected to see. To learn about what's being released as it happens, including commentary and photos from the event itself, follow along with CNET's Apple event live blog.

Apple/Screenshot by CNET The Apple Watch Ultra 3 screen size is back on top The brilliant screen on the Apple Watch Ultra 3 is now slightly larger than its predecessor at a 422x514-pixel resolution (up from the Ultra 2's 410x502 pixels), though the case itself hasn't expanded. Instead, Apple has slimmed the bezel to bring the active edge of the screen closer to the frame. The screen is also better than the Ultra 2, with an LPTO3 OLED always-on Retina display that has the same faster refresh rate introduced with the Series 10. That means you'll see a second hand that continually updates, or an active stopwatch timer, without having to raise your wrist and engage the screen. Screen brightness when viewing from an angle has also improved, according to Apple. The Apple Watch Ultra 3 at the Apple Sept. 9 event. Vanessa Hand Orellana Even more battery life The Apple Watch Ultra and Ultra 2 boasted much longer battery stamina than the regular watch, thanks to its physically larger battery: about 36 hours of regular use or stretched out to 72 hours with Low Power mode turned on. With the Apple Watch Ultra 3, you might forget the last time you put it onto its charger, thanks to a larger battery and improved battery life that gets up to 42 hours on a charge. Continuous workouts can extend to 20 hours in Lower Power Mode while retaining full GPS and heart rate readings. The Ultra 3 also joins the Series 10 and Series 11 by offering fast charging. Apple claims 45 minutes of charging will get the watch up to 80% full, or 75 minutes to top out at 100%. Since most people probably aren't going to run the watch down to zero, a more realistic circumstance is being able to pop it onto a charger for just 15 minutes and gain 12 hours of battery life. Connect to satellite services, even without an iPhone Most phones and smartwatches are designed with the expectation that they operate in areas where cellular or Wi-Fi networks are easily available. The Apple Watch Ultra almost expects you to get lost, with its larger battery and dual-GPS location tracking. But if something unfortunate happens while you're away from everything, you still want to be able to signal for help or keep friends alerted to your whereabouts. The Apple Watch Ultra 3 now offers satellite SOS capabilities. Apple/Screenshot by CNET The Ultra 3 now includes on-device satellite communication, which means as long as the watch has a view of the sky, it can connect to satellites. In most situations you'd also have a satellite-capable iPhone with you, but that's not helpful if the phone's battery is drained. As with the iPhone, Emergency SOS via satellite is free for two years, though Apple has not announced any pricing for the service since it was launched. Text messaging and Find My services via satellite are also available. As for cellular connections, all configurations of the Apple Watch Ultra include cellular capabilities, and now the Ultra 3 is capable of connecting to 5G networks. Health and fitness features at the forefront As with the Apple Watch Series 11, the Ultra 3 also looks for possible hypertension based on readings it takes during the course of a month. Hypertension detection is currently under review by the FDA; Apple expects availability in 150 countries and regions this month. A bike rider wears the new Apple Watch Ultra 3 Apple/Screenshot by CNET Apple introduced Workout Buddy when it announced WatchOS 26 and iOS 26, a virtual companion that provides stats and encouragement while you're working out, such as on a bike ride, run or walk. (CNET's Vanessa Hand Orellana got details from Apple's team developing it.) As a watch designed for workouts, it's natural that the Apple Watch Ultra 3 brings Workout Buddy along for the ride/run/amble. This is a developing story. Check back for updates.
