Should You Buy the Apple Watch Ultra 3?
For outdoor enthusiasts who need extra durability and advanced tracking, the Apple Watch Ultra 3 is currently a solid buy. It was refreshed in September 2025, and with the next update expected around September 2026, there is plenty of time before a successor arrives. The improvements over the prior Ultra are meaningful, particularly the larger display, satellite communications, and improved battery life.
Compared to the standard Apple Watch Series 11, the Ultra 3 offers better water resistance, a more rugged enclosure, and significantly longer battery life. However, it is also larger at 49mm and may not suit everyone. Those with smaller wrists or those who do not need the extreme feature set should look at the Series 11 instead.
Design and Materials
Apple has retained the familiar look of the Apple Watch Ultra with a 49mm aerospace-grade titanium case. The material is lightweight yet durable, providing corrosion resistance for water-based activities. The third-generation model is available in Natural Titanium and Black Titanium, with the black version featuring a diamond-like carbon coating for improved scratch resistance.
The case is made using 3D printing technology with aerospace-grade titanium powder, reducing material waste compared to traditional manufacturing. The Digital Crown has larger, coarser grooves for use with gloves, and the side button is also glove-friendly. A customizable Action button sits on the left side in a bright orange color, allowing quick access to workouts, compass waypoints, and other functions.
Durability is a hallmark of the Ultra series. The watch is certified to MIL-STD-810H for military-grade environmental testing, including temperature extremes, shock, vibration, and immersion. It operates from -4 degrees Fahrenheit (-20 degrees Celsius) to 131 degrees Fahrenheit (55 degrees Celsius). The flat sapphire crystal display is more scratch-resistant than the glass used on standard models.
Water resistance is another key differentiator. The Apple Watch Ultra 3 is rated WR100 and EN13319, making it suitable for recreational scuba diving to 40 meters. It can also handle kitesurfing and wakeboarding, activities not recommended for standard Apple Watch models.
Display
The Ultra 3 features an LTPO3 wide-angle OLED display with smaller bezels, increasing the viewable area to 1,245 square millimeters. The display is larger than the 46mm Apple Watch Series 11 and retains up to 3,000 nits of peak brightness. It also maintains that brightness at wider viewing angles, making it easier to see outdoors.
The always-on display now supports a ticking seconds hand that is visible without raising the wrist. Brightness can drop to 1 nit in dark environments, which is useful in movie theaters or while trying not to disturb others at night.
S10 Chip and Gestures
Under the hood, the Apple Watch Ultra 3 uses the same S10 chip found in the Series 11. While there are no performance gains over the S9 in the previous Ultra, the chip supports new gesture controls introduced in watchOS 26. Double Tap allows users to answer calls, stop timers, play or pause music, and more by tapping their index finger and thumb together. Wrist Flick is a new gesture that dismisses notifications or declines calls with a simple flick of the wrist.
Storage remains at 64GB, providing plenty of space for apps, music, and offline data.
Health Features
The Apple Watch Ultra 3 includes a comprehensive suite of health monitoring tools. It uses a third-generation optical heart rate sensor for real-time heart rate data, an electrical sensor for ECG readings, and LEDs and infrared for blood oxygen measurements. The watch can detect high, low, and irregular heart rhythms, with notifications sent to the user when anomalies are detected.
One of the new features is Hypertension Alerts. The watch does not measure blood pressure directly but uses heart rate data over a 30-day period to identify potential signs of hypertension. Users who receive an alert can then perform blood pressure measurements with a cuff for seven days to share with their doctor.
Blood oxygen monitoring is available, although in the United States the data is sent to the iPhone and displayed in the Health app due to an ongoing patent issue. In other countries, readings appear directly on the watch.
Sleep Apnea Detection uses the accelerometer to analyze wrist movements during sleep for signs of interrupted breathing. After 30 days, the watch can indicate whether symptoms suggest sleep apnea. The Health app now includes a Sleep Disturbances category for this data.
Other health features include fall detection, crash detection, and temperature sensing. The Apple Watch Ultra 3 can alert emergency services if it detects a hard fall or a severe car crash. Temperature sensors support menstrual cycle tracking and retrospective ovulation estimates, as well as providing water temperature data in the Depth app.
Activity Features
Like all Apple Watches, the Ultra 3 tracks daily movement, workouts, and exercise. The large display shows the three Activity rings and provides reminders to stand and move.
For outdoor use, the watch includes a Depth app that displays current depth, water temperature, time underwater, and maximum depth. The Oceanic+ app, developed with Huish Outdoors, can turn the watch into a dive computer with a Bühlmann decompression algorithm.
A dedicated Tides app provides high and low tide times, tide height, and sunrise/sunset data. The Compass app includes a digital analog face, elevation, incline, latitude, and longitude. Users can drop Compass Waypoints to mark points of interest, and the Backtrack feature uses GPS to guide users back to their starting point if they become lost.
Battery Life
The Apple Watch Ultra 3 offers up to 42 hours of battery life on a single charge, a six-hour improvement over the Ultra 2. In Low Power Mode, battery life extends to 72 hours, making it suitable for multi-day trips. Fast charging delivers 80 percent capacity in 45 minutes, and a 15-minute charge provides up to 12 hours of normal use.
This battery performance is enough for users to complete a full long-course triathlon without needing to recharge partway through.
Connectivity
The Ultra 3 features built-in cellular connectivity with 5G support, a first for the Apple Watch. It also introduces satellite communications for off-the-grid situations. Emergency SOS via satellite, Messages via satellite, and Find My via satellite are available when Wi-Fi and cellular are unavailable.
The watch includes a second-generation Ultra Wideband chip for Precision Finding of a misplaced iPhone and compatibility with digital car keys. Bluetooth 5.3, Wi-Fi, and an 86-decibel siren with two alternating patterns round out the connectivity options. The siren can be heard up to 600 feet away.
Dual-frequency GPS with L1 and L5 bands provides the most accurate location tracking of any Apple Watch, which is essential for athletes who need precise distance, pace, and route data.
Comparison With Series 11 and SE 3
The Apple Watch Ultra 3 is sold alongside the Series 11 and the more affordable SE 3. The Series 11 starts at $399 and lacks satellite connectivity, the siren, and the rugged casing. The SE 3 starts at $249 and omits the blood oxygen sensor and ECG app. The Ultra 3 remains the top-end option for users who need the best battery life, durability, and advanced outdoor features.
What's Next for the Apple Watch Ultra
Apple is already working on an Apple Watch Ultra 4, but the next generation is expected to bring only incremental upgrades. A new S12 chip with faster performance and potential health tracking improvements are likely, while major design changes are not anticipated until at least 2028. Noninvasive blood glucose monitoring remains a future possibility, but it is still years away.
Apple may also adopt LG Display's high-mobility oxide technology for a future Apple Watch screen, which could reduce power consumption. Touch ID integration has been rumored for future models, hopefully providing new convenience features for unlocking and authentication.
The Apple Watch Ultra 3 continues to define the premium smartwatch category for outdoor enthusiasts, and future updates will focus on refining the experience rather than reinventing it.
