The Apple Watch Ultra 3 is Apple's premium smartwatch tailored for outdoor enthusiasts, athletes, and adventurers. Priced from $799, it sits at the top of the Apple Watch lineup, offering enhanced durability, extended battery life, and specialized features not found in standard models. Launched in September 2025, this third-generation model refines the Ultra formula with a larger display, satellite connectivity, and improved health tracking.
Key Specifications and Pricing
The Apple Watch Ultra 3 retains the 49mm titanium case but now includes slimmer bezels, increasing the viewable display area to 1,245 sq mm. The always-on LTPO3 OLED screen reaches 3,000 nits brightness and can drop to 1 nit in dark environments. It is available in Natural Titanium and Black Titanium finishes, the latter with a diamond-like carbon coating for scratch resistance. Pricing varies by band and configuration, with the base model starting at $799 for Alpine Loop, Trail Loop, or Ocean Band versions, and up to $899 for the Milanese Loop option.
Design and Durability
The design remains largely unchanged from the previous Ultra models, featuring a flat sapphire crystal display and a raised Digital Crown with deeper grooves for glove use. The aerospace-grade titanium case is 3D printed for strength and weight efficiency. The watch is MIL-STD-810H certified for extreme temperatures (−20°C to 55°C) and water resistant to 100 meters (WR100 and EN13319 certified for recreational diving to 40 meters). The international orange Action button on the left side is customizable for workouts, waypoints, or siren activation.
Display and Always-On Features
The upgraded LTPO3 display offers 24% thinner borders, enabling a larger screen without increasing case size. The always-on mode now includes a ticking seconds hand, and the display maintains high brightness at wider viewing angles. The modular Ultra watch face provides up to eight complications, and new Waypoint and Night Mode faces are added for 2025.
Performance and Chip
The S10 chip powers the watch with a 64-bit dual-core processor and a four-core Neural Engine. While performance is identical to the S9, it enables new gestures like Wrist Flick to dismiss notifications and Double Tap for one-handed control. Storage remains 64GB, sufficient for music, maps, and apps.
Health and Fitness Features
The Apple Watch Ultra 3 includes a full suite of health sensors: third-generation optical heart rate sensor, electrical heart sensor for ECG, blood oxygen monitoring (with limitations in the US due to patent disputes), temperature sensing, and accelerometer for fall and crash detection. New for this generation is Hypertension Alerts, which uses 30 days of heart rate data to detect signs of high blood pressure, and Sleep Apnea Detection that analyzes sleep disturbances over a month. Sleep Score provides a numerical rating of sleep quality.
Activity and Outdoor Tools
Beyond standard workout tracking, the Ultra 3 includes the Depth app for diving (up to 40 meters), a Tides app for ocean conditions, and an enhanced Compass app with Waypoints and Backtrack GPS. The Oceanic+ app (via Huish Outdoors) turns the watch into a dive computer. The siren emits 86 decibels and can be heard up to 180 meters.
Battery Life and Charging
Battery life is significantly improved: up to 42 hours in normal use (vs. 36 hours on Ultra 2) and up to 72 hours in Low Power Mode. Fast charging reaches 80% in 45 minutes, and a 15-minute charge provides 12 hours of use. The watch supports a 5-minute charge for 8 hours of sleep tracking.
Connectivity
All models include cellular (5G) and satellite connectivity for Emergency SOS, text messaging, and Find My when off the grid. Satellite features require an active cellular plan for messaging but emergency SOS works without one. The second-generation Ultra Wideband chip enables Precision Finding for iPhones and AirTags, and Bluetooth 5.3 is supported.
Comparison with Other Models
The Apple Watch Ultra 3 sits above the Series 11 (starting $399) and SE 3 (starting $249). The Series 11 lacks satellite connectivity, siren, and extreme durability, while the SE 3 omits blood oxygen, ECG, and temperature sensing. The Ultra 3 is the largest and most capable Apple Watch, but its 49mm size may not suit smaller wrists.
What's Next
Rumors suggest the Ultra 4 in 2026 could bring a redesign and improved hypertension monitoring, but no major changes are expected for the 2025 model. Noninvasive blood glucose monitoring remains several years away. The Apple Watch Ultra 3 is currently the best choice for those who need extreme performance and connectivity in harsh environments.
