Apple Watch Ultra 2 Review 2025

Design and Build Quality

The Apple Watch Ultra 2 is a masterclass in premium construction. The 49mm aerospace-grade titanium case is both lightweight and incredibly durable, capable of withstanding extreme conditions. The raised crown and side button are easy to operate even with gloves, while the new Action Button provides customizable functionality.

The flat sapphire crystal display is the brightest Apple has ever produced at 3,000 nits, making it easily readable in direct sunlight. The watch feels substantial without being overly heavy, though it's definitely larger than most smartwatches and may not suit smaller wrists.

Build quality is exceptional throughout. The titanium case shows minimal wear even after months of use, and the integrated band system ensures a secure fit during intense activities. The orange Action Button adds a distinctive touch while serving a practical purpose.

Performance and Software

Running on the S9 SiP (System in Package), the Apple Watch Ultra 2 delivers blazing-fast performance. Apps launch instantly, animations are smooth, and there's no lag during intensive workouts or when running multiple complications.

WatchOS 10 is optimized for the Ultra's larger display, providing more information at a glance. The always-on display is perfectly calibrated, automatically adjusting brightness based on ambient conditions. Siri processing is done on-device for faster responses and better privacy.

The Action Button is a game-changer, allowing quick access to workouts, flashlight, timer, or any custom shortcut. It's perfectly positioned and provides satisfying tactile feedback. The Digital Crown and side button are more responsive than previous generations.

Fitness and Health Tracking

This is where the Ultra 2 truly shines. GPS accuracy is exceptional, even in challenging environments with tall buildings or dense forests. The watch supports dual-frequency GPS for pinpoint location tracking during runs, hikes, and cycling.

Heart rate monitoring is remarkably accurate, matching chest strap monitors within 2-3 BPM during steady-state exercise. The blood oxygen sensor works reliably, and sleep tracking provides detailed insights into sleep stages and recovery.

The Ultra 2 includes specialized features for serious athletes: dive computer functionality for recreational diving up to 40 meters, precision tracking for running and cycling, and a waypoint system for navigation during outdoor adventures.

Workout detection is instant and accurate. Whether you're starting a run, beginning a swim, or lifting weights, the watch recognizes the activity immediately and begins tracking relevant metrics. Post-workout analysis is comprehensive, including training load and recovery recommendations.

Battery Life and Charging

Battery life is the Ultra 2's standout feature. In typical use with always-on display, GPS workouts, and all sensors active, it easily lasts 36 hours. With Low Power Mode enabled, it can extend to 72 hours while maintaining core functionality.

Fast charging is impressive - 0 to 80% in just 45 minutes using the magnetic fast charger. The Ultra 2 also supports the new double-tap gesture, allowing control without touching the screen, which helps conserve battery during long adventures.

For multi-day adventures, the watch can run in ultra-low power mode, functioning as a basic time and GPS device for up to a week. This makes it genuinely suitable for extended camping trips or multi-day hikes.

Connectivity and Smart Features

The Ultra 2 includes cellular connectivity (optional), allowing complete independence from your iPhone. Call quality is excellent thanks to the larger speaker and improved microphone array. Emergency SOS via satellite provides peace of mind during remote adventures.

Smart features are comprehensive: Apple Pay works flawlessly, notifications are clear and actionable, and third-party app support is extensive. The always-on display means you never miss important information.

Integration with the Apple ecosystem is seamless. Handoff works perfectly, allowing you to start activities on your watch and continue on your iPhone or iPad. Shortcuts automation opens up countless possibilities for customization.
