Why This Watch
The Ultra 4 keeps the titanium case and Action button of past Ultras, then pushes the display to 3,000 nits, dual-frequency GPS, and genuine offline maps with custom route creation. Training Load, VO2 max, running power, and satellite-based Emergency SOS round out a watch built as much for serious training as for the backcountry. It's still an iPhone-only watch, so it's not a fit if you're on Android, but for iOS runners who want real training data without leaving Apple's ecosystem, this is as good as Apple gets.
