Detailed Feature Comparisons
Design and Construction: The Ultra 3 retains the rugged titanium case and flat sapphire front glass but feels slightly more refined in finish. Both models are water resistant up to 100m, dust resistant with IP6X rating, and feature customizable Action Buttons for workouts or navigation.
Display Quality: The Ultra 3 has an upgraded 3000-nit display, which improves visibility under harsh sunlight or snow glare. The original Ultra remains very bright at 2000 nits but may be slightly harder to read in extreme light.
Processor and Performance: The S10 chip in the Ultra 3 delivers faster app loading and smoother animations, particularly noticeable in navigation and fitness tracking. The original Ultra is still fast enough for most tasks but shows more lag with newer watchOS features.
Battery Life: Both watches deliver about 36 hours of standard use, but the Ultra 3 can stretch further in Low Power Mode with up to 72 hours. This is a key advantage for multi-day hikes or long travel days without charging access.
Health and Fitness Tracking: The Ultra 3 introduces improved motion detection for fall and crash detection accuracy and slightly better temperature tracking for cycle and sleep insights. The original Ultra covers the same major health metrics but with less precision in data logging.
GPS and Navigation: Both watches feature dual-frequency GPS for superior accuracy in cities or mountain trails. The Ultra 3’s updated chipset locks onto satellites slightly quicker, which helps when starting outdoor workouts on the move.
Connectivity and Smart Features: Connectivity is nearly identical, with support for Cellular, Wi-Fi, and Bluetooth 5.3. The Ultra 3 benefits from more efficient power management, leading to slightly better battery life when streaming music or using LTE frequently.
Software and Longevity: The Ultra 3 will likely receive longer watchOS support, making it a better investment for users who want to keep their watch for five years or more. The original Ultra will still receive updates for a few years but may miss future exclusive features sooner.
