Detailed Feature Comparisons
Design and Build: The Ultra 3 uses a titanium case with a flat sapphire front that offers exceptional scratch resistance. It looks rugged and is designed to withstand extreme conditions. The Series 11 has a sleeker profile with aluminum or stainless-steel options, making it a lighter and more fashion-oriented choice.
Display Quality: The Ultra 3 features a 49mm Retina display reaching 3000 nits, which is very useful for reading in bright sunlight or underwater. The Series 11 offers 41mm and 45mm displays with up to 2000 nits, which is bright enough for everyday use but slightly less visible under harsh sunlight.
Battery Life: The Ultra 3 delivers up to 36 hours of standard use and 72 hours in Low Power Mode, making it ideal for multi-day adventures. The Series 11 manages 18 hours of standard use, suiting daily charging habits but less convenient for extended trips without power access.
Durability: The Ultra 3 is certified for WR100 water resistance and EN13319 for recreational diving, making it suitable for ocean activities up to 40 meters deep. The Series 11 remains swimproof but is limited to WR50, better suited for pool or shallow-water workouts.
Performance: Both models share the S10 SiP chip, so app performance and responsiveness are nearly identical. However, the Ultra 3 is optimized for power efficiency to stretch its longer battery life during intensive tracking.
Fitness and Outdoor Features: The Ultra 3 includes dual-frequency precision GPS for better accuracy in urban areas or mountain trails. It also has exclusive features like Backtrack, waypoint navigation, and a depth gauge for divers. The Series 11 supports all-day fitness tracking but is more focused on general health and activity rings.
Health Tracking: Both watches include ECG, blood oxygen monitoring, and temperature sensing for cycle tracking. The Ultra 3 may be preferred by athletes and divers who want rugged reliability, while the Series 11 is more than enough for casual wellness tracking.
Weight and Comfort: The Series 11 is significantly lighter, which some users may find more comfortable for daily wear or sleep tracking. The Ultra 3 is heavier but distributes weight well and feels secure on the wrist even during intense movement.
Connectivity: Both models include Bluetooth 5.3, Wi-Fi, and cellular options, but the Ultra 3 ships with cellular capability standard, which is helpful for adventurers leaving their iPhone behind.
