Detailed Feature Comparisons
Design and Construction
The Apple Watch Ultra is noticeably larger and more rugged than the Series 9. Built with aerospace-grade titanium, it is designed for durability in extreme environments. The Series 9, while still well-built, uses aluminum or stainless steel and is slimmer and lighter. This makes the Series 9 more suitable for everyday wear, while the Ultra caters to users who need more resilience outdoors.
Display Quality
Both watches feature a bright Always-On Retina display with up to 2000 nits of peak brightness, making them easy to read in direct sunlight. However, the Ultra’s larger 1.92-inch screen offers more space for data and larger interface elements, which is helpful during workouts, hiking, or diving.

Durability and Water Resistance
The Ultra leads in durability with a 100-meter water resistance rating and EN13319 certification, making it suitable for recreational diving. It also includes a depth gauge and water temperature sensor. In contrast, the Series 9 is rated for 50 meters and is better suited for swimming and general fitness use.

These are especially useful for hikers and backcountry explorers.
Performance and Processor
Both watches are powered by the S9 chip with a 4-core Neural Engine, ensuring fast performance and on-device Siri support. The processor is identical, so day-to-day speed is the same. Both models also benefit from the same machine learning enhancements and power efficiency improvements.
Connectivity and Smart Features
