The Ultra 2 also has the longest battery life at a claimed 36 hours, or 72 hours in low power mode, while the Series 9 and SE offer 18 hours of battery life each.
In terms of fitness features, all three models offer similar activity tracking through the Activity app and support the Workout app. The Series 9 and Ultra 2 are capable of on-board processing of Siri requests, while the SE does not have this capability.
The Apple Watch SE starts at $250, the Series 9 at $399, and the Ultra 2 at $799. Each model offers various connectivity and case size options, and all are compatible with Apple’s Fitness+ subscription for $10 per month.
