A standout feature across the Apple Watch Series 11, Ultra 3, and select older models is the introduction of hypertension alerts. Using the optical heart sensor, these watches analyze blood vessel responses to heartbeats, detecting patterns of chronic high blood pressure over 30-day periods. Apple estimates this feature could notify over 1 million people with undiagnosed hypertension in its first year. Unlike traditional blood pressure monitors, it doesn’t provide specific systolic or diastolic readings but focuses on trends, encouraging users to consult healthcare professionals for further evaluation. This capability, also available on Series 9 and 10, marks a significant step in preventative health technology.
Sleep Score Enhances Wellness Tracking
Sleep tracking gets a major upgrade with the new Sleep Score feature, available on all three 2025 models with watchOS 26. This tool evaluates sleep duration, bedtime consistency, wake-up frequency, and time spent in each sleep stage to provide a comprehensive assessment of sleep quality. Users receive actionable insights to improve rest, such as adjusting bedtime routines or minimizing disruptions. The feature integrates with the Health app on iPhone, offering detailed charts and trend analysis for a holistic view of wellness.
Apple Watch Ultra 3: Built for Adventure
The Apple Watch Ultra 3 is designed for rugged use, with a larger display and slimmer bezels for improved readability during outdoor activities. It boasts up to 42 hours of battery life under normal use and 72 hours in low-power mode, making it ideal for marathons or multi-day hikes. A key addition is satellite connectivity, allowing users to send emergency messages without cellular or Wi-Fi coverage. The Ultra 3 also introduces 5G RedCap support, offering faster connectivity than previous LTE models. Its dual-precision GPS ensures accurate route tracking, even in dense urban environments.
Apple Watch Series 11: Everyday Performance
The Series 11 maintains Apple’s focus on incremental improvements, featuring the new S11 chip for enhanced efficiency and performance. It supports 5G RedCap connectivity, a first for the Series line, ensuring faster data speeds for users on the go. Available in 42mm and 46mm sizes, starting at $399, the Series 11 also offers a premium Titanium model at $699 with cellular included. The Always-On display and intuitive gestures like double tap and wrist flick make interactions seamless, whether answering calls or dismissing notifications.
Apple Watch SE 3: Affordable Innovation
The Apple Watch SE 3, priced at $249, brings premium features to a budget-friendly package. It adopts the S11 chip, matching the performance of its pricier siblings, and introduces an Always-On display for the first time in the SE line. Available in 41mm and 45mm sizes, it features a redesigned plastic casing for durability and affordability. While it lacks advanced health sensors like ECG or blood oxygen monitoring, it supports core features like heart rate tracking and sleep apnea detection, making it a compelling option for cost-conscious buyers.
AI-Powered Features and Software Updates
All three models run watchOS 26, which introduces AI-driven features like Workout Buddy, available on the Ultra 3 and Series 11. This tool analyzes workout data—heart rate, pace, distance, and fitness milestones—to deliver personalized, spoken motivation during exercise sessions. It requires an Apple Intelligence-enabled iPhone and Bluetooth headphones, with initial support in English. Other updates include Live Translation in Messages, supporting languages like Spanish, Japanese, and Mandarin, and improved Smart Replies for faster communication.
