Apple Watch Series 11, SE 3, and Ultra 3 Go on Sale September 19

The Apple Watch Series 11 became the first mainstream smartwatch to alert users to signs of chronic high blood pressure when it went on sale September 19, 2025. The condition, according to the World Health Organization, is responsible for approximately 10.8 million preventable deaths annually.

Seven months after launch, the pricing landscape has shifted considerably. Amazon now sells the Series 11 (GPS, 42mm) for $329, down from Apple's $399 MSRP and near its all-time low. The Ultra 3, which debuted at $799, has received its first major discount of 2026 at Amazon: $699.99 on select Natural and Black models, a $99 reduction. The entry-level SE 3, priced at $249, dipped as low as $199 during Black Friday 2025.

The Series 11 is Apple's thinnest Apple Watch ever. Its hypertension notification system uses an optical sensor to analyze how blood vessels respond to heartbeats over a 30-day calibration period, then surfaces an alert if it detects potential hypertension; FDA clearance for the feature was still pending at launch. The capability is exclusive to the Series 11 and Ultra 3, and is not available to users under 22, those already diagnosed with hypertension, or pregnant persons. Battery life reaches up to 24 hours in normal use, with a 15-minute fast charge delivering up to 8 hours. Aluminum models now feature Ion-X front glass with a ceramic coating offering twice the scratch resistance of the Series 10.

Beyond hypertension, the Series 11 adds a daily Sleep Score on a 0-to-100 scale, factoring in sleep duration, bedtime consistency, wake frequency, and time in each sleep stage. Cellular models support 5G. Case options include 42mm and 46mm, with aluminum in Jet Black, Silver, Rose Gold, and Space Gray, and titanium in Natural, Gold, and Slate.

The SE 3 makes the strongest value case of the three. It runs on the S10 chip, the same processor found in the $799 Ultra 3, despite a $249 price tag. It is the first SE model to feature an Always-On Display, and it adds double-tap and wrist-flick gesture controls, on-device Siri with health data access, Voice Isolation for phone calls, faster charging, and 5G on cellular models. Sleep apnea notifications and wrist temperature sensing are included; hypertension detection is not. The SE 3 arrived three years after the SE 2, released in 2022, a longer gap than any previous SE generation.

At $799, the Ultra 3 targets serious athletes and outdoor users with a titanium case and up to 72 hours of battery life in Low Power Mode. Hypertension detection is included alongside the Series 11. Both models require iPhone 11 or later and iOS 26. The Amazon discount to $699.99 marks the first meaningful price movement on the Ultra 3 since its September 2025 debut.

Apple holds approximately 23 to 30 percent of the global smartwatch market, more than any other brand, and has publicly stated it sells more Apple Watches than the entire Swiss watch industry combined. Counterpoint Research reported Apple grew smartwatch shipments 18 percent year-over-year in the most recent quarter, while Samsung fell 18 percent over the same period. The global smartwatch market is valued at approximately $35.29 billion and projected to reach $91.96 billion by 2035.

Apple also offers trade-in credits of $30 to $295 toward a new Series 11. For buyers considering the SE 2, which remains available at some retailers, the SE 3 costs only roughly $40 more and represents a substantial generational upgrade.

The Apple Watch Series 12 is expected in September 2026 alongside the iPhone 18, with early speculation pointing to a new chip and potentially blood glucose sensing.
