The Series 12 is rumoured to introduce sleep apnea expansion, a new chip, and potentially blood glucose sensing — launching alongside iPhone 18.
| Model | Battery | GPS | Key Sensors | Best For |
|---|---|---|---|---|
| Series 11 (42mm) | ~24h (36h low power) | Yes, L1+L5 dual-freq | ECG, SpO2, hypertension, skin temp | Compact daily health tracking. |
| Series 11 (46mm) | ~24h (36h low power) | Yes, L1+L5 dual-freq | ECG, SpO2, hypertension, skin temp | Larger screen and slightly longer battery. |
The Apple Watch Series 11, released September 2025, is Apple's thinnest Watch ever and introduces hypertension detection — a clinically significant health milestone that joins its existing suite of ECG, SpO2, skin temperature, and HRV monitoring. Starting at $399, it's the benchmark for smartwatch health features in 2025–2026.
The Series 11 is the first mainstream smartwatch to offer FDA-cleared hypertension (high blood pressure) detection — a feature that could flag silent health risks.
At 9.7mm, the Series 11 is significantly slimmer than previous models — noticeably lighter on the wrist for all-day and sleep tracking.
On-demand ECG, continuous blood oxygen monitoring, and sleep apnea detection (FDA-cleared) make this one of the most medically relevant consumer wearables available.
iPhone users who want the most capable smartwatch health experience available. Ideal for anyone who values medical-grade monitoring (ECG, blood pressure, SpO2), a premium always-on display, and the best Apple Watch workout tracking. If health is your priority, this is the one to get.
Series 12 is expected in fall 2026. If you need a watch now and want hypertension + ECG features, the Series 11 is excellent. If you can wait 6 months, you'll either get the new model or a meaningfully discounted Series 11.
The key addition is hypertension detection. The Series 11 is also slightly thinner and includes a new S11 chip. The Series 10 is still a capable watch and may be available at a discount.
It detects hypertension (a pattern of elevated blood pressure readings) rather than measuring exact mmHg values. It is FDA-cleared for this notification feature, not as a blood pressure monitor.
Yes — Apple Watch Series 11 can detect signs of sleep apnea and notifies you if it observes moderate to severe breathing disturbances. The feature requires watchOS 11 and is FDA-cleared in eligible regions.
The Ultra 3 adds a titanium case, dual-frequency GPS, 60h battery, a physical Action button, underwater diving modes, and satellite emergency SOS. The Series 11 covers 95% of use cases for $400 less.
