Apple’s September 2025 event is just weeks away, and anticipation is high for the Apple Watch Series 11. While early leaks suggest the overall design will remain similar to previous models, both hardware and software are expected to receive meaningful updates. With the introduction of watchOS 26 and potential new health features, the Series 11 could be a more capable and connected wearable than ever before.

Below, we break down the five most notable rumored upgrades.
1. S11 Processor and 5G RedCap Connectivity
Each Apple Watch generation has introduced a faster chip, and the Series 11 is expected to follow suit with the S11 processor. This chip should improve both performance and power efficiency, potentially delivering longer battery life and smoother navigation.
In addition, reports indicate Apple may move to a MediaTek modem with 5G RedCap support. This would mark the first time the Apple Watch supports a form of 5G connectivity, replacing LTE in select models. 5G RedCap (Reduced Capability) is designed for wearables, offering faster speeds with lower power draw.
For those considering the rugged Apple Watch Ultra 3, leaks also hint at satellite connectivity for sending messages in areas without cellular coverage.
2. watchOS 26 and the Liquid Glass Interface
The watchOS 26 update will debut alongside the Series 11, introducing a fresh design language and new AI-powered tools.
Key additions include:
-
Liquid Glass UI – A translucent, frosted-glass appearance across apps, widgets, and notifications, giving the interface a cleaner and more modern look.
-
Workout Buddy – An AI-driven personal trainer powered by Apple Intelligence. It provides real-time workout feedback, motivation, and tips, using voice models trained on actual Apple Fitness+ coaches.
-
Wrist Flick Gestures – Quickly dismiss notifications or return to the home screen with a simple flick of the wrist.
-
Notes App – Syncs with your iPhone or iPad so you can view all your notes on your watch. You can also create new notes via dictation, drawing, or the on-screen keyboard, though editing existing notes is still unavailable.
-
Live Translation – Translates messages in real time directly from your wrist.
-
Improved Smart Stack – More context-aware widgets, plus a redesigned Workout app interface for quicker access to essential features.
3. Sleep Score Tracking
Apple’s sleep tracking is expected to get a significant upgrade with the introduction of a Sleep Score feature. This would combine metrics like sleep duration, stages, and interruptions into a single, easy-to-read score.
Unlike basic trackers, Apple could integrate additional health data-such as heart rate variability or oxygen saturation-for a more comprehensive sleep assessment. This builds on Apple’s history of health features that meet high accuracy standards.
4. Blood Pressure Trend Alerts
While not confirmed for the standard Series 11, the Apple Watch Ultra 3 is rumored to be the first Apple wearable to support blood pressure trend detection. Instead of providing exact systolic and diastolic numbers like a traditional cuff, the watch would alert users when their readings are trending toward hypertension. This information could be shared with healthcare providers for further testing.
Even if it launches only on the Ultra 3 initially, future software updates could bring the feature to other models.
5. A Unified, Modern Design
Beyond the technical upgrades, the Series 11 will benefit from the visual consistency Apple is pushing across all its platforms. The Liquid Glass interface is part of a broader UI refresh coming to iOS, iPadOS, macOS, and watchOS, creating a more seamless look and feel for users in the Apple ecosystem.
