As Apple prepares for its hardware debut on September 9, tech analyst Mark Gurman has outlined the expected specifications for the upcoming Apple Watch Series 12 and Apple Watch Ultra 4. While avoiding a complete structural redesign or Touch ID integration, the new lineup focuses on a faster proprietary SoC, continuous heart-rate data collection, and a returning ceramic case option.
The Hardware Trajectory: S11 Silicion and Form-Factor Stasis
Under the hood, the upcoming smartwatches are poised to deliver the first meaningful architectural performance improvements in multiple years. The preceding Apple Watch Series 11 and Ultra 3 relied on the same S10 chip architecture originally introduced with the Series 10 and Ultra 2 models. Internal code discovered in developer files—referencing model numbers N237, N238, and N240—confirms that late-stage testing is underway for both Wi-Fi-only and cellular variants of the Series 12 alongside the Ultra 4.
Despite these internal hardware refreshes, exterior alterations remain minimal. Gurman indicated that neither the Series 12 nor the Ultra 4 will feature major structural design overhauls compared to their predecessors. Initial speculation regarding biometric fingerprint authentication via Touch ID has largely quieted, with analysts noting that implementing such a sensor would likely necessitate a structural redesign that Apple is saving for future product cycles. Similarly, rumors regarding health sensors embedded directly into the watch band lack substantiated proof.
Advanced Health Sensing and Software Capabilities
Beyond silicon upgrades, Apple is refining its physiological telemetry tracking. Testing on the Series 12 includes a feature allowing the native heart-rate sensor to continuously harvest and compile data throughout the day. Concurrently, Apple is restructuring its native Health and Fitness applications to surface deeper wellness metrics, mirroring the layout and data visualization popularized by fitness ecosystems like Whoop and Oura.
Meanwhile, companion software developments arriving via watchOS 27 will expand functionality across existing and upcoming devices. The upcoming software release will introduce expanded Workout Buddy features and improved fitness insights. Satellite connectivity features—including expanded Apple Maps support over satellite and multimedia messaging capabilities—will also roll out to current hardware like the Ultra 3, distinguishing network-level software upgrades from exclusive hardware milestones.
The Return of Ceramic and the Missing SE Tier
Material finishes are seeing a selective revival. Apple is testing both white and dark gray ceramic case configurations for the Series 12, marking a return of the premium material last seen on high-end configurations of the Series 3 in 2017 and Series 5. Meanwhile, the budget-friendly tier remains static; an Apple Watch SE 4 is not scheduled for release this year, leaving the spotlight entirely on the flagship Series 12 and the rugged Ultra 4.
Longer-term roadmaps suggest that while a major physical redesign is still slated for the coming years, more revolutionary biomedical additions—such as non-invasive blood sugar detection—remain in deep development with target windows extending toward 2030.
The 30-Second Verdict
- Launch Window: Expected debut on September 9.
- Performance: First major chip architecture upgrade since the S10.
- Design: Retains current case dimensions; ceramic finish returns in white and dark gray.
- Health Tracking: Continuous daily heart-rate telemetry and revamped Health app analytics.
- Omissions: No Touch ID, no band-embedded sensors, and no Apple Watch SE refresh this year.
