Apple Watch Series 12 and watchOS 27: Upcoming Features and Specs to Look For

By ⚡ min read

Overview

While details about Apple's next-generation smartwatch lineup remain scarce, a few compelling rumors have surfaced regarding both hardware changes and software enhancements. The upcoming Apple Watch Series 12 and Apple Watch Ultra 4 are anticipated to launch this September, alongside the release of watchOS 27. Notably, a new Apple Watch SE is not expected this year, as the current model was refreshed in 2025 and typically follows a two-to-three-year update cycle.

Expected Release Timeline

Apple will preview watchOS 27 during the WWDC 2026 keynote on Monday, June 8. A developer beta is likely available immediately after the announcement, followed by a public beta in July. The final version of watchOS 27 should roll out to all compatible devices in September, coinciding with the new Apple Watch models.

Touch ID on Apple Watch

One of the most intriguing rumors involves the potential addition of Touch ID to the Apple Watch Series 12 and Apple Watch Ultra 4. Internal Apple software code that leaked last year contained references to Touch ID functionality. If implemented, the fingerprint sensor would likely be integrated into the side button, allowing users to unlock their watch without entering a passcode.

Despite these code references, there is no guarantee that Apple will proceed with this feature. Reputable analysts such as Bloomberg's Mark Gurman and Ming-Chi Kuo have not mentioned Touch ID for the upcoming models. As with any pre-release rumor, plans could change or be shelved entirely.

New Processor After a One-Year Hiatus

The Apple Watch Series 11, Apple Watch Ultra 3, and Apple Watch SE 3 all featured the same S10 chip as their predecessors. However, leaked code indicates that the Series 12 and Ultra 4 will receive a new processor. Whether it will be branded as S11 or S12 remains unclear, but performance improvements are expected. A faster chip could enable smoother animations, quicker app launches, and better power efficiency.

New Watch Faces in watchOS 27

watchOS 27 is rumored to introduce fresh watch faces, including a version of the popular "Modular Ultra" face that is currently exclusive to the Apple Watch Ultra. This would bring the highly customizable, data-rich design to a wider range of users.

Enhanced Apple Intelligence Features

Currently, watchOS 26 offers several Apple Intelligence features when paired with an iPhone 15 Pro or newer, including:

Workout Buddy – an AI-powered workout companion.
Live Translation in Messages – real‑time language translation.
Notification Summaries – concise summaries of alerts.

When Apple announced the dates for WWDC 2026, the company promised to unveil "AI advancements" across its platforms. It's reasonable to expect that watchOS 27 will include additional Apple Intelligence features—likely powered by the connected iPhone, as the Watch itself may not have sufficient on‑device processing capabilities.

New Satellite Capabilities

The Apple Watch Ultra 3 already supports satellite connectivity for Emergency SOS, Find My, and Messages via satellite without needing an iPhone. According to reports, iOS 27 will introduce up to five new satellite features, and at least two of them are expected to extend to watchOS 27:

Apple Maps via satellite – navigate with turn‑by‑turn directions even when offline.
Photos support for Messages via satellite – send and receive images over satellite connections.

In a related development, Amazon announced plans to acquire Globalstar, the satellite company that powers Apple's satellite services on iPhone 14 and newer, as well as the Apple Watch Ultra 3. This acquisition could potentially affect future satellite integration, though Apple has long‑term agreements in place.

Conclusion

While much remains uncertain, the Apple Watch Series 12 and watchOS 27 are shaping up to bring meaningful updates. From a potential Touch ID sensor and upgraded processor to new watch faces, advanced AI capabilities, and expanded satellite services, the next generation of Apple's wearable ecosystem promises to refine both hardware and software. As always, these rumors should be taken with a grain of salt until Apple makes official announcements at WWDC and the September event.
