CUPERTINO, Calif. – Apple unveils a transformative update to its wearable technology with watchOS 26, marking a pivotal shift for the Apple Watch Series 9, Series 10, and Ultra 2 models.

Breaking: Apple Watch Embraces Full ARM64 Architecture

At first glance, watchOS 26 may seem like a minor update compared to the sweeping changes in iOS, iPadOS, and macOS. However, Apple has made a significant under-the-hood change by transitioning its latest Apple Watch models to a full ARM64 architecture, as reported by MacRumors.

Immediate Impact

The move to ARM64 architecture enhances the performance and compatibility of the Apple Watch, providing 64-bit pointers and access to broader memory ranges. This upgrade opens the door for more complex and computationally intensive applications on the wearable device.

Key Details Emerge

In Apple’s watchOS 26 video for developers, the company detailed the architectural transition from arm64_32 to full arm64. This move is expected to pave the way for more advanced features and applications on the Apple Watch.

Workout Buddy: A Step Towards AI Integration

One of the standout features of watchOS 26 is the introduction of Workout Buddy, which utilizes “Apple Intelligence” from the iPhone to provide personalized encouragement based on workout data and fitness history.

Technical Requirements

  • Requires iPhone 15 Pro or newer
  • Relies on text-to-speech models from Apple Fitness+ trainers

This feature, while promising, still relies on the iPhone, hinting at future developments where the Apple Watch could operate more independently.

Industry Response

While some industry experts had anticipated a stronger AI push, Apple has only introduced limited AI features in this update. The company’s focus on architectural improvements suggests a long-term strategy for more robust capabilities in future models.

By the Numbers

  • Apple Watch Series 9, Series 10, and Ultra 2 are now on full ARM64
  • 64-bit architecture allows for broader memory access
  • Potential for more complex applications and features

What Comes Next

The architectural overhaul in watchOS 26 could be a precursor to more powerful chips in future Apple Watch models, such as the anticipated Series 11 and Ultra 3. These advancements may enable features like Workout Buddy to function independently of the iPhone.

As Apple continues to refine its wearable technology, the implications for AI integration and performance enhancements remain a significant area of interest for both consumers and industry analysts.

Background Context

The transition to ARM64 architecture is part of Apple’s broader strategy to unify its hardware and software capabilities across devices. This alignment is expected to foster a more seamless and powerful user experience.

Apple’s commitment to innovation in its wearable technology underscores the company’s dedication to maintaining its leadership in the smartwatch market.

As the tech giant moves forward, the developments in watchOS 26 are likely to influence future product iterations and set the stage for new advancements in wearable computing.
