Available for pre-order starting July 17, 2025, and set for release in early August, these devices promise users an unprecedented blend of style and functionality.

TM Roh, President of Samsung Electronics and head of MX Division, stated, "Through innovative technology, we aim to support people around the world in living healthier and more fulfilling lives. The Samsung Galaxy Watch8 Series embodies a sophisticated design combined with advanced sensor technology and an intuitive AI experience, bolstering users’ health and enhancing their lifestyles. This series aims to make it easier than ever for users to maintain a better daily routine."

Key Features of Samsung Galaxy Watch8 and Watch8 Classic

The Samsung Galaxy Watch8 series introduces a significant evolution in both design and functionality, delivering outstanding comfort coupled with top-tier performance, making it an ideal companion for daily wellness. The unique Cushion Design debuted in the Galaxy Watch Ultra has been integrated across the lineup, ensuring a sleek aesthetic without compromising durability.

To achieve the thinnest profile in the series’ history, Samsung re-evaluated the internal structures, improving the implementation efficiency of components by about 30%. This innovation resulted in a dramatic reduction in thickness of approximately 11% compared to previous models, with the newly added Dynamic Lug System fitting naturally around the wrist during movement, ensuring better comfort and stability, leading to enhanced health tracking accuracy.

In addition to a streamlined design, the display on the Galaxy Watch8 series has seen a brightness increase of about 50%, achieving a stunning 3,000 nits, making it easily viewable under direct sunlight. Battery performance has also been upgraded, supporting an active lifestyle more reliably than ever. The dual GPS feature allows for more precise location tracking, and Samsung’s powerful 3nm processor ensures faster processing speeds alongside optimized power efficiency. The high-performance BioActive Sensor delivers comprehensive and accurate health insights, facilitating a multi-faceted approach to user health management.

Personal Health Coaching Features

Recognizing the importance of sleep as a key indicator of health, the Galaxy Watch8 series focuses on sleep quality. By monitoring sleep duration and stages, it provides insights and personalized coaching to improve sleep habits. The Samsung Health app now features new health management functions, offering real-time feedback and motivation for sleep, nutrition, and workout information to encourage healthier habits.

This series marks another first with the introduction of a vascular load metric, monitoring stress levels on the vascular system during sleep. Alerts are provided when stress levels are elevated, guiding users on how to manage their well-being. The AI-driven Energy Score combines physical and mental energy metrics for a clear overview of daily energy levels, promoting a healthier lifestyle.

Enhanced User Experience with Wear OS 6

Developed in collaboration with Google, the Galaxy Watch8 series operates on Wear OS 6 and features Google’s AI agent, Gemini. With natural voice commands, users can control various apps hands-free, enhancing the overall interaction. For instance, users can simply instruct the watch to start tracking a workout or send messages, making health monitoring straightforward and intuitive.

The newly implemented One UI 8 Watch enhances the user interface, allowing for optimal viewing of health metrics, weather updates, and schedules in one glance. Notifications and vital activities are more accessible, ensuring that essential information is always at the forefront of the user experience.

A Design for Every Lifestyle

Available in two sizes—44mm and 40mm—and colors such as Graphite and Silver, the Samsung Galaxy Watch8 offers a refined minimalist design that integrates seamlessly into everyday life. In contrast, the Galaxy Watch8 Classic, featuring a rotating bezel and premium functionality, projects a sophisticated image and is available in a 46mm format. Each model comes with stylish bands that can be tailored to individual preferences.

The Ultimate Outdoor Companion: Galaxy Watch Ultra (2025)

The Samsung Galaxy Watch Ultra is designed specifically for outdoor enthusiasts, boasting superior durability and performance. The inclusion of a new Titanium Blue color adds not only aesthetic appeal but aligns with a spirit of resilience. All color options feature a titanium finish, promising the longest battery life in the Galaxy Watch series yet.

Equipped with the latest One UI 8, enhanced ease of use is promised, alongside a storage expansion to 64GB, ensuring that users can store important data safely. The devices support FeliCa, enabling contactless transactions seamlessly with just a wrist gesture, making them ideal companions for individuals who are always on the move.
