This sleeker design, combined with a “cushion shape” and dynamic lug system for watch bands (borrowed from the Galaxy Watch Ultra), enhances comfort and ensures the sensors stay closer to the wrist for more accurate readings.
The Super AMOLED display remains a visual highlight, matching the Watch 7 in size (1.34-inch/1.47-inch) and resolution. However, the Watch 8’s screen gets significantly brighter, reaching an astounding 3,000 nits (up from 2,000 nits). This ensures exceptional visibility even in direct sunlight, a crucial improvement for outdoor activities.
Durability and Classic Model Differences
The standard Galaxy Watch 8 is available in 40mm and 44mm sizes, with color options including silver and graphite. It uses various band types like rubber sport straps and fabric bands. For those who prefer a more traditional aesthetic, the Galaxy Watch 8 Classic launches alongside the base model. The Classic features a physically rotating bezel, a beloved design element offering intuitive interface navigation. It comes in a larger 46mm size, a more substantial and bulkier form factor that might appeal to users with larger wrists. The Classic also boasts a stainless steel body and doubles the internal storage to 64GB, positioning it as a premium option.
Performance & User Experience
The Samsung Galaxy Watch 8 delivers a consistently smooth and responsive user experience, powered by a five-core Exynos W1000 processor with 2GB of RAM and 32GB of internal storage. It runs on Wear OS 6, Google’s latest smartwatch software, overlaid with Samsung’s One UI 8 interface, offering seamless navigation and quick app access.
Seamless Setup and Intuitive Controls
Setting up the Galaxy Watch 8 is remarkably straightforward, particularly for existing Samsung phone users.
