Detailed Feature Comparisons
Design and Construction
Both watches have a similar shape and size, but the Series 8 includes a more durable crack-resistant front crystal. This makes it better suited for rugged or active use. Series 6 still looks premium, though its front is slightly more prone to scratches depending on the case material.
Display Quality
The display technology is nearly identical between the two. Both support Always-On mode and reach up to 1000 nits of brightness. This means they remain visible in direct sunlight. However, Series 8 includes better crack resistance, making the screen slightly more durable.
Performance and Speed
The Series 8 runs on the newer S8 chip, while the Series 6 uses the S6. Real-world usage differences are minimal, but the S8 may feel snappier during software updates or when launching apps, especially with future watchOS versions.
Health and Safety Features
This is where Series 8 pulls ahead. It includes a body temperature sensor for cycle tracking and crash detection that can alert emergency services in a car accident. Series 6 still offers core health tools like ECG and blood oxygen, but lacks the newer additions that focus on safety and women’s health.
Battery and Charging
Battery life is similar at 18 hours, but the Series 8 supports fast charging. This is helpful if you wear your watch for sleep tracking and need a quick boost in the morning.
Fitness and Activity Tracking
Both watches support comprehensive fitness tracking. You get all the standard activity rings, workout modes, and sleep tracking. However, Series 8’s new sensors improve accuracy slightly, especially when used with third-party health apps.
Software Compatibility
Both devices support the latest watchOS updates. Series 8 launched with watchOS 9 and runs watchOS 10 smoothly. Series 6 started with watchOS 7 and is also compatible with watchOS 10, although it may reach its software limit sooner.
