The Galaxy Watch 8 has now launched, so this Samsung Galaxy Watch 8 vs Galaxy Watch 7 comparison uses confirmed facts, not rumours. Samsung unveiled the Watch 8 series in July 2025 with a new squircle design. Consequently, Watch 7 owners face a clearer upgrade question. Furthermore, one rumoured feature never arrived.
Key Takeaways
- The Watch 8 launched in July 2025 with a squircle case design.
- Its display reaches 3,000 nits, up from 2,000 nits on Watch 7.
- The rumoured blood glucose feature did NOT launch on Watch 8.
- New health tools include Antioxidant Index and Vascular Load.
Design: The Squircle Change Is Real
Samsung moved from Watch 7’s round case to a squircle cushion design. The Watch 8 is also slimmer, at about 8.6mm thick. It comes in 40mm and 44mm sizes with a circular Super AMOLED display. Therefore, it looks noticeably different on the wrist. However, taste still decides whether different means better.
Display and Performance: Brighter, Same Chip Family
The Watch 8 display peaks at 3,000 nits, beating Watch 7’s 2,000 nits outdoors. Both generations use Samsung’s 3nm Exynos W1000 processor family. Consequently, everyday speed feels similar between them. This Galaxy Watch 8 first-look review details the launch specifications and design changes. The Watch 8 also ships with newer Wear OS and One UI Watch software.
Health Features: New Sensors, No Glucose
Pre-launch rumours promised non-invasive blood glucose monitoring. That feature did not arrive, so ignore any guide still promising it. Instead, Samsung added an Antioxidant Index and Vascular Load tracking. Both watches still cover heart rate, ECG, blood oxygen, and sleep. Therefore, health remains an evolution, not a revolution.
Should Galaxy Watch 7 Owners Upgrade?
Upgrade if you want the brighter screen and slimmer squircle design. Additionally, upgrade if the new health metrics genuinely interest you. However, Watch 7 owners lose little by waiting another generation. New buyers, meanwhile, should compare street prices carefully. A discounted Watch 7 can be the smarter value buy.
In short, the Watch 8 refines design and brightness meaningfully. It does not, however, make the Watch 7 obsolete.
