2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerSamsung Galaxy Watch 7 vs Garmin Instinct 2X Solar
The Samsung Galaxy Watch 7 is the premium option here, boasting a seriously impressive 3nm Exynos W1000 chip for lightning-fast performance. However, if battery life is your primary concern, the Garmin Instinct 2X Solar shines with up to 40 days of use, and potentially unlimited battery when solar charging. In real-world testing, I found that the Galaxy Watch 7's advanced health metrics offer plenty of insight, but it requires daily charging. Meanwhile, the Garmin's rugged design and built-in LED flashlight make it the go-to for outdoor adventures, even if the monochrome screen lacks the vibrant detail of AMOLED displays. That said, the deciding factor often comes down to whether you prioritize features or longevity in a smartwatch.
