2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerApple Watch Ultra 2 vs Garmin Instinct 2X Solar
If you're after the brightest display, the Apple Watch Ultra 2 is the flagship option with a stunning 3,000 nits. But if battery life is your priority, Garmin Instinct 2X Solar can stretch up to 40 days, thanks to solar charging. The decision boils down to whether you value display quality or unmatched battery longevity. After testing both, the Apple Watch Ultra 2's standard battery lasts 36 hours, which is impressive for a smartwatch, but the Garmin's potential for unlimited battery life in smartwatch mode means fewer charging interruptions. If you're someone who spends long days outdoors, this could mean the difference between staying connected or not. You'll love the Garmin for extended adventures, but know that it lacks the vivid color display of the Apple Watch Ultra 2, which is perfect for everyday use and notifications.
