2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerSamsung Galaxy Watch 7 vs Apple Watch Ultra 3
If you're torn between the Samsung Galaxy Watch 7 and the Apple Watch Ultra 3, the choice is clear: the Apple Watch Ultra 3 shines with its rugged build and class-leading 3,000-nit display. In real-world use, that means visibility in bright sunlight is unbeatable—perfect for outdoor enthusiasts. The Samsung Galaxy Watch 7 offers a premium experience with its super-fast 3nm Exynos W1000 chip. However, it only manages about 1 day of battery life, which can be a hassle if you're on the go and need something that lasts longer than a single day. It’s worth considering what you value more in a watch: performance or durability and battery life.
