2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerSamsung Galaxy Watch Ultra vs Samsung Galaxy Watch 7
Get the Samsung Galaxy Watch Ultra unless you need a similar-weight option. The numbers: 100 hours of battery life vs just 1 day, and a rugged 47mm titanium build that crushes the 40mm Armor Aluminum Watch 7. In real-world use, the Ultra’s 3000 nits display shines brighter outdoors, making it a no-brainer for outdoor activities. However, if you're looking for a more lightweight design, the Galaxy Watch 7's 1.19oz is more comfortable for daily wear, especially for smaller wrists.
⚖️ Weight: 2.13 oz vs 1.19 oz🔋 Battery: 100h vs 1 day📱 Display: 3000 nits vs 2000 nits
