2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerSamsung Galaxy Watch 7 vs Google Pixel Watch 3 (45mm)
The Samsung Galaxy Watch 7 is the premium option here, boasting a lightning-fast 3nm Exynos W1000 chip that literally crushes performance. In real-world use, this means snappier app launches and smoother interactions compared to the Google Pixel Watch 3's performance. However, both require daily charging—the Galaxy Watch lasts about one day while the Pixel Watch can go up to 24 hours with Always-On Display enabled. What matters most here is the display: the Pixel Watch 3 features a 1.4-inch screen at 2000 nits, making it brighter than the Galaxy Watch’s 1.2-inch display. If you’re into fitness tracking, the Galaxy Watch 7’s dual-frequency GPS offers superior accuracy in urban areas, while the Pixel Watch provides advanced running metrics without needing extra gear. Both are solid options, but each has unique strengths.
