Galaxy Watch 5 and Watch 5 Pro hands-on: Barely-there updates (and one new design) The big theme for Samsung’s August Unpacked event this year seems to be refinement. Across the devices it’s launching today, the company is bringing minor tweaks and improvements to increasingly mature products. On last year’s Galaxy Watch 4 and Watch 4 Classic , the company ditched its own Tizen OS in favor of a version of Wear OS that it co-engineered with Google , and brought a new BioActive sensor that combined three biometric sensors in one. It also introduced a body composition scanner using bioelectrical impedance analysis (BIA) for more comprehensive health insights. Compared to last year’s model, the Galaxy Watch 5 seems a little boring. The biggest change this time is a new skin temperature sensor that isn’t going to be active at launch, while the other upgrades, like improved durability and curvature, aren’t immediately obvious either. I can’t blame Samsung for an unexciting generation of smartwatches, though, since the Galaxy Watch line is already arguably the best wearable for Android users.
