Galaxy Watch 8 Classic - SCIENTIFIC Review (Better Than Normal Version?)
These notes were generated by AI and may contain inaccuracies.
The Galaxy Watch 8 Classic is arguably the best looking Galaxy Watch from the newest 8 series. The Galaxy Watch 8 and Galaxy Watch Ultra 2 were released at the same time. It looks the best, but does it perform the best? Tests cover heart rate tracking during exercise, sleep accuracy, and GPS/location tracking (e.g., bike speed, running pace).
Rob, a post-doctoral scientist specializing in biological data analysis, uses data to analyze the Galaxy Watch 8 Classic performance. Video delayed due to Samsung Health data export issues, but new data collected with interesting results.
Easiest exercise for devices due to minimal movement. Galaxy Watch 8 Classic shows good agreement with reference device; high correlation of 0.96 (0.95+ is good enough). Dots close to blue line in scatter plot.
Individual bike rides (intervals):
- First interval HR increase, long break, then 2nd-5th intervals: Watch in red follows reference in blue-green very well.
- Other rides: minor details missed, almost perfect; one longer ride started late, performed well; minor issues with slightly too high HR twice.
Overview plot: further top-right is better. Galaxy Watch 8 Classic (red) at 0.96 correlation, middle but good enough.
Zoomed (0.95+): Similar to Galaxy Watch 8, Galaxy Watch 7 (same sensor). Bug shows Classic twice.
Top (0.98+): Huawei devices, Pixel Watch (Android), Pixel Watch 3, Helio strap, Apple Watches better. Still recommendable for indoor cycling.
