Withings ScanWatch 2 vs Garmin Vivosmart 5

For professionals and mechanical-watch lovers who refuse to wear a glowing digital computer with a dress shirt, the Withings ScanWatch 2 conceals FDA-cleared single-lead ECG, SpO2, and 24/7 TempTech baseline temperature tracking beneath a classic Swiss-styled analog dial with anti-reflective sapphire glass. Its 30-day battery life per charge is phenomenal, though its tiny 0.63-inch grayscale PMOLED sub-dial is meant for quick health checks rather than workout intervals.

The Garmin Vivosmart 5 is the best fitness band for shoppers who want Garmin's completely subscription-free Body Battery energy monitoring, sleep score, all-day stress tracking, and Morning Report in a slim 26.5-gram strap. It relies on your phone for connected GPS and uses a utilitarian monochrome OLED screen, but never locks your historical health data behind a monthly paywall.
