Garmin Forerunner 955 vs Withings ScanWatch 2
The Verdict
These smartwatches serve different athletic priorities. Garmin Forerunner 955 excels for runners and triathletes with built-in GPS, 42-hour GPS battery (49 with solar), NFC payments, and Garmin's specialized sports tracking ecosystem. Its 1.3-inch MIP display offers excellent outdoor visibility and 15-day smartwatch battery. Withings ScanWatch 2 focuses on medical-grade health metrics, featuring ECG, skin temperature monitoring, and SpO2 tracking alongside a distinctive hybrid analog watch face with OLED sub-display. At 30 days battery life and 39g weight, it's lighter and lasts longer in standard mode. Withings lacks GPS and sports-specific training tools, limiting its utility for serious distance athletes. Garmin costs $150 more but justifies this through dedicated sports features and solar charging. Choose Forerunner 955 if running or multisport training matters most. Pick ScanWatch 2 if comprehensive health monitoring, battery longevity, and lighter weight take priority, though you'll need a phone for GPS recording.
