Amazfit T-Rex 2 vs Withings ScanWatch

The Verdict

Both watches excel in battery life and health monitoring, but serve different priorities. The Amazfit T-Rex 2 features a larger 47mm AMOLED display with 454x454 resolution, built-in GPS for standalone tracking, and exceptional 24-day battery life, making it ideal for outdoor enthusiasts and fitness trackers. At 66.5g it's noticeably heavier with polymer construction, though it achieves superior water resistance at 10ATM. The Withings ScanWatch takes a refined hybrid approach, pairing an elegant analog dial with a small PMOLED digital display, weighing just 58g in stainless steel with sapphire crystal. Its standout feature is ECG capability for heart rhythm monitoring, something the T-Rex 2 lacks. The ScanWatch compensates for missing GPS by offering WiFi connectivity and delivers impressive 30-day battery endurance. At $229 versus $299, the T-Rex 2 provides better value for active users needing GPS and a larger screen. Choose the T-Rex 2 if you prioritize outdoor activities, training metrics, and screen real estate. Select the ScanWatch if you prefer a traditional watch aesthetic, need ECG monitoring for health insights, and value lighter weight with premium materials. The T-Rex 2 edges ahead for sports-focused users, while ScanWatch wins for medical-grade monitoring and daily elegance.
