The Verdict

Amazfit GTS 4 delivers a modern smartwatch experience with its vibrant 390x450 AMOLED display and snappy Zepp OS 2.0 performance, making it ideal for fitness enthusiasts who want quick app interactions and customizable watch faces. At 27 grams, it's significantly lighter and more comfortable for all-day wear compared to the ScanWatch's 58-gram stainless steel design. However, the Withings ScanWatch positions itself as a hybrid health device rather than a traditional smartwatch, featuring clinical-grade ECG capabilities that the GTS 4 lacks, plus a remarkable 30-day battery life versus the GTS 4's 8 days. The ScanWatch's analog dial with complementary PMOLED display appeals to those preferring traditional watch aesthetics, though its lack of GPS limits workout tracking versatility. Choose the Amazfit GTS 4 if you prioritize vibrant display quality, lighter weight, extensive app ecosystem, and frequent charging isn't a concern. Select the Withings ScanWatch if medical-grade health monitoring and exceptional battery endurance matter more than feature richness, accepting the heavier build and display limitations as worthwhile trade-offs.
