Best for: People who want ECG and overnight health tracking in a watch that looks like a regular analog piece.

Withings ScanWatch Light
~$250
Withings' entry hybrid keeps the analog dial, 35-day battery and 24/7 heart-rate tracking with high and low heart-rate alerts, but drops ScanWatch 2's ECG, SpO2, temperature sensing and overnight HRV.
Best for: Smaller wrists and buyers who want sleep and heart-rate tracking in a slim analog watch, without paying for ECG.
