Ray versus Withings ScanWatch 2
An analog watch with ECG and a month of battery, compared with Ray.
Withings ScanWatch 2 is a hybrid watch from $349.95: real watch hands, a small display and spot checks like ECG and blood oxygen. It lasts up to 35 days per charge, which is unusually long, and Withings+ is optional. Ray is far lighter, has no display and powers itself from light.
The short answer
Choose ScanWatch 2 if you want an analog watch with ECG and long battery life. Choose Ray if you want a much lighter, display-free tracker you never charge.
