Best Smartwatches of 2024

That’s why CR’s ratings take into account a watch’s health-related capabilities. These range from overall wellness metrics like sleep tracking and stress monitoring to cardiac metrics. For some watches, they can include both basic measurements like heart-rate monitoring, and also electrocardiogram (ECG) readings and performance indicators like heart-rate variability. Any health-related data you get from your watch can be used to begin a discussion with your doctor.

We also test watches on factors such as step count accuracy, ease of use, versatility, waterproofness of the case, and durability of the display.
