Here are some essential specs to consider when picking a smartwatch with an oximeter.
Oximeter AccuracyAn oximeter measures the oxygen saturation in your blood, which is crucial for monitoring your overall health. Accuracy is important because it ensures that the readings you get are reliable. Look for smartwatches that have been validated for medical accuracy or have good reviews regarding their oximeter function. If you have specific health concerns, a more accurate oximeter might be necessary.

These features provide a more comprehensive view of your health. If you are looking to monitor multiple aspects of your health, choose a smartwatch that offers a wide range of health tracking features.
DurabilityDurability refers to how well the smartwatch can withstand daily wear and tear, including exposure to water and dust. This is important for ensuring the longevity of your device. Look for smartwatches with water resistance and robust build quality. If you lead an active lifestyle or plan to use the smartwatch in various environments, a more durable model will be beneficial.
