Top 2025 Smartwatches Capable of Monitoring Blood Oxygen Saturation Levels
Blood oxygen, or SpO2, is a crucial health metric that indicates your respiration and breathing health. Many smartwatches can monitor this, but which one does it best? If you're an Apple user in the U.S., you'll have to look beyond the Apple Watch due to its ongoing legal issues with Masimo.
My top pick is the Garmin Venu 3. It offers up to 14 days of battery life, constant SpO2 readings, and a variety of health features. It's stylish, durable, and jam-packed with features that make it a fantastic overall choice.
If the Venu 3 doesn't float your boat, I've rounded up a few more of the best smartwatches with blood oxygen monitoring. These handpicked devices cater to various budgets and needs, ensuring there's something for everyone.
