10 Best Smartwatch With Oximeter 2025 in the United States

The Apple Watch Series 10 is a top-tier smartwatch, particularly strong in health and fitness tracking. Its oximeter, along with an ECG app and various health monitoring features, offers comprehensive health insights. The watch's large, always-on Retina display is bright and clear, making it easy to read in different lighting conditions.

The build is durable, with water resistance up to 50 meters and IP6X dust resistance, making it suitable for various activities, including swimming. Battery life is decent, with up to 18 hours of use on a full charge and fast-charging capabilities. However, users looking for a more extended battery life might find it lacking.

The design is sleek and comfortable, with customizable bands to fit personal style. Compatibility is seamless with Apple devices, enhancing the user experience for Apple ecosystem users. The price point is on the higher side, which might be a consideration for budget-conscious buyers. While the Series 10 is ideal for those deeply integrated into the Apple ecosystem and in need of advanced health and fitness tracking, it may be less attractive to users looking for a more affordable option or those using non-Apple devices.

The AEAC Smart Watch is a solid choice for those wanting a smartwatch with good oximeter functionality and comprehensive health tracking. It monitors blood oxygen, heart rate, stress, and sleep with helpful insights, making it useful for everyday wellness awareness. The 1.32-inch AMOLED display is bright and responsive, offering plenty of watch faces and customization options, so it looks good on your wrist. Battery life is impressive, lasting up to 10 days on a quick 2-hour charge, so you won’t need to recharge often.

It supports over 110 sports modes, covering many activities including swimming, thanks to its 3ATM water resistance, though this means it’s safe for splashes and brief immersion but not for deep-water use. The watch connects via Bluetooth to both Android (6.0+) and iOS (9.0+) devices, ensuring wide compatibility. It also features clear call quality and voice assistant support, adding convenience. The GPS depends on your smartphone, so the watch itself doesn’t have built-in GPS.

Its weight and size are quite light and slim, which is great for comfort but might not suit those wanting a more rugged feel. The interface is straightforward with touchscreen controls, making it easy to use even if you’re new to smartwatches. A 5-year warranty shows confidence in durability and customer support. For those seeking a dependable, stylish smartwatch that tracks oxygen levels and many health metrics without breaking the bank, the AEAC model is worth considering.

The Fitbit Sense 2 is a robust smartwatch designed for health and fitness enthusiasts, particularly those looking for advanced features to monitor their well-being. One of its standout features is the SpO2 oximeter, which provides good accuracy in measuring blood oxygen levels. This can be particularly beneficial for users interested in tracking their respiratory health.

Battery life is impressive, lasting more than six days on a single charge, which is great for those who want to wear their watch continuously without frequent charging interruptions. The display quality is decent, with a clear interface that is easy to navigate, even for less tech-savvy users.

In terms of fitness tracking, the Sense 2 excels with built-in GPS, heart rate monitoring, and over 40 exercise modes. Features like the Daily Readiness Score and Active Zone Minutes help users stay motivated and informed about their activity levels. The smartwatch also offers comprehensive sleep tracking and stress management tools, making it a great option for anyone looking to improve their overall health and wellness.

Compatibility is a strong point as it works seamlessly with both iOS and Android devices, allowing users to receive notifications, calls, and texts. Moreover, the inclusion of Amazon Alexa and Fitbit Pay adds convenience for everyday tasks.

On the downside, while the smartwatch boasts numerous health features, some users might find the app interface a bit overwhelming initially. Additionally, while it's water-resistant up to 50 meters, care should still be taken to avoid exposure to extreme conditions. The design is generally comfortable, but its larger size may not suit everyone's taste.

The price point may be on the higher side for some, so potential buyers should consider if they’ll fully utilize its advanced features. Those interested in a comprehensive health-tracking device will likely find the investment worthwhile.
