5 Smartwatches with Blood Oxygen Monitoring Features.

The Apple Watch is popular for its blood oxygen (SpO2) monitoring feature, but now various other smartwatches also offer similar functionality at more affordable prices. This news came into the spotlight after Apple officially reintroduced the SpO2 monitoring feature through a new mechanism on its latest devices.

This feature was previously removed due to an import dispute, but is now available again through integration with the iPhone via the Health app. Although access is more limited than before, this feature's arrival has been well-received.

Not only the Apple Watch, but a number of other smartwatches from different brands are now incorporating similar sensors. This provides a wider range of options for users who want to maintain their health without having to dig too deep into their pockets.

Smartwatches with Blood Oxygen Sensors

As public awareness of the importance of health increases, smartwatches with blood oxygen monitors are becoming increasingly sought after. This sensor works using a technology similar to PPG (photoplethysmography), which is typically used to measure heart rate.

With this device, users can quickly monitor blood oxygen saturation. This feature is very useful, especially for those who frequently engage in physical activity or have certain medical conditions.

5 Smartwatch Alternatives to the Apple Watch

Here are some popular smartwatches that also feature SpO2 sensors:

1. Xiaomi Watch 2 Pro – offers a budget-friendly price with comprehensive health features.
2. Samsung Galaxy Watch 6 – in addition to SpO2, it also has a detailed sleep tracker.
3. Aolon Smartwatch – an economical option starting at IDR 200,000 with standard health features.
4. Amazfit GTR 4 – long-lasting battery and an accurate blood oxygen sensor.
5. Huawei Watch GT 4 – suitable for outdoor sports with a comprehensive monitoring system.

The Importance of SpO2 Monitoring

Blood oxygen saturation can be an early indicator of health. Normal values ​​are usually in the range of 95–100 percent. If it falls below this figure, it could be a sign of respiratory or circulatory problems.

Therefore, the presence of this feature on smartwatches helps users be more alert and take quick action if their condition declines.

Smartwatch Trends 2025

This year, smartwatch trends are not only about elegant designs, but also increasingly sophisticated health functions. Everything from heart rate monitors and sleep trackers to SpO2 sensors are now considered essential features.

With a growing number of smartwatch options on the market, users can choose a device that best suits their needs and budget. The Apple Watch remains the favorite, but other, less expensive and equally functional alternatives are now available.
