Their measurement workflows differ: Fitbit and Pixel Watch examples emphasize sleep-based readings and trends, while Garmin documents both spot checks and sleep measurement. Treat these readings as wellness information, not a diagnosis, and check the exact model, country, phone, and app support before buying.
How the blood oxygen tracking differs
SpO₂ features are not identical across these watches. Some report readings collected during sleep; Garmin’s cited Venu 2 Plus page also describes an on-demand spot check. That distinction matters if you want occasional readings while awake rather than overnight estimates and trends.

| Option | Documented SpO₂ approach | Other health and fitness context | What to verify |
|---|---|---|---|
| Fitbit Sense 2 and related Sense devices | Google describes overnight measurement. For Sense devices, Fitbit can show the average and range from a recent sleep session. | Sense 2 is described in editorial coverage as offering activity, stress, sleep, heart-rate, and heart-rhythm features. | Confirm support for your exact device and app. Sleep results may take around an hour after waking or syncing to appear, according to Google’s Fitbit SpO₂ help page. |
| Google Pixel Watch series | Google says SpO₂ tracking is automatically added on Pixel Watch series. Google Health can show an average, range, and 7-day graph. | Google’s vitals information lists breathing rate, heart-rate variability, skin temperature, oxygen saturation, and resting heart rate; supported features vary by device. | Check country, device, software, and Google Health availability. See Google’s vitals help page. |
| Garmin Venu 2 Plus | Garmin describes Pulse Ox spot checks during the day or while sleeping. | Garmin also names Body Battery monitoring and health and fitness features. | The cited Venu 2 Plus product page is for Ireland; verify local availability and the features offered for your market. |
Which option fits your priorities?
Choose Fitbit Sense 2 if you want overnight SpO₂ reporting
Fitbit’s documented approach suits shoppers interested in sleep-session averages and ranges alongside other wellness tracking. Google says the readings are estimated while sleeping using red and infrared sensors. The displayed value can take time to appear after waking or syncing, so it is not designed as an immediate spot-check workflow.

Choose Pixel Watch if Google Health integration is the draw
Google describes automatic SpO₂ tracking on Pixel Watch series and a view of averages, ranges, and trends in Google Health. Its vitals feature set is device-dependent, so compare the supported-device information for the particular watch rather than assuming every model has the same health dashboard.

Check phone, country, app, and feature support before buying
A watch’s health feature is only useful if it works with the phone and services you intend to use. Compatibility can affect app access, data syncing, calls, messages, and other smartwatch functions. Third-party watches may offer a less integrated experience with iPhones, and feature availability can vary by model, country, software version, and regulations, according to TechRadar’s 2026 iPhone smartwatch guide. Confirm any specific compatibility detail with the manufacturer.

Understand what a wearable SpO₂ reading can tell you
These watches provide consumer wellness readings, not a medical diagnosis or a substitute for professional advice. Google Health’s guidance states: “For health concerns, consult a healthcare provider.” Do not use a watch reading alone to diagnose a condition or decide whether to delay care; seek advice from a healthcare professional when you have a health concern.
