How accurate is the pulseOx?

Always gives me a reading too low 90-94% while an external devise is in the range of 97-99%

also cant always take a measurement, too many "measuring" and "keep still"  cycles with no results.

The fitting is fairly tight just above the wrist bone

    not sure about its accuracy but mine measures first time every time and I'm mostly between 95 and 100. Mostly 100.

    With the Fenix 6x Pro, non-sapphire, it's spot on, about all of the time.  I have a finger pulse ox I use to use, but now after testing this one very often and looking at the history, I don't need my finger one anymore.  This is within 1 to 2% of a dedicated pulse ox.  I'm actually very impressed.   I wear it on my left wrist, snug, not tight.

    Mine is displaying values between 90% and 99%.

    I only have a pulse ox on my phone Galaxy Note 9 and the phone is always displaying higher values...

    Watch 94 phone 98 etc...

    These values were with 2.20 firmware. I checked again now with firmware 3.0 and the watch showed  value 95 and the phone 93, so they are pretty close.

    I don't know if this is caused by the firmware update...

    My 6X Pro has demonstrated pretty good correlation with a dedicated pulse oximeter.  For the past 24 hours I have been at a steady 4553 Feet above MSL and seen a SPO2 level between about 88% and 94%:

    Considering the reduced Oxygen level at this Elevation, it seems very reasonable:

    Of course, it is important to remember that our watches are not medical devices and should not be relied on in any critical situation.

    Mine seems pretty accurate, though I have no way of verifying it. But it seems to correspond with reality for the most part. I used Sleep Pulse OX last night, and it indicated that I hovered around the mid-90's most of the night, with 2 dips into the 80's, which sounds about right to me.

    I’m curious as well. I just received mine and seeing my nightly spo2 readings go down to 84% through the night (lowest level is 84 and it hits it a couple times, then back to normal. Either the watch or maybe I have sleep apnea?  I guess I’ll monitor it.

    During sleep, I don't know for sure.  But while remaining still I test the pulse Ox on ALL FOUR of my Garmin watches against my Innovo iP900AP unit. They generally show the same saturation, +/- one percent.

    Mine is crap. It shows, just an example,  85% when checked with a medical pulseox is 98%. I have tested in various conditions and in my watch ( 6x pro) is useless.

    Sorry it's not working well for you, mine is still working quite good. I've had 24/7 PulseOX turned on since the COVID thing started, and it's never given me any readings that I felt were wrong - granted, I don't have another pulse oximeter to test it against. But the readings at least seem realistic as far as I can tell.

    I almost wish it didn't work, then I could just turn it off and save the battery life Smiley
