Case-in-point all those $20 pulse-oximeters that have become popular recently...they're around +/-6% accurate...medical-grade versions start around ten times that, IIRC.
That's the problem with consumer grade instruments - having a lab grade standard level machine to which said consumer device can be calibrated.
But, I have an iHealth Air Pulse Oximeter which is spot on with three different Watches - OG Apple Watch, Series 2, and Series 5, all of which are reputed to be very accurate regarding pulse.
As to the O2 measurement, I can only hope.
I'm still hoping there's no oximeter capability in the Series 6.
