So I had suspected sleep apnea and consultant arranged sleep monitoring device, quite industrial looking, result was ZERO episodes, not I did not wear my watch at the same time.

My watch regularly flags me below and some long periods.
Does this mean like blood pressure these functions are pointless and inaccurate.

Hi, The watch is not medically certified. There will always be a margin of error. And it also depends on how your wear the watch -if it's too loose/tight and position of the watch. It can happen that it does not get a reading and therefore shows a drop.

Don't take the values literally. Of course, in case of doubt or unexpected results + on how you feel, always consult a physician.

One thing I know - BP is almost 99% accurate, Pulse is 100% accurate, usually finger O2 sensors are more accurate, for general use (as you are not in ICU) the numbers Galaxy watch (mine is 5 pro) giving out are more than enough for basic home use

Agree its directional but at best it is 75% accurate for BP, HR and SPo2 seems pointless.

I calibrate my watch monthly as required with an Omron BP

My blood oxygen on my watch 5 Pro is under 90% for only about 30 secs a night. Certainly no more than a minute. Your 9 mins seems a long time to me.

The same issue with my watch 5 pro.
I'm compare it with two other devices. It gives me almost every time lower Oxygen level. 

During the night is happening to have 10 min on low. 
Some time give me 82 % during the day. Rebooting the watch makes it to 96%. 

Hopefully it will get some updates soon. As far I know same was happened with watch 4 at beginning of the release.

 until midnight i slept without the CPAP mask and after midnight with the mask, u can see that that  my oxigen goes low before midnight but nit after that, I don't have another device to log the entire night for blood oxygen but when oxigen went low i actually woke up and felt like dying, problem is that any supposedly more accurate devices are very expensive and not as easy to sleep with like the watch5 so buying one for that reason only is not really worth it, so far id say that the watch is rather pretty accurate
