While all supposedly have a 5ATM rating, I wouldn't trust anything below 10ATM.

That aside, Garmin has been shoty for me in the past which is why I dumped them, their app never connected correctly.

I'm also not a fan of Garmin's pulse ox readings. Mine is consistently around 10 points below medical grade sensors and my wife's Fitbit. There's tons of complaints across many Garmin watches of their inaccuracies that Garmin seems unwilling to address. This article has zero credibility in my book by having 3 Garmin watches on the list. If you get one, you are likely to be made to believe you have severe sleep apnea and other O2 related issues due to their tendency to read much lower than actual.

Yeah I have a Samsung Watch 6 and I have no clue about its o2 readings.

I know the BP and AFib /ECG readings are accurate. I have a regular BP machine and a Kardia mobile monitor and they always confirm my watch readings
