Yea I saw that. Thought it was a useful feature at first but I haven’t used it once.not sure where you are, or if you got your 1 before the cutoff date, but if you're in the US, any new watch will not have blood oxygen.

I upgraded last year when the U2 was first released, battery life is better and SOC is more powerful. I had posted my impressions last year, somewhere in here .For those of you who upgraded do you feel it was worth it and why?
Thanks in advance
Pretty much exactly what I see on my U1 and U2, it‘s just that I wear them for around 24hrs and therefore have slightly higher battery percentages when putting them on the charger.I upgraded last year when the U2 was first released, battery life is better and SOC is more powerful. I had posted my impressions last year, somewhere in here .
Battery life for my use case with U1 at the end of about continuous 38hr use was between 25-30%, U2 is about 40-45% with same usage. And I recall that OS upgrades took about 2/3 of the time
Another Pro Tip: if you put your fingers on your wrist, you can know your heart rate at that moment.Hi,
just bought an AW U1 is nearly perfect condition for "small money"...battery life ist near perfect (98%) and I m very happy with the watch. Yes, of course the AW U2 is better, but the changes are minor (to me) and the U2 is definately more expensive. Do I miss any function the U2 has compared to the U1? No, not really. Probably wating for a AW U3 in 2025, hopefully with a bigger step forward
Btw, sleep apnea detection is nice to have, but actually If you are a bit familiar with the medical field, you could identify sleep apnea episodes by yourself. The U1 can detect: breath frequency, heart rate and blood oxygen. If you can map all three parameters (e.g. temporary breathing stops + significant heart rate variability + blood oxygen drops <90%) you could identify sleep apnea by yourself.
Kind regards
My father has been diagnosed with sleep apnea, if you look at his blood oxygen records you don't draw any conclusions. We are talking about a dozen random measurements over the course of an entire night.

Now seriously...
My father has been diagnosed with sleep apnea, if you look at his blood oxygen records you don't draw any conclusions. We are talking about a dozen random measurements over the course of an entire night.
He also has a minor heart problem, so the heart rate variability data would also be useless. And, as I said before, in this case we're talking about only 5-6 HRV readings during the night... More if you enable AFib history.
So... In my opinion... I do not find it realistic that a normal user (or even one with medical training) could draw any conclusions from the data available up to now with sleep apnea detection.
I find it more realistic that one might think that one has this illness due to basic symptoms such as sleeping poorly and so on. But of course, for every one who is right, maybe there are 50 who are not...
