Let this be known…

On this day in 2014, the Apple Watch was unveiled.

I don’t feel like there’s any real upside to get a series 8 or 9 coming from a series 5. It’s weird that 5here has been so little new features
 
Since these have a new U2 chip I assume the new album will be preloaded against everyone's will?
 
Yes. I mentioned it because it seemed that without a remote invasive implant, it can be a challenge to measure some things.

Using non-invasive Apple Watch sensors, temperature of the body could be guesstimated. Blood sugar could be guesstimated.
There's no point to 'guesstimated' blood glucose. You either need to know, in which case you need accuracy, or you don't need to know.

The CGM monitors aren't as accurate as a serum blood glucose test, but they are close enough.
 
This is fishy to me. No way that there are so much improvements when the redesign the 10th anniversary is shy one year away. Something is off, if true. Probably Change the parameter of the HR Sensor with an (a) revision and only truly change hardwaregen with the 10th anniversary. In other words using rebranded sensors not new improved tech.
The only people who care about an anniversary model are those in comment sections.
 
This year's main Apple Watch upgrade will be a new processor, which has to date effectively not been changed throughout three successive generations of the device. Apple apparently plans to "heavily tout major gains in processing speed" during its "Wonderlust" event.

Seriously? I honestly just do not get it. I have a series 7 and I can literally think of absolutely nothing that I do on my watch - not a single thing - that isn't effectively instantaneous already as far as CPU performance is concerned. OK, stuff like loading news stories or Shazam-ing a song has network delays but launching wallet, travel apps, maps, contacts, calendar, workouts, activities, reminders, etc etc etc are already so fast that I don't think even a 100-fold increase in CPU performance would be noticeable to me.

Now, if Apple was talking about reduced power consumption then I could understand that but making CPU performance the headline for Apple Watch seems a bit disconnected with reality to me.

Maybe Apple has some super new features or apps coming to Apple Watch that need that performance in which case great - that might resolve my confusion and make things a whole lot more exciting. Only one more day to go until we find out.

Kind of good timing for me since the mic on my Series 7 stopped working about a week ago. Maybe I'll still just pay to get it repaired but this new news about improved sensors might tip me towards buying a new one. A noticeable gain in battery life would also help persuade me to upgrade but that would have to be at least a 50% gain because as someone who doesn't wear his watch in bed that would be enough to get me 2 full days of use if I ever find myself unexpectedly without access to a charger for a single night.

On the sensors it's a shame the rumours don't mention the one sensor that I think is most in need of improvement - the blood oxygen sensor. It's wildly inaccurate for me. I can take 2 consecutive readings with my wrist in exactly the same position and get at least a 5% difference in readings, sometimes even a 10% difference or more e.g. seeing a blood-ox of 85% and immediately taking another reading and seeing 98%. That's just a crazy level of inaccuracy.
 
The CGM monitors aren't as accurate as a serum blood glucose test, but they are close enough.

My wife uses a CGM as part of a closed loop system with an insulin pump. Once calibrated they are very accurate (the difference between the two is usually a slight lag on the CGM as it measures the values in the fat layer not directly from a blood vessel). You can't run something like a close loop system with something that is "close enough" it needs to be to all intents and purposes very accurate. This is important as a major error in the data could cause someone to enter a diabetic coma etc.

The ones that are based off skin contact that are in R&D for watches etc are much more liable to have major variations and be impacted by environmental factors. Washing your hands, spilling a drink near your watch or having a shower would likely spike the values etc. A CGM is much closer to a pin prink test than anything a skin based solution could do.

As much as I'd love to see it happen I think a reliable CGM type solution without some form of cannula is quite far away as the problems you need to solve with skin contact vs internal data is huge.
 
I didn't see any mention of heart rate monitor improvement in presentation or on website. Did I miss something or did it turn out that this "last week" rumor wasn't true?

No, there are no improvements in terms of health sensors.

You’re right, I don’t remember seeing it mentioned either. It might be there - but it’s not a massively “sexy” upgrade to spend presentation seconds on.
 
Blood glucose measurement? Continuous glucose measurement already exists (not Apple) although it actually doesn't measure glucose in the blood but measures glucose in fluids between spaces, so it is an estimate of blood glucose. Does continuous blood glucose measurement exist? I have not heard of such.
Yes I mean continuous measurement by an Apple device would be amazing but I guess the tech isn't quite there yet. It will happen. There are various existing ones that you can wear with a needle protruding into the skin, but they are generally for diabetics rather than the health conscious everyday consumer.
