Apple Watch Ultra 4 brings the most accurate heart rate sensing in a wearable
Apple has unveiled the Apple Watch Ultra 4, its ultimate sports and adventure watch, featuring a new Health Sensing System and the S11 chip. It delivers the most accurate heart rate sensing in a wearable, with measurements every five seconds, plus a new readiness score for athletes. Battery life extends to 45 hours for outdoor workouts, and the on-device GPS is the most accurate in a sports watch. A redesigned Health app with a Longevity tab and Health Age arrives later this year, alongside Audio Intelligence features and Siri AI powered by Apple Intelligence.
With powerful health and fitness insights including readiness, new intelligent features, and its large, bright display, Apple Watch Ultra 4 is designed to support you wherever you go, from your workouts, to adventures, to everything you tackle in a day.

The Ultra 2 was sold to me as the watch that can do Siri without network connectivity. That was very useful to me to leave reminders for stuff I think about while on a run without the phone.
3 years later, Apple releases the OS 27 versions and Siri got improved to the point where it can’t work on-device any more on said Ultra 2
So to get the feature back which I paid for and which was specifically used to sell me the device and which now has been taken away from me, I just have to… buy the next hardware generation?
And how long will that last before they decide to remove the feature again?
Thankfully, the Ultra 4 provides some other compelling features making this less painful, but I would have expected at least a toggle to keep old Siri on the old watch. New Siri over the network is impossibly slow and buggy (I made the mistake of installing the betas, so there’s no way back now)

The first thing they mention is the "great" battery life and it is still only just over 2 days, great.

Dear Apple,
I want to send you my money, but your expensive watch I want to buy is f**ing massive and my wrist is normally sized. I don't really understand why this is still an issue since it's been 4 years.
Thanks,

The 4th generation heart rate sensor is quite interesting -- Apple Watch used to sample every ~5 minutes, and now it's every 5 seconds (basically continuous). I think that'll enable a lot of interesting health & wellness use cases.

Had this thought during the presentation. How is the “rewind” feature legal? Don’t a lot of states have laws against making secret recordings?

The only thing keeping on a Garmin is that my OG AW Ultra probably won't last a mountain 50 miler (I've used it for easier 50 mile races). If it truly lasts anywhere near 45 hours, even my old, slow ass could knock out 100 miles in that time.
Plus satellite comms on the AW (which I'd have to spend money to upgrade the 965 to get that feature). I just might pick one up next week.

"A batter you can't outrun" actually the gen 1 Pebble from literally 2013 still runs circles around this thing.
