At its fall product event today, Apple updated its line of smartwatches, including the introduction of features for monitoring blood pressure and analyzing the quality of your sleep.

The Apple Watch 11 is supposed to be able to alert users about "possible hypertension" by using data from an optical heart rate sensor "to analyze how a user’s blood vessels respond to the beats of the heart," per its announcement.

According to Apple's presentation, the smartwatch will look for chronic hypertension over 30-day periods. Apple's presentation noted that the Watch Series 11 won't be able to identify all hypertension, but the company said that it expects to notify over 1 million people with undiagnosed hypertension during the feature's first year of availability.

The feature is based on machine-learning and training data built from multiple studies examining over 100,000 people combined, Apple noted.

Apple said it expects the blood pressure monitoring feature to receive Food and Drug Administration clearance soon and to get approval in 150 regions this month.

The new watch will use a 5G modem and also introduce a feature that provides wearers with a "sleep score" that's based on the duration of their sleep, the consistency of their bedtime, how often they awaken from their sleep, and how much time they spend in each sleep stage. The Watch will analyze those factors every night and then provide a breakdown of how each score is calculated. The feature is based on an algorithm tested with 5 million nights of sleep data, Apple said.

Other updates include the use of INX glass with ceramic coating that's supposed to make the Watch Series 11 two times more scratch-resistant than its predecessor.

The Apple Watch Series 11 is $399.

Apple Watch Ultra 3

Also new this year is the Apple Watch Ultra 3, which also supports hypertension notifications and sleep scores.

Another one of the biggest updates here is the bigger display within the same-size case, created through the use of smaller bezels. Apple didn't confirm the size of the screen, but the Watch Ultra 2's screen is 49×44 mm.

The new OLED screen is also supposed to be brighter when viewed from an angle, compared to its predecessor. Again, we don't have specific numbers yet, but the Ultra Watch 2 claims a max brightness 2,000 nits.

In addition to supporting 5G and satellite connectivity, the Watch Ultra 3 is also supposed to have double the radio and antenna strength of the Watch Ultra 2, thanks to new designs.

Apple's priciest watch also has a bigger battery, with a 42-hour battery life claim. Its predecessor claims up to 36 hours of battery.

The Watch Ultra 3 will be $799.

Finally, Apple is also upgrading its budget Apple Watch SE with an Apple S10 chip, a notable upgrade from the S8 used in the preceding Apple Watch SE 2. With this chip, the Apple Watch SE 3 will be the first Watch SE to have an always-on display.

Additionally, the SE 3 will get the ability to track sleep scores and deliver sleep apnea alerts, like the Watch Series 11 can. It also adds the abilities for retrospective ovulation estimates and wrist temperature monitoring, "which can provide insight into overall wellbeing and adds to the other key health metrics available in the Vitals app," Apple's presentation said.

Apple's new budget smartwatch has the same 18-hour battery claims as the SE 2 but is supposed to be able to charge twice as fast.

The Watch SE 3 is $249.

Preorders for the new Apple Watches start today, and the devices will be available on September 19.
