Some key Apple Watch Series 11 features are coming to older watches – will yours get the update?

We're still taking in everything Apple has announced regarding the Apple Watch Series 11, the Apple Watch Ultra 3, and the Apple Watch SE 3, but it's clear that these wearables are going to come with some serious health tracking upgrades.

In the promotional material for the new smartwatches you'll see mentions of hypertension detection (pending regulatory approval), a more insightful sleep score for ranking your slumber, and an AI-powered Workout Buddy for more personalized fitness advice.

Before you rush to upgrade though, you should know that these three features are going to be available on a select number of older watches as well – they're all tied to watchOS 26, which is rolling out to the masses from Monday, September 15.
