Apple has unveiled three new smartwatches — the Apple Watch Series 11, Apple Watch Ultra 3 and the latest Apple Watch SE. Here’s what’s new across the line-up.
The Apple Watch Series 11 is Apple’s thinnest smartwatch yet, but adds more health and connectivity features.
It can now warn of high blood pressure and hypertension, alongside a new Sleep Score that factors in sleep duration, bedtime consistency, wake-ups and time spent in each stage.

The device supports 5G cellular for faster connections and improved efficiency. Battery life stretches to 24 hours, with fast charging providing around eight hours in just 15 minutes.
It comes in Jet Black, Silver, Space Grey and Rose Gold, with polished titanium options also available.
The Apple Watch Ultra 3 introduces the largest and brightest Apple Watch display to date, with thinner borders and an always-on screen that now shows ticking seconds.
The rugged titanium design is available in Natural and Black finishes.
New safety features include built-in satellite connectivity for Emergency SOS, Messages and Find My — with three years of service included.
Ultra 3 also adds hypertension alerts and the Sleep Score found on Series 11. Battery life is rated up to 42 hours, or 72 hours in Low Power Mode.
The entry-level Apple Watch SE now runs on Apple’s S10 chip and, for the first time, includes an always-on display.
It gains watchOS 26’s new wrist-flick gesture, letting users dismiss notifications, silence timers or end calls without touching the screen.

Health tracking has also been expanded with wrist temperature sensing, sleep apnea detection and the same Sleep Score introduced across the line.
Battery life remains at around 18 hours, but charging is twice as fast as before — eight hours of use from a 15-minute top-up.
The Apple Watch SE is offered in aluminium finishes of Starlight and Midnight.
All three models are available to pre-order now, with deliveries starting Friday, September 19.
