Apple Watch Ultra 3 UK release date
At tonight’s astonishing Apple event, the Apple Watch Ultra 3 was unveiled. Typically for Apple, it can be pre-ordered starting on September 15th.
Apple Watch Series 11 UK release date

As a film enthusiast, I can hardly contain my excitement as I learned about the upcoming Apple Watch Series 11 during today’s Apple event! Mark your calendars for next Monday, 15th September, because that’s when you’ll be able to pre-order this marvel of technology.
Apple Watch Ultra 3 vs Apple Watch Series 11 UK price

The pricing for the brand-new smartwatches remains unchanged, with the Apple Watch Series 11 starting at £399 and the Apple Watch Ultra 3 costing £799.
Why does the Apple Watch Ultra 3 cost approximately £400 more than the Apple Watch Series 11? Essentially, the Apple Watch Ultra 3 is designed to deliver a superior, focused experience on health and fitness for those who prioritize these aspects seriously.
The Apple Watch Ultra series comes with bigger and more vivid screens, extended battery durability, enhanced GPS functionality, and a construction robust enough to handle even the toughest sports. It leverages strong materials such as titanium and sapphire crystal for longevity, and it boasts an impressive 100-meter water resistance.
Apple Watch Ultra 3 vs Apple Watch Series 11 battery life
One notable advantage of the Apple Watch Ultra series is its extended battery life, which makes it particularly appealing for individuals participating in intense sports such as ultramarathons, Hyrox, and 24-hour Tough Mudder races. Additionally, this feature eliminates the need to charge your smartwatch nightly, making everyday use more convenient.
The Apple Watch Series 11 can last for about 24 hours after one full charge, while the Apple Watch Ultra 3 is capable of providing up to 36 hours of battery life with a single charge.
Enhanced charging technology, initially featured on the Apple Watch Series 10, that’s particularly advantageous for individuals who heavily depend on their smartwatch around the clock, will be integrated into both upcoming smartwatches.
Apple Watch Ultra 3 vs Apple Watch Series 11 display size

Although the screen size of the Apple Watch is notably smaller compared to an iPhone, it’s crucial for us as users to be able to quickly view notifications and updates without having to look directly at the device. Given this, many smartwatch users have expressed interest in larger display sizes on the latest versions of the Apple Watch.
The new Apple Watch Ultra 3 boasts an impressive upgrade in its display features! Sporting an OLED screen and a resolution of 422 x 514 pixels, it surpasses the previous model’s 410 x 502 pixel resolution. To add to that, the bezel has been narrowed down, thereby increasing the display size without altering the dimensions which remain at 49mm in height and 44mm in width.
On the new Apple Watch Ultra 3, you’ll find an improved LTPO3 display. This technology lets the watch screen adaptively change its refresh rate, providing a more fluid visual interaction by adjusting how often it updates the displayed images per second.
As a movie enthusiast, I’d say the new Apple Watch Ultra 3 truly shines with its display, boasting an incredible maximum brightness of 4,000 nits – that’s significantly brighter than the Series 11, which has a max of 3,000 nits.
Similarly to its predecessor, the Apple Watch Series 11, retains the same dimensions: standing at 46mm tall and measuring 42mm across in width.
According to the Apple iPhone 17 lineup reveal, the Apple Watch Series 11 is anticipated to feature Liquid Glass Flow technology in its display.
Apple Watch Ultra 3 vs Apple Watch Series 11 health features
The Apple Watch Ultra 3 and the Apple Watch Series 11, two models in the lineup, are equipped with the latest S11 chip, sporting a dual-core CPU and offering 64GB of storage. This empowers them to handle data and apps swiftly, and provides ample space for storing information. The new chipset is instrumental in enabling the impressive health and fitness features they offer.
The fundamental purpose of the Apple Watch is to monitor your health closely, and one of its intriguing new health features is the high blood pressure alerts. Just like the sleep apnea detection feature, these high blood pressure alerts will give users early warnings about potential hypertension. In fact, Apple anticipates that within the first year of owning an Apple Watch, up to a million people could receive alerts about possible high blood pressure.
As a self-proclaimed film enthusiast donning my watch nerd hat, I’m excited to share that Apple has revived the blood oxygen tracking feature for both the Apple Watch Ultra 3 and the Series 11!
Apple Watch Ultra 3 vs Apple Watch Series 11 fitness features
Apple has switched to a Mediatek processor for improved performance that doesn’t sacrifice energy efficiency. Additionally, the Apple Watch Ultra 3 and Apple Watch Series 11 boast enhanced network stability as well.
The new Apple Watch Ultra 3 now features satellite connectivity, making it ideal for fitness enthusiasts who work out in secluded or disconnected areas. In terms of location tracking, ultra-wideband technology provides exceptional accuracy.
Our verdict: why we’d recommend the new Apple Watch Ultra 3
As a smartwatch user myself, I can’t stress enough the importance of battery life. Constantly monitoring my health, fitness, and notifications like iMessages, the last thing I’d want is for my smartwatch to run out of power in the middle of the day, leaving me without essential information or alerts.
In simpler terms, the Apple Watch Ultra 3 offers an impressive battery life of up to 36 hours on a single charge, making it ideal for intense activities such as ultramarathons, but also practical for more casual situations like long-distance travel, work shifts where step tracking is important, and even spontaneous overnight stays, where you can still monitor your sleep patterns.
Apart from boasting an extended battery life, the Apple Watch Ultra 3 also impresses with its larger and brighter screen. For those who heavily depend on their smartwatch for intricate visuals like health data, you’ll find delight in the new LTPO3 display that offers enhanced resolution and excellent power savings. Moreover, the Apple Watch Ultra will debut with unique watch faces upon its release.
Can’t wait until the new release? You can get your hands on the Apple Watch predecessors.
