Apple Apple Watch Ultra 3 Review: £799 - Is It Worth It?

At £799, the Apple Apple Watch Ultra 3 is not an impulse purchase. Released September 2025, this smartwatches enters a competitive market where value matters more than ever. I've been using it as my daily driver for the past eight weeks—not just testing it, but actually living with it, integrating it into my workflow, and discovering where it delivers and where it disappoints.

This isn't a specs rundown or a glorified press release. This is what you actually need to know before spending £799. Whether 72-hour battery justifies the price tag. Whether the real-world performance matches the marketing promises. And whether this device will still feel relevant in two years, not just two months. See £799 on Amazon

First Impressions: Unboxing and Setup

There's a specific feeling when you unbox a premium product—that moment when the packaging itself signals quality. The Apple Apple Watch Ultra 3 makes a strong first impression. The box has weight and attention to detail that cheaper products skip.

Setup took about 20 minutes from unboxing to fully operational. That includes connecting accounts, updating firmware, and personalizing settings. Compare that to the hour+ I've spent wrestling with competitors, and you start to see where the premium price begins to justify itself. Compare setup with alternatives

The 72-hour battery feature, which I initially dismissed as marketing speak, proved genuinely useful. Not revolutionary, but the quiet kind of friction-reduction that separates good products from merely adequate ones. By day three, I had stopped thinking about it—which is exactly how good technology should work. See £799 on Amazon
