**The Apple Watch Series 10 is the most refined smartwatch Apple has ever made.** It's not the biggest leap — if you have a Series 9, you can probably skip it — but for everyone else, it's the best smartwatch, full stop.
Who Is This For?
iPhone users who want the best smartwatch experience, period. Whether you're tracking fitness, managing notifications, or monitoring health, the Series 10 does it all better than any rival.
Design: Finally Thin
After years of chunky watches, Apple has made the Series 10 their thinnest at just 9.7mm. It's a night-and-day difference on the wrist. The 46mm model in particular looks and feels fantastic — it sits flat under a shirt cuff, and the larger display makes everything from text messages to workout stats dramatically easier to read.
The Display: Stunning
At up to 2,000 nits of brightness, this is the brightest Apple Watch ever. We had zero trouble reading it in direct sunshine on a beach in Brighton. The black bezels are razor-thin, giving the screen an edge-to-edge look that photographs don't do justice.
Fast Charging: A Game Changer
The 18-hour battery life is the same as always — enough for a day, not quite enough to not charge daily. But fast charging changes the equation: 30 minutes on the magnetic puck gets you from zero to 80%. A quick top-up while you shower is all most people need.
Health Features
Sleep apnoea detection is the headline new health feature, and it's genuinely useful rather than gimmicky. Combined with existing ECG, blood oxygen, and temperature sensing, the Series 10 is a capable health companion. Note that blood oxygen monitoring remains disabled in the US due to a patent dispute — UK users get full functionality.
The Verdict
The best smartwatch for iPhone users, and it's not close. The thinner design, massive display, and fast charging make it feel like a genuine generational upgrade. At £399 for the 42mm and £429 for the 46mm, it's an investment — but one that will last you years of watchOS updates.
