Apple Watch Series 10

Released on 20 September 2024, the Apple Watch Series 10 has proven to be an exceptional smartwatch. Here are its key specifications:

The Series 10 is a fantastic smartwatch, with our only major critique being its 18-hour battery life, which lags behind competitors. Otherwise, it’s a stellar choice for UK users. Personalise it with our Apple Watch Series 10 straps in 42mm and 46mm sizes.

Starting at £399

Apple Watch Ultra 3

The Apple Watch Ultra 3 has not yet been released, with analysts predicting a launch on 9 September 2025 alongside the iPhone 17 series. The delay from 2024 is attributed to Apple’s focus on developing advanced health features, such as blood pressure monitoring and possibly enhanced sleep apnoea detection, which faced regulatory hurdles previously.

Despite its unreleased status, rumours provide enough insight to compare it with the Series 10. Below are the likely differences.

Display

The Apple Watch Ultra 3 is expected to feature a larger 2.12-inch display compared to the Series 10’s 1.6-inch (42mm) or 1.8-inch (46mm) screens. While earlier speculation suggested a microLED display, Apple reportedly cancelled this project in 2024, so the Ultra 3 will likely use an advanced OLED, potentially brighter and more efficient than the Series 10’s LTPO3 Retina display.

Battery Life

The Series 10’s 18-hour battery life is a weak point, but the Ultra 3 is expected to offer improved performance, likely up to 36-48 hours, as seen with the Ultra 2. Exact figures are unconfirmed, but the Ultra series typically excels in this area, making it ideal for extended use.

Blood Pressure Monitoring

Rumours indicate the Ultra 3 may include blood pressure trend monitoring, a feature absent in the Series 10 due to regulatory challenges. While not providing exact readings, it would alert users to significant blood pressure fluctuations, enhancing health tracking for UK users.

Price

The Ultra 3’s superior features come at a premium. Expected to start at £799, matching the Ultra 2, it’s significantly pricier than the Series 10 (£399 for aluminium, £699 for titanium). The cost makes the Series 10 a more budget-friendly option for most users.
