London. Apple has announced the Apple Watch Ultra 3, its most powerful smartwatch to date, with a clear focus on endurance, safety and health tracking. The device promises up to 42 hours of battery life, supports satellite SOS messaging for emergencies, and introduces 5G connectivity for faster and more reliable performance. A new LTPO3 OLED display stretches closer to the edges, offering brighter visuals and improved energy efficiency. Health features now include hypertension alerts and a sleep score, expanding Apple’s preventive health tools. Built from titanium with sapphire glass, the Ultra 3 is designed for extreme conditions while maintaining a premium aesthetic. The watch is available to preorder now, with UK sales beginning on 19 September 2025, starting from £799. The WP Times reports, citing SoFrankfurt.
Why it matters for the UK market
For British users, the Ultra 3 offers crucial features for both urban and outdoor life. The new satellite SOS system could prove invaluable in rural areas with poor mobile coverage, from the Scottish Highlands to parts of Cornwall. In cities like London, the 5G upgrade ensures smooth streaming, messaging and app use even during peak hours. The 42-hour battery life addresses a long-standing complaint among UK commuters who rely on the Watch for fitness, payments and navigation across long days. The sleep score and hypertension alerts also reflect growing NHS concerns around public health, particularly cardiovascular risk. By combining lifestyle convenience with medical-grade insights, Apple aims to strengthen its hold on the British wearables market.
