Apple Watch Ultra 4 49mm Black Titanium Case with Burgundy Alpine Loop (Large)

The new Apple Watch Ultra 4 (Titanium case, 49 mm) is the ultimate watch for sport and adventure. A 49 mm grade 5 titanium case houses the brightest display Apple has ever put on a watch, 3,000 nits behind flat sapphire crystal, readable in full sun and dimmable to a single nit for a night in a tent. The all-new health sensors read your heart rate every five seconds all day, and satellite connectivity means you can send for help, share your location or message from places with no mobile signal at all.

Ultra 4 is built for the long day out. Battery life runs to 50 hours of normal use and 84 hours in Low Power Mode, with 25 hours of Extended Workout tracking on full GPS and up to 45 hours in Max Extended Workout. Dual-frequency GPS holds an accurate track through city canyons and dense forest, and 15 minutes on the charger is worth another 18 hours.

Water resistance to 100 metres and recreational scuba to 40 metres make it a genuine dive computer with the right app, backed by a depth gauge and a water temperature sensor. The customisable Action button puts your most-used function one press away, a built-in siren calls for attention when you need it, and the watch keeps working from minus 20 to plus 55 degrees Celsius on the wrist. Dual speakers and a three-microphone array with beamforming keep calls clear in wind.

watchOS 27 brings Siri AI, with broad world knowledge and an understanding of your personal context, along with Audio Intelligence features such as Live Rewind and Siri Recap. 5G and LTE are built into every Ultra 4, so you can train, navigate and stay reachable with your iPhone left at home, and Emergency SOS, Fall Detection and Crash Detection are always on hand.
