Apple Watch Ultra 4 49mm Titanium Black Ocean Band Black

The Apple Watch Ultra 4 pushes the limits of connected endurance with an exceptional battery life now reaching up to 50 hours of everyday use and up to 84 hours in low power mode. For the most demanding athletes, it offers up to 18 hours of tracking in standard workout mode and up to 45 hours in Ultra Extended workout, enough to see a runner through an entire ultra-trail.

This new generation also introduces an all-new Health Sensing System, featuring redesigned optical and electrical sensors paired with the S11 chip, delivering the most accurate heart rate sensing ever built into a wearable. Heart rate variability is now measured every five minutes, with background readings every five seconds, delivering 60 times more heart rate readings and 24 times more HRV readings than Ultra 3. This wealth of data powers the new readiness score, calculated every morning from activity, vitals, and sleep, to help users know whether to push harder or ease off.

Built for adventure and performance, the Ultra 4 features an aerospace-grade titanium case, a sapphire crystal display reaching up to 3,000 nits of brightness, and meets the MIL-STD-810H military standard to withstand the harshest environments. It carries a WR100 rating, suitable for recreational diving down to 40 meters as well as high-speed water sports, and features an IP6X rating for dust resistance.

The high-precision dual-frequency GPS, paired with the customizable Action button, makes this watch the ideal companion for running, cycling, and swimming, with automatic multisport tracking and advanced metrics like running power, SWOLF score for swimming, or cycling power zones. Out in nature, the Backtrack feature, offline maps, and the Compass app provide confident navigation, while the Oceanic+ app transforms the watch into a full-featured dive computer.

On the safety side, Apple Watch Ultra 4 includes satellite communication features that let users contact emergency services and share their location even without network coverage, alongside Fall Detection, Crash Detection, and Emergency SOS via satellite.

Available in natural or black titanium with a 49mm case, Apple Watch Ultra 4 stands as the ultimate connected watch for athletes and adventurers seeking absolute performance and reliability.
