Apple Watch Ultra 4

The Apple Watch Ultra 4 is the latest evolution in Apple’s adventure and sports watch lineup. It’s powered by the new S11 chip, enabling Siri AI and Audio Intelligence features, alongside a redesigned health sensing system that delivers the most accurate heart rate sensing in a wearable, with heart rate variability (HRV) readings as often as every 5 minutes, and a new Readiness score to tell you whether your body is ready for the day’s effort.

Battery life has improved significantly: up to 50 hours of normal use (up from 42 hours on Ultra 3), up to 84 hours in Low Power Mode, and 18 hours of continuous GPS during outdoor workouts. Two new modes extend workout runtime up to 45 hours. Charging is fast — 15 minutes delivers 18 hours of normal use.

The build features an aerospace-grade titanium case in two finishes (Natural and Black), with a sapphire crystal display resistant to scratches and reaching up to 3000 nits of brightness, 100m water resistance, and MIL-STD-810H military-grade durability. It also includes built-in satellite communications for emergencies when off the grid.
