The Apple Watch Ultra 3 is Apple's toughest and most capable outdoor smartwatch yet, built for adventure and everyday durability alike. This version comes on the refined titanium Milanese Loop band.

• Design & Display: The rugged 49mm titanium case returns with thinner bezels, giving roughly 5% more screen area. The LTPO3 OLED display keeps ticking seconds in always-on mode, peaks at 3,000 nits for direct sunlight, and dims to just 1 nit for comfortable night viewing.
• Performance: Powered by the new S10 chip for faster, more energy-efficient performance.
• Connectivity: Adds 5G cellular alongside satellite messaging, SOS, and Find My — so you can reach help or share your location even off the grid.
• Battery Life: Up to 42 hours of normal use, stretching to 72 hours in Low Power Mode. A 15-minute fast charge adds another 12 hours.
• Health & Software: Runs watchOS with deeper training-load metrics, sleep scoring, and hypertension notifications.
