The biggest and brightest Apple Watch display ever. Powered by the all-new S9 SiP, the Always‑On Retina display is 3000 nits at its peak, making it even more readable in harsh sunlight. In low-light situations, it dims to 1 nit. Night Mode now activates automatically in the dark. The large display gives you room to customize your view to suit almost any activity. And a new watch face shows dynamic info like altitude, depth, or seconds along the outermost edges.
 
Apple Watch Ultra 2 is crafted for unparalleled performance. The lightweight titanium case is rugged and corrosion resistant, and it's raised to protect the sapphire crystal from edge impacts.
