Always-On Retina display
Raise your wrist and the
display instantly comes to life. Great screen area to feature a variety of watch faces with multiple
complications.
Always-On technology
keeps the display on so you can see information at a glance. And with a maximum brightness of 2000 nits,
twice that of Series 8 and SE, it’s easier to read in bright sunlight. Detailed watch faces look
stunning, even when your wrist is down. The edge-to-edge design accommodates your favorite complications
and makes tapping, typing, and swiping easy.
The largest display,
with up to 3000 nits of brightness — the brightest display Apple has ever designed. Large enough to see
up to six lines of workout metrics at a glance. Readable even in direct sunlight. Always-On technology
keeps the display on so you can see key information at a glance. The new exclusive Modular Ultra watch
face is easily customizable and shows real-time altitude, depth, or second on the outermost edges, and
Night Mode can activate automatically in the dark.
