Apple Watch Ultra 4
The frozen lake at dawn, the summit at 4 a.m., the dive at 40 meters — the Ultra 4 shows up to every outing where a regular watch would have already tapped out.

Designed for mountains, diving, and intense training — not just the walk to the subway.
Battery life built for long outings
The kind of battery reserve that lasts a full day outdoors, not just an afternoon at a desk.
Advanced sports tracking
The metrics a serious athlete or outdoor enthusiast will actually check after the effort.
Who is it for?
For those who push battery life and toughness to the limit — sport, outdoors, diving — and for whom a standard watch simply can't keep up.
