Apple Watch Ultra 3: The Ultra 3 keeps its rugged titanium build and 49mm size but boosts brightness from 2,000 nits on the Ultra 2 to 3,000 nits, making it Apple’s brightest display yet. This improvement makes maps, metrics, and apps easier to read in direct sunlight.
It also introduces a new Natural Titanium finish alongside refreshed band colors designed for outdoor and sports use. The Apple Watch Ultra 2 was made with 95% recycled titanium, and now Apple can confidently say their Apple Watch Ultra 3 is made with 100% recycled titanium.
