Editorial note
Starts at $799, or $24.99/month over 24 months. Pre-orders began September 9, 2026; in-store availability September 18, 2026. Apple's press release did not specify display size/brightness or a water/dust resistance rating for this generation — both are commonly published for Ultra models but were not confirmed in the primary source used here, so they are left out rather than assumed to match the previous generation.
