Apple Watch Ultra 3: price & specs

Adversarial re-verification against the two fetched Apple pages (specs page = source; buy page = corroboration). Exact model confirmed on both (Apple Watch Ultra 3, 49mm titanium GPS + Cellular, sole configuration). CONFIRMED verbatim on apple.com/apple-watch-ultra-3/specs: "Height: 49mm" (case size (mm)); "Always-On Retina display with wide-angle OLEDs and LTPO3" (display type recorded as "LTPO OLED"); "Multiday battery life, up to 42 hours of normal use" (battery (hr)); "L1 and L5 precision dual-frequency GPS" (gps); "Model A3281: Supports RedCap for 5G and LTE" (lte option); "Water resistance 100m ... under ISO standard 22810:2010" (water resistance (m)); "ECG app" (ecg); "Weight (natural): 61.6 grams" -> 62 g nearest-gram (weight (g)). Price CONFIRMED on the fetched buy page: "Apple Watch Ultra 3 From $799" (the price 799). REMOVED: os was "watchOS 26" but the specs page Operating System section lists only "watchOS" with no version, and neither fetched page contains "watchOS 26" (both cite only iOS 26 for iPhone compatibility) — the version was an inference from the press release, which was not re-fetched. release/release date "2025-09" could not be verified — neither fetched page states a launch or availability date; the only dating is "Testing conducted by Apple in July and August 2025" on preproduction units, and the September 2025 date originated from the newsroom press release, which is not among the verified URLs. 8 of 10 spec keys survived (>50%), model exact, price corroborated -> publish remains true. The page this record cites as its source (https://www.apple.com/apple-watch-ultra-3/specs/) is gone: on 2026-09-11 it answered 200 and redirected to https://www.apple.com/watch/, both from a residential connection and from a datacenter on another continent — so the page is gone rather than withheld from one asker. Its second recorded capture of the same figures — apple.com, read 2026-09-11 — still answers, and the figure stands as last read.
