Apple Watch SE (3rd generation): full specs

Adversarial re-fetch 2026-07-07. SOURCE = Apple's official Apple Watch SE 3 tech specs page, which confirmed the 40mm reference variant: "Height: 40mm" size block, "Always-On Retina display with OLED and LTPO" (display_type "LTPO OLED"), "up to 18 hours of normal use" (battery_hr 18), "L1 GPS (GLONASS, Galileo, QZSS, and BeiDou)" (gps true), "Water resistance 50m (swimproof)" ISO 22810:2010 (water_resistance_m 50), 40mm "Weight (GPS): 26.3 grams" (rounded to 26), and a GPS+Cellular SKU (models A3326/A3328) that "Supports RedCap for 5G and LTE" (lte_option true). The Health and Wellness list is exhaustive and shows irregular rhythm notifications but NO ECG app, supporting ecg=false. NULLED os "watchOS 26": the Operating System section says only "watchOS" with no version; "26" appears only in the iOS compatibility line ("iPhone 11 or later... with iOS 26 or later"), which is iOS, not watchOS. NULLED release/releaseDate "2025-09": the specs page states no launch date — only "Testing conducted by Apple in July and August 2025 using preproduction" units and footnote "Data accurate as of product launch"; copyright reads 2026. NULLED priceUsd 249: no price appears anywhere on the specs page, and the Amazon CORROBORATION URL returned an Amazon bot-challenge stub ("Continue shopping") with no product content, so neither fetched URL supports $249. 8 of 10 spec keys verified (case_size_mm, display_type, battery_hr, gps, lte_option, water_resistance_m, ecg, weight_g); os and release nulled. Model confirmed exactly as Apple Watch SE 3, 40mm variant — not a sibling/other size. Majority of spec keys survive, so publish=true.
