The Apple Watch SE 3 Smartwatch 40mm Midnight Aluminum Case with Navy Blue Sport Band S/M S10 Chip 64GB GPS LTPO OLED Retina Display watchOS is compared with five alternative models from the SE 3 lineup: the 44mm Midnight (with an M/L band), Cellular 40mm Starlight, 40mm Midnight (with an M/L band), Cellular 44mm Midnight, and 40mm Starlight. All these devices share the foundational SE 3 architecture, including the S10 chip, 64GB storage, LTPO OLED Retina display, water resistance up to 50 meters, up to 18 hours of battery life, comprehensive health monitoring (heart rate, temperature, sleep stages), and advanced safety features (fall and car accident detection). The primary differences among them lie in the case size (40mm vs. 44mm), band size (S/M vs. M/L), case and band colors (Midnight and Starlight), and the inclusion of Cellular (LTE) connectivity alongside GPS.
