Key point — The Apple Watch SE 3 (8,900 baht) differs from the Series 12 (14,300 baht) by 5,400 baht, mainly in health sensors, battery, and display.
Why it matters — Apple clearly segments health features (ECG, blood oxygen, Readiness Score, high blood pressure alerts) by model, while the SE 3 still serves general users who just want notifications, basic exercise tracking, and always-on display.
Worth watching — How many watchOS 27 new features SE 3 buyers actually get, since some features like Live Rewind are exclusive to the Series 12 and Ultra 4.
