Apple Watch Series 12 launches globally at $399. Apple Watch SE 3 drops to $199 on Amazon Prime Big Deal Days — ends tonight. Both models go on sale in India at Rs 44,900 and Rs 22,490 respectively, per Amazon India’s live listing. The Series 12 is now Apple’s flagship health wearable, with a 54-hour battery, 5-second heart rate sampling, and new Vitals and Readiness Score features. The SE 3 retains the Series 11’s chip but adds ovulation estimates, sleep apnea detection, wrist temperature sensing, and an always-on display, while omitting ECG, blood oxygen, and hypertension monitoring. It lasts two days on a charge. Neither model supports Apple Intelligence natively. That remains limited to devices with A17 Pro or M-series chips and iOS 18.4/macOS 15.1 or later. Meaning no Series 12 or SE 3 integration, per Apple’s published system requirements. The Ultra 3, also discounted during the sale, includes satellite texting and 5G but no Apple Intelligence either. All three watches ship with watchOS 11.3, released October 6. Amazon’s Prime Big Deal Days end at midnight ET tonight. No official Apple announcement accompanied the pricing shift, it’s a retailer-driven event, not a product launch. The Series 12 and SE 3 were both announced in September and began shipping September 20. PCMag named the Series 12 its Editors’ Choice for iPhone users and rated it ‘Outstanding’. A designation it rarely awards. The SE 3, meanwhile, is positioned as the value-tier option: same core OS, fewer sensors, lower price. In India, the Rs 22,490 SE 3 price matches last year’s launch cost for the SE 2, but with meaningful health upgrades. The Series 12’s Rs 44,900 Indian price is Rs 5,000 higher than the Series 11 launched at. A premium Apple is asking despite identical casing and screen tech. Buyers choosing between them aren’t trading performance for price. They’re trading clinical-grade metrics for accessibility. And right now, Amazon’s making that trade cheaper, for eight more hours.
