Overview

• Series 11 and Ultra 3 are expected to debut at Apple’s September event with the S11 system-in-package promising improved energy efficiency and longer battery life.
• Ultra 3 is reported to be the first Apple Watch to support 5G via reduced-capability RedCap networks alongside upgraded satellite emergency features.
• Both models will include new alert-style blood-pressure detection sensors that notify users of potential hypertension rather than providing continuous cuff-style readings.
• Apple is said to be shifting its Watch cellular modem supplier from Intel to MediaTek to enable the power-optimized 5G RedCap connectivity in Ultra 3.
• Supply-chain reports point to a potential high-end Watch redesign in 2026 featuring an underside ring of eight sensors, though those details remain unconfirmed.
