Overview
- Multiple outlets report that Apple plans to unveil the Apple Watch Series 12 and Apple Watch Ultra 4 at its September iPhone launch, but Apple has not confirmed specifications or timing.
- Bloomberg and other reporters say both new models are likely to get a new-generation S‑series processor aimed at meaningful performance and efficiency gains to support on‑device AI and expanded Siri features in watchOS 27.
- Supply‑chain coverage and leakers claim the Ultra 4 could significantly expand sensing hardware—possibly doubling sensors—to improve health and fitness tracking, and an upgraded hypertension notification is reportedly under FDA review.
- Details on exterior design remain disputed: some supply reports describe a major Ultra redesign while established reporters expect only modest visual changes and the possible return of a ceramic case option.
- Separately, long-range leaks point to a 2027–28 platform overhaul that would add a new band attachment system and larger battery, a change that could break current band compatibility and shift Apple’s wearables toward deeper AI and form‑factor changes.
