Apple is reportedly preparing the Apple Watch Series 12 and Ultra 4 for this fall, but neither is expected to receive a significant design overhaul. The biggest improvements will instead focus on a long-awaited chip upgrade and more advanced health and fitness tracking, while major features like blood-sugar detection remain years away. Apple Watch has settled into a conservative cycle of incremental refinement, even as Apple takes bigger design and technology risks with products like smart glasses and camera-equipped AirPods.
