At least one next-generation Apple Watch model will start using resin-coated copper, allowing for a thinner logic board.The resin-coated copper offers improved durability, water resistance, and additional internal space for other components and sensors.The extra space is valuable for upcoming health features like blood pressure sensing and non-invasive blood glucose monitoring.There is still uncertainty about the launch of the redesigned 'Apple Watch X' and the Apple Watch Ultra 3.
