The Verge reports that watchOS 27 will support only Apple Watch Series 10 and later, Ultra 2 and later, and SE 3, dropping Series 9, original Ultra, and earlier models previously covered by watchOS 26. Parallel changes in iPadOS 27 remove support for multiple M1 and earlier iPad models including 3rd through 5th generation Air and 8th generation base iPads. A single unverified report from 9to5Mac also notes the watchOS support reduction.
