Can a more Apple-minded person help me understand if the Apple Watch SE counts as "Series 9"? I don't totally understand how "SE" relates to numerical versioning, but I am also not an Apple person.
Apologies in advance if this question is somehow obvious to others.
"SE" denotes a cheaper, less capable model that is not part of the main sequence of product generation numbering. There have been two generations of Watch SE and three generations of iPhone SE; they're not updated as frequently as the flagship product line. The Watch SE does not have the sensors for EKG or blood oxygen, which are probably necessary for the sleep apnea detection.
