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.

SE is a line orthogonal to their flagship models. Usually it means they took the enclosure from a previous watch and shoved some improved guts in it. Apple Watch SE is similar to Apple Watch Series 8 in terms of processing power but externally (screen, sensors) it’s like Apple Watch Series 4 or thereabouts.

Steve Jobs must be turning in his grave over this dogawful naming scheme.
