I am looking to purchase an older used Apple Watch. I am only really interested in the zones feature. Would anyone know how old I can go and still have access to this feature? When I reached out to Apple support they said only series 8 and the ultra have it which maybe that’s correct but seems crazy.
I do see them as well but it depends of the type of workout? I have a série 7, can see them when I do HIIT but not weight lifting
