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.
Ok I found more info so if anyone is interested the Zones update was part of OS10 for the watch and it looks like series 4 is oldest of the regular watches that can run it and all SEs can run it. Thank you everyone for your help!
