WatchOS 10 supports phones as old as iPhone XR, etc. Not sure what the requirements will be for WatchOS 11. Maybe XR again?Oh damn! My kids still use cellular Apple Watch SE 1st gen. I usually 'cycle' through my Apple devices fast enough to not get left behind on updates
I assume there will be no issues pairing iOS18 with a watch permanently stuck on watchOS 10? Might sound like a silly question but I've never been in this situation before. And upgrading to new cellular models for two kids is a $600 investment.
