I'd like to get my son an Apple Watch for his combined birthday/Christmas present. He is going to be 13.
He has an old SE iPhone 1st generation (bought 2nd hand).
I'm weighing up buying him a new 3rd generation watch S3/2018. Or whether to buy a reconditioned newer model from CEX.
Wanting to make sure that they are compatible for a bit yet - thinking of iOS updates etc.
What is the best bet?
