How to find my wife’s watch using my phone.
My wife has late onset Alzheimer’s. I need to track her watch from my phone. Her watch is paired to her phone. How do I track her watch?
iPhone 4s, iOS 9
If the iphone 4S shown above is yours then you have no chance.
You would do better using her iphone and using her find My app.
Or take over her phone totally with your Apple ID then pairing her Watch as a family member on her Apple ID and do what parents do to track their children.
Or buy a newer phone and do the Family pairing.
NB her Watch would need to be a cellular model.
Set up watch for family member

If she is not ready for such drastic intervention you could wait until the inevitable happens. Good luck .
