Watch (kid sized) programmable by iPhone

[boiler717]

We need to get my son a watch that we can use to set alarms for him. He has some kidney issues that are worsening and the doc wants him to go to the bathroom at least every 2 hours. I’d like to be able to set with our phones so we can adjust to leaving the house, daily schedule, etc. However, I don’t want it to have games or at least have the ability to remove games. Any recs?
