Essential features and nonfunctional requirements:
- Calendar, time and date, alarms and reminders
- IP67
- Ruby or gorilla glass screen (scratches OK)
- Locked-down phone, texting, messaging, and location sharing
- Ability to call 911
- Minimal apps
- Minimal animation
- Band that's somewhat difficult to undo and hypoallergenic material... silicone seems pretty neutral
- Not disassemblable without tools because the kids I know would have them in pieces in minutes.
- Neither a fashion statement nor a kid group social faux pas
If any existing models fulfill these close enough, then great. If not, then it might be worth entertaining but would need a go-to-market strategy to compete with every other smartwatch mfgr on the market with unlimited funding.
