Camera Setup: Houses a high-resolution 8MP front-facing camera optimized for crisp, face-to-face video conferencing with parents.

Durability: Rated with an IP67 water and dust resistance certification, safeguarding the internal tech against hand washing, rain, and playground puddles. 

Battery & Power: Packed with a generous 800mAh high-density battery utilizing convenience-focused magnetic pogo-pin charging points (takes ~4 hours to completely fuel). 

Stranger Call Shielding: Parents can toggle a security firewall that restricts incoming text messages and voice calls strictly to pre-authorized contacts inside the watch's phonebook.

Class Mode Scheduler: To prevent class distractions, parents can program rigid "Do Not Disturb" time frames (e.g., school hours), locking down the watch UI into a simple clock interface while maintaining SOS background availability.
