Kids Sport Watch: Our kids fitness tracker watch does not need to connect to the phone or any app, and it's really easy to set. We integrated the step counting, stopwatch, calories, and mileage inside the watch. Record the kid's sports data. Powerful Battery Life: This kids digital watch has a USB interface. You can use any USB adapter (Such as a smartphone adapter, computer, or Portable Charger) to charge the boys watch. The battery life is about 15 days. Silent Vibrating Alarm: Parents can set up two alarms to remind children to study and rest on time. Whether in the classroom or the dormitory, the child can feel a vibration, but no one else will be disturbed. This is a great choice for students! Reliable Quality: The best kids watch is really light and soft on the skin. The shape is also really adorable. The band has many adjustable settings and is very soft and flexible for tiny childrens wrists. Waterproof Resistant: Boys digital watch has been 5 ATM water-resistant, suitable for washing hands, facial washing, and rain. This is very practical. But it is not recommended to wear it when swimming, in hot baths and in saunas.
