There are a lot of watches in our family, and Casio is not a rare guest, my son checked out these watches, they look great on his hand, and most importantly, they do not interfere, they are completely weightless. They came in a box with a dubiously printed Casio logo, and we tensed up a little, and if it was a leftist, but the watch itself, if a replica, is of awesome quality. There is also a response of the Casio logo when the key is pressed, and a small letter U at the very bottom of the dial, and a branded non-hoarse beeper. Good ringing hour signal and key response. In general, for incomplete two thousand excellent hours for a child!
