This watch is of good manufacturing as many of Casio. I found it too small for my arm so I returned. I saw that there is the instruction book in the box of the watch but not French, having said not too disturbing because with little notion in English I and many explicit pictures I still managed to set it. I liked that there was no second hand and yet the needles were synchronized with the second display. You set the needles without winding, you have to press 2 buttons and it rotates. The glass gave a good impression of solidity. The bracelet was plastic. The light illuminates the dial but it's still not Versailles. We must look for even an hour in the dark, but it helps out anyway
