This is a CASIO G-SHOCK, model GW-5600J. The reason for listing it as junk is primarily because the internal battery is dead. As shown in the first photo, it works when a light is shone on it. It was a gift and has been stored for a long time. While it appears to be in relatively good condition, the detailed functions haven't been checked. Please purchase only if you understand that this is a junk item. If you have any questions, feel free to comment, and I will try to check within my knowledge. In that case, I apologize, but I don't know much about watches, so please explain in detail. #JunkItem #CASIO #G-SHOCK #GW-5600J
