This is a CASIO DBX-112 Databank wristwatch. The battery was replaced before listing, and the display is now working. All side buttons responded. I don't know how to use it, and I'm unsure what the front buttons are for, so I haven't been able to confirm their functionality. Please note that one of the screws on the back is missing. There are minor scratches and discoloration, so please understand. Model/Product Name: Databank Accessories: None
