The Casio GR-15 is a wristwatch manufactured by Casio.This belongs to a series of collectible game watches by Casio.There are mild scratches on the case.The crystal is in good condition.The case back belongs to a Casio GR-5 and NOT GR-15 unfortunately.The watch works.NO BLEED which is an issue with most of these watches.The sound also works.I have included a NEW Casio After Market strap and Box.Please view pics for confirmation and more detail.

Thank You
