This is an extremely rare SD Dechonpa Godzilla digital watch from Bandai, released in 1989! The item is in its original box and even comes with the original battery (likely is dead and requires a new battery). The SD version of Godzilla raises his arms and lifts his mouth to reveal the time! The box, itself, is a work of art - and is in good shape.
