This is an early model of a SEIKO radio-controlled solar watch. The band is original, but the band loop is missing because it was made of a material that deteriorated easily. Instruction manual included. Operation has been confirmed, but the secondary battery doesn't hold a charge well and needs to be replaced. For those who like SEIKO, those who don't want to wear the same watch as others, and watch enthusiasts. I hope you will consider purchasing it. Please understand that this item is sold as-is.
