This is an extremely rare Ham radio clock from the 1960’s-70’s. It is in good working order. I am not familiar with how it exactly works, but something very interesting about it is that when I removed the battery the clock continued to work for some time thereafter. I just thought that was unusual and wanted to share. I am offering the rare unit exactly as pictured and at no reserve. Please look at all the pictures closely and ask all questions prior to bidding. Thanks
