VINTAGE LINDEN BLACK FOREST ALARM CLOCK

VINTAGE LINDEN BLACK FOREST ALARM CLOCK THIS ALARM CLOCK HAS BEEN IN MY FAMILY FOR DECADES; IT USE TO GO ON VACATIONS WITH US WHEN I WAS A CHILD I HAVE NO IDEA HOW IT WORKS AND I DID NOT MESS AROUND WITH ANY DIALS IN THE BACK BUT IT DID START TICKING AFTER I OPENED THE CASE WHILE I WAS TAKING PICTURES AND THE TIME DID CHANGE!? I HAVE NO CLUE HOW TO TEST THE ALARM AND I AM ONLY ABLE TO ASSUME IT WORKS BASED OFF MY RECENT EXPERIENCE BUT AM SELLING "AS IS" FOR PARTS/NOT WORKING SMOKE FREE PET FREE
