I have a pair of lovely 1970's (I think) mechanical Adrem jump hours. Both were running when I picked them up (very cheaply so they don't owe me 'owt), but they have now stopped ticking. Does anyone know of someone who could service them for not crazy money? Or anyone on the forum who does this type of thing? I'd love to get them going again. Thanks in advance for any help or advice you can give.
