This anniversary clock is an electronic battery operated. It was a gift from my wife and happily did its thing for a number of years and then suddenly the rotation of the weights just quit. I had a look at it but couldn’t determine what had happened.
I purchased a replacement unit while on vacation this year in Campbell River on Vancouver Island from Brian Zirk - Antique Clocks.
I brought the “new” clock home and promptly set it up in place of honour and away it went - no muss nor fuss.
I took the “old” clock down to my workshop and tinkered with it and the rotation unit started again and has been working just fine - go figure!!
