Clocks, Watches/Jungmans ATO-Mat Mantle Clock


QUESTION: We inherited this battery operated Mantle clock and after over 45 years of good service it stopped. I investigated and found that one of the small 'nylon/plastic' cogs had broken. We love this clock and want to get it repaired, can you advise please?

We live in Cambridge UK.

ANSWER: Finding that particular gear is probably not an option. I'm sure a movement that old has been out of production for decades and no supplier sells that kind of part. In a case like yours we generally replace the movement with a quartz one. I can help you match a new one to your old if you send my a photo of it.

Thank you for your reply.

Thanks for the photo. Your movement is obsolete but you should be able to replace it with a quartz movement. You should also get new hands because yours might not fit the new movement. If you tell me how thick the material that the movement shaft goes through is I can recommend a movement.
Hands are measured from the middle of the clock face to the tip of the minute hand.
