Default Re: Vintage Clock Bobbin rewind

That is almost certainly a slave clock, please don’t connect it to the mains. That is maybe why it needs a rewind as somebody may have put the mains on it in the past by mistake. It’s an unusual movement that I’ve not seen before.
You will need a master clock to drive it or a slave impulse device. It would be good if you could fit the minute hand and toggle the mechanism and see what time interval it advances by it will be either 1/2 min or 1 min, it looks like 1 min from the photo, with a rocking ‘lever’ advancing 1 min in each direction of the ‘lever’.
Enjoy
