Smiths Wall Pendulum Clock

[Kevin W.]

Looks like a power issue, pendulum not moving strongly.

"Recently" was 3 years ago according to the OP, but you are right that no one knows what was done in the 'service'. From the OP's first post, in recently stopped because of a broken suspension spring. So, there is a legitimate reason other than wear or lack of lubrication for the movement to have stopped working. If the replacement suspension spring is too long, there could be rubbing on the crutch foot, but the pictures and video are too dark to tell. If not that, the pallet bridge was removed, so the escapement may not be working well.

Thanks to everyone for their comments. The clock has been going now for 24 hours on my workbench, but it has done this before!! Before I take more radical action I am going to buy a new suspension spring. The current one does look a little twisted and was supplied by a clock repairer in France ( not the one who apparently serviced it!). When I get this I will see what, if any difference, it has made. Regarding the noise from the spring when winding when almost totally unwound, I will video it when I next wind it.

A thinner suspension spring might help your pendulum amplitude a bit.

Thanks Shutterbug. While I wait for a new suspension spring with a thinner spring, the clock has been running on my bench continuously for over 60 hours. I will wait until it runs down and then add the hands and video winding the spring. Hopefully the new suspension springs will come before long.

It ran on my work bench for 10 days without the hands - now I have added the hands and will see how it goes over the next week. Waiting for the new suspension spring to arrive - held up by customs checks at the border at the moment!!! Thanks again for your advice - if there is still a problem after changing the spring I, I will start checking where it is losing power as per suggestion by Simon and after that maybe a complete dismantle and clean.
I was incorrect about when it was serviced - it was 5 years ago and cost just over €500!! . As far as I can make out, they did repairs to the anchor and to some bushes and they mention a spring but no more details.
