Smiths sectronic Mk1
I’m new to this forum so forgive me if this is a common / impossible ask.
I have come across an old’ish mantle clock that was awarded to my Grandfather for his many years of service to his local Methodist Chapel. It has what I think I have identified as a Smiths sectronic Mk1 movement that doesn’t work. Is a repair possible? Is there someone who would carry out a repair? |

Re: Smiths sectronic Mk1
Hi Wattyman,
It's certainly worth repairing. I'm assuming it doesn't work? Any chance of a picture, front and back?

Re: Smiths sectronic Mk1
The Sectronic mk1 has a moving coil movement, the faults with these are either the coils have become scuffed by the permanent magnet, this usually happens if the clock gets a heavy knock whilst running. I have also seen leaky or dud germanium transistors and a leaky capacitor. It is not usually a mechanical fault.

Re: Smiths sectronic Mk1
Hi, I’ve attached a few images of the clock which I did have dismantled the other day and could do so again if needed.

Re: Smiths sectronic Mk1
Are the battery contacts clean and bright?

Re: Smiths sectronic Mk1
Yes, all clean and ok, I don’t know when it last worked as it was my Grandfathers, he died over 30 years ago!

Re: Smiths sectronic Mk1
These clocks need a flick of the wrist when the hand winder knob(white) is pushed in to kick-start the balance,if it going to run this should set it in motion.If you have a voltmeter you can check for 1.5v across the metal contacts with the battery in situ.Les

Re: Smiths sectronic Mk1
Sorry,I got a bit carried away about a flick of the wrist. The moulded instructions on my model say "press to set hands,release to start" It is the releasing bit and some internal cam action that sets the action going so if the white button is spring loaded and moves freely it should start OK (I thought my clock was a non-runner until I read the instructions) Les.
