Can anyone here help. I am a horological novice and I am stuck trying to buy a replacement spring.
I have just joined and started Bob’s course, i bought an old smiths time only, chrome desk clock. The main spring needs replacing and I cannot seem to find anyone who can supply a replacement of the correct size. I am not sure of the thickness, but the other two dims are 8mm x 55mm. It does not have a loop at the end, the original has the spring folded back, which is enough for it to catch.
Can anyone direct me to a supplier?

Have you tried Timesavers, Ronell Clock, or R & M Imports?? They are my main suppliers of mainsprings. Contact them and get one of their catalogs.January 12, 2017 at 1:56 am #64240mowesthamParticipant
Many thanks, I’ll try today.

The sites that Bernie gave are great here in the States. I looked up your location from when you joined the course and see that you’re over in the UK so you might also want to try Cousins over there at https://www.cousinsuk.com . I know Paul (Arutha) who also lives in the UK runs into a lot of Smiths clocks but not sure where he purchases his springs from. Guessing Cousins though.

I do buy from Cousins and Meadows and Passmore although their order system is a little odd. I was quite lucky and bought a job lot of older Smiths mainsprings so have not needed to order one for a while.
The main thing you need to measure is the thickness of the mainspring. I know on all the smiths timepieces I have worked on the mainsprings dont have a fixed loop, they are just folded back but they are rounded at the fold to fit the post. A loop end would work just as well.
