If replacing a number 54 barrel, with a 54 barrel it would be the same dims.

Hi
I have an old ship clock that I need a new barrel and main spring. It does not have any markings to tell me a size. The outer dimension with the teeth are 34.5mm and the other is 32mm without teeth. There is 73 teeth over all. What size do I need?

Thank you

Hi. I was wondering if you could help….I need to replace a barrel on a FHS mechanism but the backplate is just stamped with ‘8’ which I can’t seem to find anywhere. Did / do they make barrel No.8 or does it sound like it might be from a different manufacturer? Thanks for your time

I just removed 2 barrels from a hermle 150.010 mouvement from 1962 with a ‘8’ stamped on both caps. I did not take the springs out of the barrel since they where still clean and ok. You can measure the spring well when still inside the barrel. One string is 17 x 0,40 x ~1200 , and the other is 17 x 0,38 x ~1200 mm. Hope it helps. Greatings from belgium.

What is the Mainspring & barrel number of a Hermle 1051-020? I expect I will find replacing the barrel easier than the spring! All help received with thanks.

Should I be able to remove the mainspring barrel intact from a Kundo Torsion Clock? I can wind the mainspring and let down the mainspring but the barrel never seems to rotate. I’m thinking if I can remove the entire barrel unit, I can see why once wound it does not turn. Not comfortable removing the back plate from the entire movement.
