Durowe 441 missing incabloc lyra spring

Recommended Posts

Hey there, I'm new to the forum and I have a question:

I recently started experimenting with watchmaking.

For my first project, I purchased a cheap and old Laco-sport with a Durowe 441 caliber.
I strip the movement down, cleaned everything with lighter fluid, oil the parts that needed oiling and put everything back together.

When taking apart the shockproof jewel from the balance wheel, I somehow managed to loose the brass clip that retains the whole system together.

So my question is, how can replace that missing brass clip (I believed it's called a lyra-spring)?

Thank you.

Could it be possible otherwise to bend a click spring (I have spares) to use it as a replacement?

No. Shock springs are much thinner. It is always recommended, especially to beginners, to work on all kinds of springs within a clear bag.

All right, I found a new shock spring on ebay. Do you care to elaborate on how can I work with a clear bag? Thanks

Just poke in it tweezers and pegwood as needed, it anything pings, which be reassured is a common occurence, it won't be lost.

    • This is a very valid point and a subtlety that I was unaware of until fairly recently, learning all the time, the video below explains this point well:  
    • You don't have to use his special tester. Any good multimeter would work.
    • Yes, it looks like GT Revue 30. Doctor, You can not replace escape wheel by the dimensions You listed. One needs to know much more things like number of leaves of the pinion and it's diameter, the position in high of the table and the pinion, the hight between the pivots, the exact pivots diameter... And then, even if suitable wheel is found, one will need to know how to adjust the pallets position correctly. Restoring antique movements is something different than replacing parts. In older movements parts are not interchangeable, this means spare parts do not exist. Here the case is different, but still escapement adjustment will be needed if a wheel from a donor is found. So may be it will be easier to restore the donor for You...Restoring antique movements usually means making of the parts needed and this requires knowlage and working on lathes skill. In this case repivoting of the wheel is the natural solution, but there is a long way that one must walk untill getting ready for such work.
    • I was looking at Essence of Renata, a chemical used a lot for cleaning hairsprings: "Specially prepared solution for degreasing watch and instrument components. Indispensable for degreasing hairsprings." Looking at the MSDS you can see this is just pure n-Heptane, so could be an option for those who don't want to use the chlorocarbons or hexane?     HF6013 - Horological Essence COSHH Safety Data Sheet Horological Essence_0.pdf
