Depends on the caliber,

Kundo, 49,52,53,54,55 use 0.0032" (0.81mm) HOROLOVAR

Kundo junior's 52,53,5455,56 use 0.0023" (.058MM) HOROLOVAR

Kundo Midget 58 use 0.0022" (.056mm) HOROLOVAR

 

 

The set up is very critical with a 400 day clock. The length of the spring & the position of the lever that operates the escapement is important.Also what is also important to get correct is the thickness of the suspension spring. Too thick or too thin & it becomes impossible to get the clock in time as you run out of adjustment. Even with the correct thickness sometimes it is necessary to thin the springs thickness a touch. Over the years I have repaired & serviced a lot of these movements & because they use very little energy to run for in theory 400 days with one wind everything has to be correct. I highly recommend you invest in a book "400 Day Clock" by Charles Terwillinger

Get a copy of this book The Horolovar 400-Day Clock Repair Guide

It is invaluable for anyone who is going to attempt to repair a 400day clock, although the name 400day clock had to be changed here in England, it was all to do with the trade description act, because some of the clocks could run more or less then 400days when fully wound, so technically it did not run for 400days so they changed it to anniversary clocks. There is also a very good tool that you can buy that helps to adjust the beat of the clock. I found it to be tremendously good and because of its long handle you can adjust the beat extremely finely. 

 

I'm new to this forum. I've uploaded a picture of the beat setting tool for you. I hope it shows up and its not to big

    • I voted leave too, my reasoning was the the EU is undemocratic, no elected officials. I don't regret it but I  am sad that both sides acted like petulant toddlers.  Shameful.  I'm not on other forums but if I was and left this site, would you shun me? Of course not, we aren't petulant toddlers.  
    • This is a type of tool that may be suitable to remove the bezel - though note that I'm pretty sure the watch should be face down - not face up, as in some of the photos of these tools on amazon & ebay! If you try one one of those, put the movement screws back in first to avoid accidents. https://www.amazon.co.uk/Removal-Professional-Remover-Watchmaker-Diameter/dp/B09XCH4QVN?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&smid=A296NCMMFVXSDN&th=1  
    • Hi, I’m constantly asking my wife to help me with removing the stem in order to complete casing. To expand, this is not a challenge for me when the setting lever is secured by a screw (older calibers). However when the setting lever is attached to a spring loaded setting lever axel, like on more modern calibers, I simply don’t see how to apply enough pressure on the button to get the stem out short of putting the movement face down with the dial and hands attached, which I’m loath to do in order to avoid damaging the dial/hands? what technique should I be using? thanks  
    • Many thanks for your advice (being borne in mind at present) & offer Dell. When I was given the clock the plastic anchor was loose on the arbour (it had split at the 'hole') &, after repairing this, I have been trying to determine whether the spindle (pin) should be perpendicular when the pallet is sitting on a flat surface; or whether, when installed, its L-R extremes (or alternatively its tick & tock points) should lie at equal angles from the vertical when moved with spring absent. I can get the clock to run but in every such configuration the top block has to be turned anti-clockwise (from above) by quite a bit in order to be 'in beat' & it always runs fast (despite the pendulum being set to as slow as possible). This makes me wonder if there is any particular feature of/fault in a torsion spring clock which determines which turn direction (if any) is necessary to get it 'in beat'; & whether there would be a different set of settings that would get it running nearer to time at somewhere around the mid timing/inertia position which would then allow tweaking of the fast/slow setting.
    • Now this has happened I bet China or India just to name two will start to produce none genuine parts.  I did. But idiot Boris Johnson failed miserably in his negotiations. The E U stitched up the UK like a kipper. Nigel Farage  offered his help but big head Boris declined. So this is why we are in this mess all because Johnson wasn't clever enough.
