Can't tell by the video if it's in beat, the only way of telling is to watch the pallets escape at the same time as watching the pendulum rotate.  Have you got the suspension  length right it has to be bang on to the description in the book, the pallet fork also has to be bang on. Have you oiled it, what oil did you use, these clocks work best on little oil but you need to have oiled it in the right places such as escape wheel teeth. Have you tried regulating by its proper means. If you are expecting the pendulum to rotate at a flying speed you can forget that many of these clocks are slow in rotating.

Hi oldhippy i followed what it said in the book and used the template for the spring oiled it with J D Windles medium viscosity mineral oil when you say regulate by proper means what do you mean ? i have turned the regulator towards fast and it still is slow

If you've maxed the regulation and all the adjustments Oldhippy mentioned are good then it sounds like you need a stronger spring. Horolovar is usually great with their info but sometimes not perfect. Just 0.01mm thicker will probably do it.

I have not reach the max limit but i don't think i am far off think i might try a thicker spring thanks nicelsilver

Counting the seconds between every full swing I would say it is a touch out of beat. However as oldhippy recommends you need to measure the suspension spring. Just a tiny amount of too strong or too weak and you will run out of adjustment. 

 clockboy trouble is i don't have a micrometer i have ordered  a thicker spring should arrive today or tomorrow will change that and see what happens, will it being a touch out of beat make much of a difference ,thanks

If it is not in beat the clock might stop, they are very sensitive, it might not happen but it could at any time. I have know them to just stop after months.

As Old Hippy said these clocks are sensitive,  I have set mine up on a level base and run them on but, when moved to the display cabinet they stopped most likley out of level.  The beat setting tool is a must when working on these clocks as it allows you to make very fine adjustments. The tool is also universal and fits all 400 day clocks. So if you intend to do any more buy the tool it will save you time in the long run

Hi Willow. Oh but they are. Just got one and it is so obvious that it's a must-have when I got it, it should've smacked me right in the forehead. Pliers of any kind will not work and you run the risk of upsetting the delicate balance or worse yet, breaking something. Don't delay like I did. Pick one up. OH, Weasol, Clockboy Hector and the rest were all correct on this one.

Been busy at work. I'll keep you posted.

Finally finished the Kundo clock after putting it aside while working on other clocks then going back to it inbetween, 

after bending a few suspension springs and clock running slow i did what someone suggested by putting a stronger spring in turning the adjuster all the way up to fast then gradually turn it towards slow it is running ok just a couple of minutes fast over 2 weeks i just need to find where i can get 2 screws for the guard that protects the suspension spring looked at different companies and ebay but no luck yet thanks everyone

      What are these Seitz B-Jewels?

      By Neverenoughwatches · Posted

      If frank says these bombè jewels are for balances and similar pivots then they are used cupped side facing the pivot and then capped i assume. In Nicklesilver's reply i guess that cup can also be reversed and used as an oil reservoir leaving the shoulder riding on a less frictioned domed surface. 🤷‍♂️ Hence the use of them on wheels closer to the escapement that have less torque requiring efforts to reduce friction and are also uncapped.

      Looks that way, if it had any amount of significant jewel count it would say so on the dial.    Looks that way, if it had any amount of significant jewel count it would say so on the dial.  Same answer as Mike regarding the dial, its often just a slapped on name of a retailer but i thought you were way above this understanding Pete ?

      Light naptha is what you need to be looking for. The carbon to hydrogen ratio is high with heavy naptha, it doesn't evaporate as well as light naptha and is prone to leaving more residue. Try tom's suggestion of the mirror test.

      I'm going to be setting up a decent little workshop here at home.

      Its a big item Michael and a lot that could go wrong with the process of getting it to its new location. I once helped install one of these units into a conservatory that i had built. It was big and bloody heavy and took six of us to get it in safely. If you have sliding doors and you need to remove the whole frame then that may or may not go well. But i would advise getting a professional in if you have little knowledge on the installation of them. The glazing of the doors could well be 6mm laminated glass which again will be heavy very heavy if the glazing units are big. The glass would also need to be set up and packed correctly to open the doors properly more so if they are unframed and the sliders are upvc. Seems a shame but if no one is biting and that may be due to having no warranty i guess the only takers might be someone that installs them for a living and knows how to repair. If its fibreglass just be careful, i sometimes have to cut fibreglass baths out and they are nasty to work with . Thick gloves are definitely recommended,  not fun picking out fibreglass spells two days later that have started to go septic. Good luck with it all matey.

      I don’t know anything about this product, however assuming you have it if you put a drop on a mirror or piece of glass lying flat on a table and leave it to evaporate if it leaves any sort of residue it is not really suitable for watch part cleaning.   Tom
