For anyone that's curious about what witschi timing machines are like the first link has demonstrations you can download. Seating kinda play with the buttons and see what things are supposed to look like.

Then there's actually four generations of the watch expert. First three generations the case looks identical except color. Enhancements added to each generation improving things. Third generation has a backlit screen which hopefully makes it much easier to see. The second-generation screen is a really shiny and reflects everything like overhead lights. Fourth-generation the machine below is basically an entirely new machine.

So first link demonstrations and the Witschi Training Course Which really is good for anyone with a timing machine.

Witschi timing machines are interesting versus the Chinese. If things are perceived to be out of range the witschi machine will give a variety of error messages and then refused to do anything. If it's a Chinese machine it typically will not give an error and will try to show something whether it's right or not.

Then it be helpful to know which watch are you timing and a picture of the display in manual mode when it's running as you perceive correctly.

In auto mode the machine will attempt to figure out what frequency watch you have. In auto mode it has a limited number of frequencies it will look at basically the standard. If it perceives its outside of that then you get the error message. This is where in manual mode you select like 18,000 it now knows what it's trying to time and it will time it providing its within the range of what it can do. Simplistically it's telling you it's having a problem that needs help which means there's probably some issue with the watch perhaps.

This is where it be nice to have something this machine does not have a oscilloscope. But you can also listen to it and see if it sounds right. Because anything that sounds incorrect might be upsetting the machine anyway.

Then sometimes If things get really bad you can go to rate only it won't display amplitude or beat But usually that solves the problem if things are really having issues and you still want to display something.

Then I'm attaching the PDF of the users manual

      Help - London Elliott Mantle Clock Night Silence

      By MapleWood · Posted

      I've managed to adjust it. I'm going to try and explain it as well as I can with my limited horology knowledge but I hope it helps someone in the future. There is a cam to the right of the front plate as shown in the picture. As the clock ticks along, the pin indicated in the gear comes around and slots into one of the silencer cam gaps, turning the cam. The pin completes a full rotation in 2 hours. To adjust the cam to start at the right time set the clock to just before 7. I did 6:45. Then I turned the silencer cam anticlockwise, which spins freely, until it pushed the silencer lever up and was placed just before the drop. Just before the 7AM indicated in the picture. All I then had to do was progress the hands to 7-7:15which made the pin slot into the silencer cam gap and turn the cam so the lever comes down again, unsilencing the clock. That was it. If anyone comes across this issue again I'd be happy to assist. Thanks again to everyone that helped.

      Epilame / Fixodrop

      By Waggy · Posted

      Now I'm completely confused, it would appear that the epilame  is oleophobic  as @Marc states: This oleophobic  behavior can be seen as beading of the droplet (as above) which stops the oil spreading which is supported by what we observe on treated/untreated cap stones (for example), but as @VWatchie states this should make the drops more mobile, and not less mobile which is the opposite of what we want. In fact this beading and high mobility are desirable properties in things like smart phone covers, see below.  I am fairly sure that epilame doesn't make the droplets more mobile, so maybe its a strange coating with dual properties that are both oleophobic and cohesive/adhesive resulting in low mobility?? This may explain the high price??

      The description there is exactly how it's done, and it's very well written!

      What is the correct way to lubricate clock mainsprings?

      By HectorLooi · Posted

      Would it be correct to say that the stronger the mainspring, the thicker the oil should be? So for a fusee mainspring, should a thick grease be used?

      Vintage pocket watches from e-bay (winding stems needed)

      By mikepilk · Posted

      I started on pocket watches as they are easier to work on than wristwatches. Many had gold cases, which is why there are so many movements for sale. I was always on the look out for cases, for as Nickelsilver says,  a 16s movement will fit any 16s case* (with tweaks to the stem). I also started hand winding mainsprings, before I had winders. It can be done without damage, but it's quite hard on the fingers.  But you can make homemade winders, see here      * some movements, eg "railroad grade", have a setting lever on the edge of the  dial at about the 1 -2 o'clock, so need a special case.
