Witschi watch expert manual


Recommended Posts

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

    • although not in this case.  It was the Lugano Convention and its deficiencies that allowed a Swiss court decision in the first place.  This isnt really a Brexit issue at all.  A decision that affects both the EU and the UK should never have been heard in Switzerland. I bet the authorised service centres in the UK are pretty pleased.  It's a massive shame, though; I believe watch owners should be able to choose to have their watch serviced by whoever they trust.
    • Hi guys I think that old hippy is correct, it opens the gates for china to manufacture aftermarket spare parts. considering that they already do work on behalf of the Swiss I guess this decision gives the a little more legitimacy to tool up and I am sure they will take advantage of the situation either with or without the blessing of the Swiss watch industry  Having read about the protectionist machinations of the Swiss in the history of Europe they were the only ones to get fat at everybody else’s expense. I think the outcome could have been guessed at but ,  fair play to Cousins UK for standing up to them.  Now the question,  will everybody boycott Swiss watches and Swatch, no way they will still fill their coffers.  Me I stick with the Japanese once renowned for cheap shitty watches who came good through industrial effort and don’t for get the Russians that most dismiss as low grade crap. Wouldn’t buy a swatch product ever how about you all.? a
    • Hold the crown when in winding position, move the click away from the crown wheel, and then while holding the crown let it slowly unwind. I recollect that you must remove the automatic device bridge first, but maybe I'm wrong. You can first try without removing the automatic device bridge.
    • nevenbekriev- You nailed it with your description of me and my reaction when the clock started ticking again. I am a newbie.  I love the sound and idea of mechanical clocks but the idea of owning one and trying to keep them running has never appealed to me. My wife bought this one and an antique German wall clock.  When I looked into having someone repair them for me, the universal response was "it's really expensive to work on them, you should just replace the movement". So, I had nothing to lose, I started researching them and opened them up. The wife is happy because she hears the sound of the clocks again. But I have gone down the "accuracy" rabbit hole. In the vertical position, the balance wheel was not floating. It was sitting on the bottom of the frame. I adjusted the lower spring collet and got it floating. It easily passed the 270 degree 3 to 5 minute oscillation test. It took 8 minutes for the wheel to completely stop moving.  I put it the unit back in the movement and checked the safety pin. It does not touch the safety roller anywhere in +/-270 degrees rotation from neutral position. But the amplitude of the rotation with the spring fully wound is weak based on what you are saying. It rotates +/-90 degrees from the neutral position.  No, I did not take the movement completely apart.  That seemed way outside my skill set at the time. There is a reason I became an electrical engineer and not a mechanical engineer. I am much more comfortable with moving electrons than tiny moving metal parts. Will I do it in the long run? Anything can happen. I don't seem to be able to let it go.
