    Thank you very much for your answer B52. And for the details that enrich our trials. I agree with you, it is necessary that you possess skills in the field of electronics and mechanics in order to obtain acceptable results. I have a question about the Junghas Cal 75 movement. Is it 18,000 BPH? Does it run within the acceptable ranges, that is to say, its error to march does not exceed more than 60 seconds? About the 90-year vintage movement, is it a bph that can recognize TG? regards Guido. Here example sund. Omega Seamaster De Ville +18seg aprox. https://mega.nz/#!uCIGzSTZ!OosG2VcTsj7uA8JDCczusvRjFTxIzMk5IVHAzD3UdCk

    Hello B52. Thank you very much for sharing your experiences. We will have to test your project. However, in our limited knowledge and experience we have seen that what has worked best is the piezo electric disk. We know that it has its weaknesses, but even so it can be efficient. One of the reasons why we see that it is so, is that most time machines, use the principle of the vibration sensor instead of the microphone. For the same reasons that you have exposed: The background noise. We would like you to put us a piece of recording in wav or mp3 to check your results. Congratulations. And thanks for getting in touch with other elements that could be used. I would like to know if there is a pre-amplifier with a similar presentation to which you show us.

    Excellent document. Although you comment that it does not seem to be aesthetically good, for me it is. It's the best I've seen.

    Was expected. The sensor that we are looking forward to be tested is the one that JohnR725 has indicated to us. I am not surprised at all in your statement. Do not worry ... we've also lost time and money on devices like that. https://uk.rs-online.com/web/p/vibration-sensors/0285784/

    The positions that produce the greatest amplitudes are the horizontal ones for the balance wheel. The values should be as close as possible, that would indicate that there is no damage or anomaly in the pivots and bearings of the balance wheel axle or something in the pallets, roller ratio.Here I can guess that something happened. the watch received full wind. The main spring is completely wound up and that generates this bounce. (Rebanking.)

    How a good signal makes a difference.

    Thank you very much Frank, very good explanation. And I agree. TMCP is an excellent software. Very efficient clean and simple. It is one of my favorites when some of the others fail. I would like to know how much the full version costs. I do not think I'm in conditions because of economics. But maybe some of the classmates are interested. It seems to me a very good option. Regards Guido

    The movement of the clocks generates three readings that help the watchmakers to determine the condition or state of a watch. These are the Readings: Rate, Amplitude, and Beat Error. Here we see the graph produced the "Timing Machime", We will focus on the amplitude. The amplitude refers to the rotation made by the balance wheel from its resting point (theoretically stopped and without wind) to any of its extremes. Be levógiro or dextrógiro. This must be between 300 degrees. The position of the watch, the cleaning, the quality of its lubrication and condition of the machine, will affect this result. In the case of the graph here, made with Watch-O-Scope, it indicates that they are 202 degrees. To obtain this result it is necessary to enter a value to the time machine. It is called elevation angle (lift Angle) value that is found in tables prepared by manufacturers or made by people from different documents. There you can see the Lift Angle value in the graph 41 deg. After watching the video in normal playback is difficult to see how accurately rotates the balance wheel. By the way, I made a point of reference aligned with the ruby ellipse or impulse pin. And in the reproduction in slow motion, then yes you can see that the balance wheel turns a little more than half a turn that would be 180 degrees. And it is what the time machine tells us. 202 degrees

    The key part of the Timetrax sensor is not that the box isolates the sound. Rather, all the tension is not received by the sensor, but by the pin. Key is that the sensor itself, does not receive tension flexion pressure or torsion ....

    First of all, what a beauty the graphic presentation of the Wistchi! And your options. I'm going to say a little. In the first instance, our tool should be as sharp as possible. That will make things easier if our ability is too. We can not expect consistent results if any of these things are not well-honed. Something over which we have no control is how the watches we repair will reach our hands. And for that, I'll cite an example I had last week. I got a Junghas kitchen wall clock. from about 1960. It is a "floating" type Spiral balance wheel watch. But this one has the peculiarity that is suspended magnetically. Two toroids or magnet donuts in equal poles are responsible for suspending the balance wheel. The clock was stopped, so we could not do a "before" reading. After a thorough work cleaning and correcting wear problems, when making the measurements with the time machine, NO COULD DETECT IT. None detected the beat. It was only Biburo who helped me. In its beat detection mode. What was the matter? the clock was gaining 25 minutes a day. That already co-operates with any machine. So, what are the machines for? To help us, but for that we have to know them. Or choose among those that we have to help us better. On the other hand, neither WOS, much less tg, had among their list of beats, 9000 bph. or 2.5 bps. So I went to sleep or at least to the bed thinking about why the beat could not be detected. The easiest thing would have been to place hands and see how much time went ahead for at least 12 hours. Then I was thinking ... in bed ... and the next day I had the solution: it was ridiculously simple. The regulator was too out of range. Although the index indicated 0, the regulator was not at the correct point. Here is del Clock: Clock Junghans. Clock Junghans final correction

    Here is an example of what WOS accomplishes. It's the audio track that you hung on your Ingersol. What other programs do is that they apply filters or algorithms that choose the best of the waveform. and they present it to you. It's what I did here. To correct the rate I modified the WOS calibration factor to a value of 242 seconds +. That explains why the clock is now marching near the right, which is false of course. Do not forget the filtering factors that you can apply in WOS

    I think it's an unfair prosecution of WOS. It's a bad microphone. A poorly preamplified signal, The clock is far outside the Rate. I have my opinion about WOS. In the programs that I know and that are missing 2 in the list that the partner placed, Biburo and eTimer, and the others, I place WOS in second place. I think that to make an appropriate qualification to the program it is necessary to have a pre-amplifier and a good microphone. (reasonably.) In the image below I also think that you can choose the value that I enclose in a yellow circle and the others I indicate in red. Regulate the clock so that it has an offset of - + 20 seconds, or less. With all the respect that friends deserve.
