    Servicing My First Chronograph!

    "Try using a vacuum cleaner with ladies tights stretched over the end of the hose!" I don't know about this. I tried it but my wife was annoyed and got a cramp while I pulled the tights away from her leg and used the vacuum. :)

    Sorry for the extremely bad picture, with bad lights the mobile phone just does not cut it... meanwhile I already polished the glass so it looks way much better...

    I had a yearning for a Chromo so I bought an Omega Speedy. It was impossible to read the sub dials so I sold it. I've regretted it ever since and especially now that I've got myself a pair of bifocals and can see properly. :pulling-hair-out:

    If you must read with loupes,try using the same magnification in each eye! oO Wis is wls! :-)

    Timegraph Doubt

    When using a timing machine to diagnose watch problems there is several things you have to remember. For incoming watches the timing machine may possibly give you a clue as to what the problem is or it may give you incorrect information. Timing machine relies upon listening to the sound of the ticking watch. It has to pick up the signal clear and cleanly to display all the things correctly and do all the calculations like for amplitude. So for incoming watches that are need servicing just have to accept that the results will be different and you can’t rely 100% on exact diagnostics. Then if you are doing diagnostics with a timing machine you should do it correctly and time in more than one position. So dial-up, dial down at least one pendant/crown position preferably four positions. This way can pickup bad pivots on both ends of the balance wheel not just one and other things can show up in the pendant positions. So when I look at your timing machine results the amplitude seems extremely outstanding the waveform does not. So I suspect visually when you look at the balance wheel amplitude it’s going to match the waveform specifically it’s going to look really bad. Your first picture interesting in that you appear to have a repeatable pattern? Some faults in a watch will repeat themselves if you can determine the rate at which it repeats you can figure out where it is. This is sometimes an issue with the modern liquid crystal display as we don’t have enough room to look for patterns. This is where timing machines that used paper tape beat out liquid crystal displays as they have a infinite length display. But some modern timing machines will do a different kind of the time plot that will also let you look for things like this.
