Many problems-from rubbing hairsprings to knocking to problems in the gear train-reveal themselves in particular patterns of timing traces. When a watch runs well, it leaves two clean, parallel traces as it ticks merrily along. Without a timing machine, this is tedious and complicated. And we also need to read the rates at low amplitudes so we can find poise errors. We’ve talked about how we need an amplitude of at least 270 degrees in the horizontal positions and 220 degrees in the vertical positions.
In his great book on Illinois wrist watches, Fredric Friedberg mentions the factory’s “timing room,” where workers kept “hundreds of watches wound while they were being tested for accuracy” (p. Adjusting a watch to 6 positions was a drawn-out affair.Ī big factory would have a lot of watches sitting around, ticking merrily until the next visit to the adjuster. If necessary, the watch was adjusted again, wound, and left to sit for another day. The next day, the rate was noted, allowing a calculation of how slow or fast the watch ran in that position. After an adjustment, the watch was set to a standard time (or its deviation was noted) and then left in a position for a day. In the old days, watch adjusting could take weeks. If you don’t have a timing machine, you really need one.

Here is only the guide to install the Clock Tuner app on PC.Collectors of vintage watches tend to be fans of the old days and the old ways, but we’ll always take time-saving inventions when we can find them. We are not offering any downloads of Clock Tuner app. Everythings of Clock Tuner app like SS, logo and trademarks etc are not our property We are not claiming ownership of this app. ** You may provide sound sample by sending wav or mp3 file to What’s New on the Latest Edition Of Clock Tuner The bottom shows amplitude of sound wave recorded from micro phone.Ħ) are newer versions of the app being developed The size of bars in the upper graph should be almost the same. The ‘detected frequency’ should be red continuously.Ĥ) how do you calculate the pulse drift %Ībs(max detected frequency – min detected frequency) / detected frequency during 1 detection cycle.ĥ) what are the 2 graphs showing and what data are you using for the calculations Red means smaller drift during the measurement interval while grey means that measurement may have an error.ģ) the average frequency does not always calculate, it stays at NaN But small noise may measurement errors.Ģ) why does the detected frequency change between light grey, black and red If you increase the sensitive, you may measure hand watches. This will allow more environmental noises. If your clock sound is loud you may reduce sensitivity. It determines sound amplitude threshold for detecting clock sound.

Most pendulum clock: Target frequency: 1 or 2 Hz, Sample duration: 5 or 10 Sec, Sensitivity: mediumġ) in the settings there is a sensitivity option with a high, medium, low and 3 manual settings, can you explain how this changes the results Rolex or mechanical watch: Target frequency: 4 or 5Hz, Sample duration: 2Sec, Sensitivity: manual 50 The app will work as Premium during 30 min. ** Please test the app with your watch before you purchase ‘Premium’ upgrade. ** Frequency display requires ‘Premium’ upgrade. ** Basic version display wave graph and pulse interval histogram. ** Recommend to plug a microphone into phone and attach the microphone to the back of your watch. It will display time error per day as well. This app is to measure the BPH(Beats per hour) of mechanical watches.
