I could quite clearly determine the difference in regulation between orientations- and confirmed my suspicions that my ETA2824-2 movement would speed up during the day by 2-4seconds per day but that could be negated by leaving it crown-up during the night.Īs far as the graph goes- apart from the dependency on a quiet environment, it looked about right for a newish clean, well regulated swiss movement. I've also had good results using an external microphone and using an elastic band to fasten the microphone to the caseback which also enables easily changing the orientation of the watch- crown up, down, 12 up, down etc. Some of the best results are obtained by using the Apple earphones with integrated microphone and resting the watch crown on the microphone- there seems to be good mechanical/accoustic coupling between the movement and the crown- possily because the winding stem seals mechanically isolate the tiny vibrations to the world outside the case. Best results are taking the measurements in a completely quiet environment and covering the watch and microphone with a folded towel or such to dampen external noise. Any noise shows as a disturbance to the line graph which could be misinterpreted as an issue with the movement. Getting a good audio feed into the iPhone/iPad is critical.

There's a youtube clip of the software in use with an iPad at The slope of the lines illustrates a gain or loss of time- and a separate reading shows the actual estimate error in seconds per day.

It displays the graph of fork noises over a timebase of 30 seconds (the timebase is different to whether you are using an iPhone or iPad due to the different screen real estate)- from which you can visualise from the cleanliness of the two lines an understanding of the health of the escapement.

The app determines the movement's bph (28800 for most of my watches) and gives an estimate of amplitude (the slew angle the balance swings over) and of the phase error (the variance between successive ticks and tocks in milliseconds). Setting the sensitivity and adjusting the position of the microphone is helped by the displays of counted 'ticks' and that same display turns red when it receives data samples (noises) which it thinks are erroneous and discards those so as not to throw the results. You enter the lift angle for your movement (50-53 degrees usually) and can manually set the sensitivity/gain of the microphone input to optimise the cleanliness of the audio recording. The app 'listens' to the watch heartbeat and provides diagnostic information. look-Įssentially you use an external microphone mechanically coupled to the watch. There are a handful of watch regulation apps out there but this caught my eye because of the time variance graph display in the same vein as a hardware timegrapher. I would encourage the developers to revise their instructions to specify use of the earbud microphone only, and not the built in microphone.I've recently been playing with an iOS app called 'Timegrapher- watch Tuner'. Also, keep in mind that the earpieces of the earbuds emit a strong enough field to affect a compass needle, so keep the earpieces away when using the microphone. An iPhone appears to be a bit safer since the speakers and microphone are on opposite sides of the device, but caution would still be wise. Although microphones do not create strong magnetic fields, speakers do create strong fields, and the speakers on an iPad are directly adjacent to the built in microphone.

I also purchased an earbud with a microphone, and am having more success obtaining reasonably accurate results, keeping in mind that this is an inexpensive hobbyists tool rather than a professional tool costing hundreds of dollars. After purchasing a demagnetizer, my watch now appears to be back to normal. Even worse, when using the built in microphone of my iPad, it magnetized my watch, causing a watch that typically runs at -1.1 sec./day to gain about 40 seconds in a day, and then to run about 5 sec./day slow.

Initially, I had far more failures than successes in trying to obtain good data from this app.
