I tried using the “Watch Accuracy Meter” app which allows you to measure the accuracy of your watch using just your smartphone|

As a tool for determining time,accuracy“It can be said that it is the lifeline of the watch. Just as there are no perfect things in this world,Wristwatches do not always identify one hour as one hour..

Even though technology has advanced and watches have become more accurate, they still lose or gain a few seconds a day.Especially if it is a mechanical watch..

Every watch collector wants to know the accuracy of his watches. There is a machine called a Timegrapher that can measure the accuracy of clocks, but it is expensive.

But with this appYou can measure with a certain degree of accuracy for free.That app…

The name of the application isSee the accuracy scale“. It can be downloaded for free on the Android play store.

This application isIt is very popularMany people use it. The measurement accuracy seems to be very good.

The reviews are also very good at 4.8 stars. This is worth a try.

So, I would like to try using this app, but before that, let me briefly tell you about the accuracy of the watch.

Mechanical watch isIt moves with the force of a spring that is trying to return.But if this force was not suppressed, it would not work like a clock. Therefore, in order to suppress that force and limit its movement,balance」「paternal uncle」「Escape wheel” exists.

The billet wheel moves due to the repeated movement of the balance wheel, which engages the teeth of the escape wheel and sets a stop to control the movement of the entire clock. For those who want to see detailed movements,Image from WikipediaPlease take a look.

When these are intertwined together,Tick ​​tock“It makes a sound. That's what you can hear if you put your ear close to the watch.Time scholars and others read this sound to measure accuracy..

The “click” sound is very small, so you have to pick up the faint sound. Smartphones are equipped with microphones that can pick up even the faintest sounds. That's why this app exists.

・Let's try to use it

Measurements are made by picking up sound with a microphone, so there is little noise.Let's do this in a quiet room.

It's easy to use, just place your watch as close to the microphone as possible.

You can also carry your smartphone between hours like this. The smartphone microphone is usually located at the bottom.

The remainder is “It starts“Just press the button!

Measurement begins. The application automatically calculates the vibration frequency, daily difference and rhythm error.

At this time as much as possibleBreathe calmlylet's do it. Try not to move too much and try not to cough as much as possible.

When the measurement is finished, it looks like this, “clock”Number of hitsIt can be seen.

First off, this is my favorite watch I've ever collected. Vibration frequency 21,600, daily difference +13 sec/day, error 1 millisecond…it's worse than I thought.

Well, this is how the lines are created by the “click sound”. The slope of this line allows us to see the difference in sunlight.

Next thisSoviet mechanical watch. The vibration frequency is 18000.

Well, it became a squishy line, and the daily difference was -43 seconds/day. On the human sideCauses irregular heartbeatOf all the watches I own, this is the oldest.

You can measure with your smartphone's microphone, but it's better to use earbuds!

Simply plug in the earbuds and point the microphone towards the bottom of the watch.

Well, there's not much difference in the results.

Well, this is an app that lets you measure the accuracy of your watch for free and easily.

If you use this, you may be able to adjust the accuracy while measuring.

So,See you again!
