Accuracy Boutique Edition User Guide

Step 1 – Download and Install the Accuracy App

Before getting started, make sure you have downloaded and installed the ONEOF Accuracy App for your smartphone or tablet from App Store or Google Play.

Step 2 – Connect the Device

Make sure you have the Accuracy App open and connect your smartphone or tablet to the Accuracy Boutique Edition sensor case using the provided connectors. Connecting the sensor will unlock the App.

Note: If you are plugging the sensor for the very first time, please make sure that an Internet connection is available.

Step 3 – Wind Up the Watch

If the watch is equipped with a screw-down system, unlock the crown.

Fully wind the watch by turning the crown clockwise.

Step 4 –  Place the Watch on the Sensor

Place the watch on the sensor. The crown should lay on the fine brushed square-like aluminum part.

Step 5 –  Measure the Watch

The App automatically detects the presence of the watch and starts its analyzing process.

After less than 30 seconds, the accuracy of the watch is displayed at the top of the screen.

Your next step depends on the results of the measurement.

Please note that the measurement will continue unless the watch is removed from the sensor.

If the measurement results show that the accuracy of the watch is stable and meets spec requirements: e.g. between -20 and +20 s/d – the watch is working correctly and does not require demagnetization.

Please note that slight fluctuations of a few seconds per day are common, especially if the watch is tested in several positions.

If the measurement results show fluctuations outside of specs when the watch is tested in several positions, you should go on to the demagnitization process.

Step 1 – Enable Demagnetize Mode

Touch the Demag button located at the top right of the screen.

The demagnetization process fires after 3 seconds (see the blue progress bar). A short high-frequency magnetic impulse is generated below the Accuracy Boutique Edition sensor.

This impulse instantly demagnetizes the hairspring of the watch.

Step 2 – Access Measurement results

When demagnetization is finished, the App automatically initializes a new analyzing process (see the white progress bar).

If magnetization of the movement was the real problem, the accuracy now stabilizes to a new value closer to spec requirements.

If the new accuracy is stable and within the specs, the watch is now fully demagnetized. The problem is solved.

If the new accuracy is stable and better than before demagnetizing, but results are still out of specs, the watch is now partly demagnetized. In this case please proceed to Step 3 of the demagnetization process.

Step 3 – Advanced Demagnetization

Hold the watch in another vertical position above the sensor and press Demag.

Repeat the process with four different vertical positions (press Demag each time).

Finally check accuracy. If the new accuracy is stable and within the specs, the watch is now fully demagnetized.
