The TGB series calibration instrument is a calibration tool that works with Windows computers.
He can measure the watch's daily difference, polarization, swing, frequency, waveform and other professional data in real time
Through these data, you can judge the condition of your watch and use it as a basis for maintenance.

In addition, you can also open the back cover of the watch and adjust the balance spring to make the watch more accurate. No longer have to worry about blindly adjusting the balance spring.
With the meter calibration device, you can calibrate your watch at any time, saving you the cost of multiple meter adjustments. The PC software is very simple, and it will work automatically when you open it. The PC software and user manual are provided free of charge after purchase. Android software (the software fee is paid to the software producer) requires additional use (the accuracy is not as good as the PC side) for portable use when going out.
