Compatible with almost all mechanical watches, it can calibrate coaxial watches. It is a watch calibration tool that is very worth having for amateur watchmakers, watchmakers and watch technicians. The Chronograph No.1900 is a precision mechanical watch tester that automatically adjusts the optimal signal level according to different watches during the test. The chronograph will be an excellent addition to your watchmaking table and a useful tool to determine the operating condition of your watch. The sampling period of our watch tester can be selected as 2, 4, 6, 8, 12, 20, 30, 60 seconds, and the average value of the corresponding period will be regarded as the accurate value of the watch. The frequency graph of the watch can be displayed on the LCD screen. The mechanical watch calibration tool has six adjustable test positions, and the simulated sound can be played or muted in the speaker. The amplitude level is between 100 and 360; the rate deviation range: ±999 s/d, the accuracy is 1 s/d'. The chronograph tester will automatically calculate the rate, amplitude, beat error, and display the data in real time. And there are 2 dotted lines moving to provide a visual display of "ticking" on the watch.
