NO.3000 is a precise mechanical watch testing instrument, it is used for multiple tests by watch manufacturers and watchmaking technicians. -The frequency diagram of the watch can be displayed on the LCD screen. According to different watches, the instrument automatically adjusts the optimal signal level during the test. -Automatically calculate the rate, amplitude, beat error and display them by data in real time. -The instrument can automatically adjust the signal strength according to the different watch.
