Mechanical Watch Calibrator is a high precise instrument specially designed for testing and calibrating mechanical watches. It can measure various performance parameters of mechanical watches, such as rate deviation, amplitude, beat frequency error and so on. Through the measurement and analysis of these parameters, it can accurately judge the performance and status of the mechanical watch, so as to carry out precise adjustment and calibration to ensure the accuracy and stability of the mechanical watch. Features: This mechanical watch tester is a highly accurate test instrument that allows watch manufacturers and watchrepair technicians to easily test mechanical watches. It adopts PC flame-retardant housing with high flame-retardant properties, stability, and wear resistance, with long durability. The 98*34mm LCD screen has a resolution of 192*64 pixels, and the data lines are clearly visible. The entire frequency diagram of the watch can be displayed on the LCD screen. During testing, the instrument automatically adjusts the optimal signal strength for different watches. It can automatically calculate the values of deviation, amplitude, and beat error, and display the data in real-time. The instrument can automatically detect watches with regular beat and can manually select watches with special beat. 2s, 4s, 6s, 8s, 10s, 20s, 30s, 60s test periods can be selected and the average value of the watch time of the selected period can be calculated. Adjustable for 6 test orientations, with or without analogue sound can be set during the test.
