This mechanical watch tester is a highly accurate test inst ent that allows watch manufacturers and watchrepair technicians to easily test mechanical watches.<br> It adopts flame-retardant housing with high flame-retardant properties, stability, and wear resistance, with long durability.<br> The 98x34mm LCD screen has a resolution of 192x64 pixels, and the data lines are<br> During testing, the inst ent automatically adjusts the optimal signal strength for different watches.<br> It can automatically calculate the values of deviation, amplitude, and beat error, and display the data in real-time.<br> The inst ent can automatically detect watches with regular beat and can manually select watches with special beat.<br> 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.<br> Measuring possibilities: rate deviation, amplitude, be-at error<br> Rate deviation measurement: the ranges of deviation is ±999 sec/day, accuracy is 1.0 sec/day<br> Amplitude measurement: numerical display in degrees, resolution is 1°, measuring ranges is 100° to 360°<br> Measuring for the be-at error (frequency error): numerical display in milliseconds. Resolution is 0.1 milliseconds; the measuring ranges is 0-9.9 ms<br> Measuring position: 1 to 6 positions<br> Sampling periods: 2/4/6/8/12/20/30/60s<br> Lift angle: 30° to 70°, default is 52°<br> Line length: 196 points<br> Please note that the physical slightly color difference or difference, does not affect the use, please do not mind, thank you!<br> Plug Type: US Plug, it applies to Canada, India, Mexico, Thailand, Taiwan, the United States, the Philippines and so on.<br> Plug Type :EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so on.<br> Voltage: AC100-240V<br> Colour:White/black<br> Material:Metal+Plastic<br> Package Contents:<br> 1 x Timegrapher<br> 1 x Power Cable<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the ite
