This Watch timing machine model is NO.1000, known as a precise mechanical watches tester
This watch tester calculates rate, amplitude, and beat error using readings from the microphone stand automatically. Very easy to use for mechanical watches
The Timegrapher is with LCD screen displayed. The LCD screen shows the readings in real time with 2 dotted lines, and it automatically adjust optimal signal level during testing for different watches.
There are 6 kinds of testing position adjustable. Amplitude level: 275 ~315; Rate Deviation Range: ±999 s/d with precision ± 1 s/d'
The timegrapher sampling period can selected by 2 , 4 , 6 , 8 , 10, 20, 30 , 60 seconds, and the average of corresponding period will be considered as the watch precise value.
