Model: M-1000
✅Easy to use for mechanical watch collection. This watch tester automatically calculates rate, amplitude, and beat error using readings from the microphone stand.
✅LCD screen displayed. According to different watches, the instrument will automatically adjust optimal signal level during testing. - The LCD screen shows the readings in real time with 2 dotted lines moving across the screen to provide a visual representation of the “tic tock” from your watch
6 kinds of testing position can be adjusted. Amplitude level is between 275 and 315; Rate Deviation Range: ±999 s/d with precision ± 1 s/d'

M-1900 ：This No.1900 timegrapher is a precise mechanical watches test instrument, it is used for multi-testing by watch manufacturers and watch technician.

Features:

✅The frequency diagram of the watch can be displayed on the LCD screen;

✅According to different watches, the instrument will automatically adjust the optimal signal level during the test;

✅The instrument will automatically calculate the rate deviation, amplitude, be-at error, and display them by the data in real time; select "±99.9s/d" at item rate ranges for result display, 

which can make the accuracy of rate deviation up to 0.1s/d;

✅For the conventional be-at, the instrument can automatically respond; for the special be-at, can manually select;

✅The sampling period can be selected by 2 seconds, 4 seconds, 6 seconds, 8 seconds, 12 seconds, 20 seconds, 30 seconds, 60 seconds, 

and the average value of corresponding period will be regarded as the precise value of the watch;

✅Six kinds of testing positions can be adjusted, and the simulation sound can be played in the speaker or mute;

Specifications:

Color: grey+black;

Measuring possibilities: rate deviation, amplitude, be-at error of mechanical watches and diagram recording of the be-at noise;

Rate deviation measurement: How fast/slow the watch runs in seconds per day.If it is wildly out of these ranges, you should bring it to a watchmaker to get it checked out. 

Excellent -  +/- 7 s/d, Acceptable - +/- 20 s/d;

Measuring ranges: ±999s/d or ±99.9s/d;

Resolution: 1.0s/d or 0.1s/d;

Amplitude measurement:It’s the amount of rotation in the swing of the balance wheel; A healthy movement should, at full wound, have a high amplitude; 

A low amplitude generally indicates problems that needs to be fixed prior to regulation, like obstruction due to foreign elements, oil drying up, etc, but anything above 250 degrees can still be considered healthy amplitude;

Measuring ranges: 100°~360°;

Resolution: 1°;

Measuring of the be-at error:It’s the time difference between the “tick” and the “tock”.

Excellent : 0.0 - 0.5 milliseconds, Acceptable : 0.6 - 1 milliseconds;

Measuring ranges: 0.0~9.9 ms;

Resolution: 0.1 milliseconds;

Lift angle: This should be set manually prior to using the timegrapher, the reason you need to input this into the Timegrapher is so that you can calculate the amplitude. 

And you can find the exact number from the official specs of a movement. Most modern watches have a lift angle of 52 degrees;

Measuring ranges: 30°~70°;

Default value: 52°;

Measure positions: 1-6 positions;

Line length: 480 points;

Measuring times periods: 2/4/6/8/12/20/30/60 seconds;

Working environment: 10℃~40℃;

Relative humidity: 0~80% RH;
