Timegrapher for Mechanical Watches - check the accuracy of your timepiece

Check the accuracy of your mechanical timepiece with this desk timegrapher. A must tool for any watchmaker, collector or enthusiast interested in checking the precision and accuracy of its mechanical wristwatch. Multiple measuring possibilities: rate deviation, amplitude, beat error of mechanical watches and diagram recording of the beat noise. 

International product, choose your plug type based on your country.

Product Specifications

- The frequency diagram of the watch can be displayed in the LCD screen.
- According to different watches, the instrument will automatically adjust optimal signal level during testing.
- The instrument will automatically calculate the rate, amplitude, beat error, and display them by data in real time.
- For the conventional beat, the instrument can automatically response; for the special beat, can manually select.
- The sampling period can selected by 2 seconds, 4 seconds, 6 seconds, 8 seconds, 10 seconds, 20 seconds, 30 seconds, 60 seconds, and the average of corresponding period will be regard as the precise value of the watch.
- Six kinds of testing position can be adjusted, and the simulation sound can be play in the speaker or mute
- Precise mechanical watches test instrument, it is used for multi-testing by watch manufacturers and watch technician.

Beat Numbers (Frequency Numbers)


The following beat numbers are selected by automatic selection mode: 12000/14400/18000/19800/21600/25200/28800/36000/43200
(If the tested beat is not in automatically selection, the instrument will display the closest beat number, but the test result is not correct. At this time, use the manual mode to select the relative beat.)

Manual selection

It can selected out the beat number that Automatic select can not identify and rare beat number.
The following beat are selected by Manual selection mode:

Lift Angle

The lift angle is 52° for many common movements, therefore the lift angle value of instrument for factory is set to 52°. This value is required to calculate the amplitude and must be selected according to the watch movement. The lift angle can be set to between 30°and 70°


The measuring period selectable:2s, 4s, 8s, 10s, 20s, 30s, 60s
Use to recalculate the average values of the test result.

- Measuring possibilities: Rate deviation, amplitude, beat error of mechanical watches and diagram recording of the beat noise.
- Frequency numbers: It can selected out the common beat number automatically, also can selected out the less common beat number by manual.
- Rate deviation measurement: the range of deviation is ± 999 sec / day, precision 1.0 sec/day.
- Amplitude measurement: Numerical display in degrees, resolution is 1°,measuring range: 100°to 360° (the lift angle can affect the amplitude, range: 30°to 70°.Under normal circumstances, the amplitude value do not exceed 360°.)
- Measuring period times for the average numerical results: 2s, 4s, 8s, 10s, 20s, 30s, 30s, 60s.
- Measuring of the Beat error(Frequency error): Numerical display in milliseconds. Resolution is 0.1 milliseconds; the measuring range is 0-9.9 ms.
- Lift Angle: the measuring range is 30 ° to 70 °, the factory set it to 52 °.
