QMTProTime
For measuring daytime walking
Range of day rate measurement equipment from completed watches and movements
The measurement is based on taking two images of the product spaced in time which are temporally referenced thanks to a precision time base. The time indicated by the watch or the two-state movement is given by the position of the hands which is defined in the high resolution image. The rate can thus be calculated thanks to the difference between the deviation in the state of the watch and the deviation in time defined by the time base.
The QMTTimeProcessing algorithm takes into account discontinuous displays (hand jump for example) and display desynchronizations. The new laboratory mode allows high-speed and continuous measurement of the position of the indicators in order to allow advanced analysis of the operation of the movement.
- The measured average rate corresponds perfectly to the customer's perception, on finished watches and movements of all types.
- QMTTimeProcessing for detecting discontinuous hand advance and correcting display desynchronization.
- A laboratory mode for analyzing the operation of the watch mechanism (optional).

QMTProtime technologies
To ensure the ability to measure accurate daytime steps, the QMTProTiem incorporates the following technologies
Digital cameras of 2,500 x 2,000 pixels (5MPixels) with an acquisition speed of 90Hz. The camera is electrically synchronized with the time base in order to be able to timestamp the images with guaranteed precision
In order to be able to measure movements in caps and watch heads, versatile double lighting has been integrated. It allows for optimal image quality and versatility
qmt has developed a specific time base for the QMTProTime. It offers relative time measurement with a sufficient level of precision
The computer system is integrated into the equipment in order to have a completely integrated solution that does not require computers
The QMTTimeProcessing algorithm takes into account discontinuous displays (hand jump for example) and display desynchronizations. The new laboratory mode allows high-speed and continuous measurement of the position of the indicators in order to allow advanced analysis of the operation of the movement
QMTProTime applications
The measurement is based on taking two images of the product spaced in time which are temporally referenced thanks to a precision time base. The time indicated by the watch or the two-state movement is given by the position of the hands which is defined in the high resolution image. The rate can thus be calculated using the difference between the deviation in the state of the watch and the deviation in time defined by the time base
This mode allows high-speed reading of the position of all the indicators. This function allows an advanced analysis of the operation of the movement to detect possible failures
QMTProTime software
The software for high-precision step measurement with assisted programming
The control program is carried out using an intuitive interface including program templates, standard control sequences and functions that automatically detect the characteristics of the part and propose them. The operator can thus select the controls and define the tolerances, the control program is thus created automatically. The possibility is also offered to add functions available in the QMTStore or to have a personalized function developed through the Fit For You program.

fit for you program (FFY)
Qualimatest products can be customized both from a hardware and software point of view. The first level of software customization is the addition of additional functions (available under QMTStore) or the development of a custom function
On the basis of Qualimatest products, it is proposed the realization of labeled product in the name of our customers who can be private or marketed by themselves
“More than 100 systems are produced each year for a large number of customers”
