Solutions for watchmaking quality control

35 years of experience in developing systems for the watchmaking industry
Watchmaking quality control
Solutions based on extensive experience in the watchmaking industry

Watchmaking is a sector where the quality of finished products is an essential element of brand image. Watch components and sub-assemblies require particularly high levels of precision, reliability, and finish.

Watchmaking quality control thus combines dimensional, functional, and aesthetic checks. Measuring the daily rate and the anchor's depth of penetration are examples of controls specific to watchmaking.

Drawing on its extensive experience in developing solutions for the watchmaking industry, qmt offers a range of standard products and customized solutions based on optical and acoustic technologies, as well as intelligent software. We define the optimal solution to meet each client's specific needs, based on a proven standard that can be personalized.

The strengths of a collaboration with qmt
  • A very good knowledge of the specificities of watchmaking
  • Products developed specifically for watchmaking with the ability to be customized
  • Aesthetic control solutions integrating artificial intelligence
  • Our ability to create micro-mechanisms for manipulating parts

Mastery of watchmaking specifics
35 years of experience

This experience allows us to master the technical specificities of the sector: measuring rate, checking escapements, verifying lubrication, and performing aesthetic inspections of ultra-high-precision components. Our solutions support manufacturers and their industrial partners in meeting their requirements for quality, reliability, and performance.

Engagement in the ecosystem
qmt is active in technical associations

Our participation in organizations such as the Swiss Society of Chronometry (SSC) and the Swiss Association for Watchmaking Research (ASRH) allows us to stay closely abreast of technological developments in the sector and to contribute to the development of measurement and control methods applied to watchmaking.

Privacy and cybersecurity
An organization and software guaranteeing security

Data protection and project confidentiality are essential in industrial collaborations. QMT has implemented a secure IT architecture and an information system security policy to protect technical data and communications with its clients.

Oscillating mass control device for MONNIN SA
Beat measurement and situation
To guarantee the quality and reliability of oscillating weights, QMT developed custom equipment for Monnin that allows for precise product characterization before final assembly of the oscillating weight into the movement. Measurements are performed using telecentric vision. The measurement reference is taken from an image on a component of the equipment fixture. This component is rectified and measured to compensate for any potential measurement error.

qmtocr for the watchmaking industry
Reading the numbers engraved on the movement and case components
To ensure traceability in production, the serial numbers of the movements and boxes must be read. The qmtocr is particularly well-suited for this application.
The ability to read numbers without programming on a 50mm x 50mm surface allows for very easy integration into existing processes. Reliable reading of small numbers on complex surfaces ensures robustness.
Connectivity and customization capabilities enable optimal management of both input (product information) and output (label printing, backup, etc.) data. It is also possible to integrate automatic checks to identify any inconsistencies and duplicates.

Roadway lantern height control device
A tailor-made solution
The wheel is a watch movement component to which the minute hand is attached. It is a cylindrical tube with teeth cut into its base from a larger diameter, and two opposing bosses are created to allow for the lantern pinion. This part is essential for timekeeping and setting. QMT has developed a custom-made device for dimensional control of wheel wheels, particularly the height of the bosses (lantern pinion height). To measure all the characteristics, the part is rotated with synchronized image acquisition.

The qmtprojector-cadran controls the quality of the MoonSwatch
A standard product customized to meet specific needs
The QMT projector-dial is a piece of equipment dedicated to the quality control of watch dials. It is used by many manufacturers and dial makers. The RTS report from January 24, 2023, showing the MoonSwatch production line, focused for a few seconds on the quality control performed with a watch projector (the former name for the QMT projector-dial).
The qmtsubface control functions are dedicated to this type of application; they integrate Artificial Intelligence to have a learning capacity.

Watchmaking tap measurement
According to NIHS standards with the QMT projector-100
The quality of micro-threads is a requirement in the watchmaking industry; checking the tool before the operation is the only guarantee of optimal results. The QMTProjector-100, a high-precision measuring instrument, is perfectly suited for checking watch taps. This measuring device benefits from QMTMesure-Base software for high-precision dimensional measurement (without any programming required).
