Haute-Gamme watches often provide a view of the movement. Optical aspects are therefore of central importance when assessing the quality of individual components of a movement.

This also applies to watch screws and the head of the screw in particular. The perfect screw head is smooth and shiny like a mirror. The process leading to this result is called “poli bloqué”.

In recent years, we have worked with our customers to step-by-step industrialize and perfect this process.

In countless trials we have tested a wide range of polishing discs, polishing pastes, adhesives, cleaning media and machine settings in various combinations.

Today, we have the optimum process parameters for different types of screws and customer requirements and can manufacture them with process reliability.

"We know no compromise when it comes to quality. Together with our suppliers, we strive for perfection. With Laubscher, we were recently able to improve the process of poli bloqué."
