Dedicated to guaranteeing the highest quality standards, Queloz SA has its own internal mechanical department, and in order to control the complete manufacturing process, all parts are cut and stamped in-house.


In addition, with an extensive range of equipment and machinery, the turning department provides the company with a large amount of flexibility in their work.


Queloz SA is furthermore at the forefront of technology in the field of milling, and the milling department is equipped with the latest generation five-axis milling device.


To ensure an impeccable surface, Queloz SA prepares surfaces by grinding to guarantee a perfect geometry of the work piece. In order to deliver an irreproachable outcome, each work piece is checked multiple times during and at the end of the production process. The experts in the “finishing” department furthermore master operations requiring special skills and delicacy such as manual circular graining.


Following the process of the “finishing”, the case pieces pass into the polishing workshop. Despite the use of machines that automate the process, polishing is one of the key steps in manufacturing watch cases, requiring the full attention of the specialist’s hands. With their expertise, our specialists work on making the cases shine from all angles and can achieve a perfect satin finish.


There is no reason to have the most outstanding technology and deliver the best products without a scrupulous control and a meticulous final assembly. Queloz strives to meet all of its customers’ needs by adjusting the equipment and visual inspection for each brand.
