In the assembly process, all parts undergo a visual and technical check. If parts are not perfect, they will not be used and replaced by parts which do. The following final quality check is done in two locations. The first one is done in the atelier in Pforzheim. The watches undergo a visual test, a water resistance check and a technical check on the movement.

Each watch will leave the atelier with a unique print-out of the performance its very own movement. This is done by a very often used machine in watchmaking, a Witschi tester. Then the watches go to the main location in Switzerland. There they are checked overall one more time added to the packages ready to leave to destinations all over the world.
