… this photograph shows the machine just pressing one jewels into a bridge …
Now let us discover how the jewels are pressed in the main plate and other components to later reduce the friction in the movement.

… Skilled hands trim the main plate by removing burrs from it …… done or still to do …… a team of four women is in charge of trimming the main plates …… these are traditional tools to press the jewels into various components…… the work is mostly done by women …… since some of the components are pretty tiny you need the right magnifying glass …… first the lever is placed on the tool and then the jewel is pressed in with an exactly defined force …… the close-up shows the red pressed in jewel at the left side …… special tools can be found here …… another component is first placed on the tool and then the jewel is pressed in it …… this is the future: modern CNC-machines take over the work. The machine first picks up the jewels and then presses them with the exact defined force into the component or the main-plate…… this photograph shows the machine just pressing one jewels into a bridge …… at the left side are the trays for the jewels, in the middle you see the bridge and in front a try with more bridges that have to be machined …… the Swiss machine is produced by CHMicrotech …
… for a better understanding what is going on and to discover the original “sound” of this CNC-machine the movie will show some details …
… the lady assembles the barrels …… at Zenith each barrel is controlled and tested …… it is essential that the barrel delivers the right amount of energy to the movement…… an overview of this department at zenith in Le Locle…
