… This tray shows just a little collection of various parts that have to be produced before a movement can be assembled …

… I added a ball pen as a reference for the seize of the parts shown on the tray …

… some of these components are produced by wire erosion. The wire used in this process is as thin as hair …

… all these components of a movement were cut by a wire …

… some are really tiny …

… again the ball pen shows their real size …

… the precision these miniature parts are made of is astonishing …

… 1/100 millimeters is the standard …

… the wire is thin as a hair …

… gear wheels …

… cam wheels …

… and many more …

… this is the wire erosion machine …

… when once programed the machine works by it´s own …

… this department is in charge of producing all kind of normal and special components for the various calibres …

… a tray with parts that have been drilled and milled …

… to compare the size once again a ball pen beside …

… the production of a lever …

… the lever is stamped out a steel strip …

… to reduce the impact of the stamping on other machines four special vibration absorbing devices are used …

… after stamping the steel strip looks like this …

… to give the lever an exact defined form this stamp is used …

… a weight of some tons is applied …

… this is the machinery park with all the classical stamps together …

… and this is a look into the control of a more modern machine to produce small steel parts …

… again we encounter oil for cooling and cleaning …

… as already discovered for the main plate production also levers have to be adjusted in height …

… one by one the levers are aligned on this machine …

… then they are abraded and polished in one operation …

… the process has to be executed very carefully …

… to reduce friction jewels are pressed into the moving parts of the lever …

… I like the second magnifying glass of the lady on the photograph …
