NOMOS Glashütte lathe

Only round-shaped workpieces are processed in lathes like this one, because the tools inside circle around the rotating caliber component. This is how pins, pillars, screws, wheels, pinions, or even the particularly challenging balance, the balance staff, and the corresponding plateau—one of the smallest parts that NOMOS Glashütte manufactures itself—are produced for NOMOS movements. Painstakingly precise: The strictest tolerances are two-thousandths of a millimeter, so 2 micrometers tolerated deviation from the specified dimension.
