Made in Glashütte: 7.9. Hardness testing

The hardness of a material is important for many aspects of watchmaking. It influences the function of the component, how it wears down, and thus how long it can be used—as well as the friction between two components, the corrosion resistance, elasticity, and many other properties. Measuring hardness is a crucial aspect of quality assurance, not least because hardness cannot be assessed visually. nomos-glashuette.com #nomos #nomosglashuette #madeinglashuette
