Hardness is a measure of the resistance of a material to scratching, abrasion, or other forms of physical damage. The hardness of a watch is determined by the material used in its construction and the level of craftsmanship that goes into its making. Hardness is important to watchmakers, because it helps ensure the durability of the watch and its components. High hardness materials are more resistant to scratches and other damage, which helps to keep the watch looking its best for longer. Hardness also helps protect the watch from shock and other environmental factors.
