In an experimental situation the hardness of the uppermost layer of material in the contact may not be known with any certainty, consequently, the ratio is more useful; this is known as the dimensional wear coefficient or the specific wear rate. This is usually quoted in units of mm 3 N −1 m −1. [5]

Whereas "running any functional object will result in wear and handling, which contributes to the degradation of the parts. Replacing the inner workings of a clock still requires handling, which could potentially damage the clock.
