This document concerns whole watches, in which all or some of the components of the external parts are made of hard material, with the exception of watch glasses.
It applies to all elements made in massive material whose hardness is greater than or equal to 1 200 Vickers.
It describes the performance in terms of resistance to mechanical and thermal shocks, to corrosion, to scratches, to sunlight exposure and also to the wear of its components.
