Instrmnt K-Series watches are directly influenced by the science of materiality and colour theory. Made from nitrile rubber, a material created through a process of polymerisation that transforms molecular particles into more advanced, usable forms: in this case allowing for elasticity, longevity, and a silk-like texture. Inspired by the CMYK printing process, each watch takes the appearance of a specific dilution of black, 31%, 61% and 100%. The resulting unpigmented shades are applied to both the PVD coating of the steel watch cases and the rubber straps.
