The collection is called the C Scale, inspired by watch and music historian Rorrie Owens. When Richardson began to make the gears and bridges in the mechanical movement in gold, platinum, and silver, he noticed that the sound changed when winding the watch and when it was ticking. Looking back at his studies of the molecular structure of precious metals, he began to understand that each precious metal gives off a unique sound. The Nkiru BL2015-NK mechanical movement is an arrangement of these sounds. The 2.5hz frequency Nkiru timepiece creates a space of vibration and harmony around the wearer. It is not just a timepiece. It is music.
