First what is a Keystone? A keystone is a central wedge in an arch that locks all other pieces of an arch in place. It is the part of an arch that all other parts depend upon. Pennsylvania's popular nickname, "The Keystone State," refers to this necessary element. The idea for RGM's Keystone hands came from a set of hands Roland Murphy was given when he was in watchmaking school in Lancaster, PA. They were a thin set of gold hands with a Keystone on each hand. He found out from some old watchmakers that they were made by Keystone Watch Company which was in Lancaster, Pa between 1886 and 1891. Never forgetting these beautiful hands they eventually became the inspiration behind the Keystone hands he designed for RGM.
