Abstract Working in Lincolnshire in the 1720s, John Harrison (1693–1776) established a unique approach to making accurate pendulum clocks that was born from his experiences in the family business that served country estates in Yorkshire and Lincolnshire. The chapter charts Harrison’s early clock-making practice, inspired by local traditional clocks, and his unique interpretation. He used wood for the frames and most of the wheelwork before key elements of his precision timekeeping crystallised in the making of an estate clock for Brocklesby Park in Lincolnshire. Notably, the elimination of requirement for lubrication formed a solid bedrock for his life’s work in precision in this field. It examines Harrison’s early influences and progression of thinking through documentary evidence and artefacts to introduce the beginnings of his unique approach to precision pendulum clock making.
