William Gillett founded the firm. He first began as a clock maker in Hadlow, Kent under the patrionage of Lord Sackville-West. He then moved to Clerkenwell, London and from there to Croydon where he established his business in 1844.
Charles Bland became a partner around 1854 and brought his considerable skills as a salesman to the company and it was through his influence that turret and public clocks were first introduced to the business. The company was one of the first steam-powered clock factories in the world and in 1868 the well known clock tower at the factory was built as a working advertisement.
The company became known as Gillett & Bland
