Richard & Tucker Nunn Ltd. were retailers of clocks and watches at 108 Hatton Garden, London. The company acted as a dealer for Smiths English Clocks Ltd., which was one of the most prolific clockmakers of the 20thcentury. In 1959 the firm merged with another dealer for Smiths Clocks called Grimshaw Baxter & J.J. Elliott Ltd. to form Tucker Nunn & Grimshaws Ltd. The new company continued until at least 1978.
