Derek Francis Pratt FBHI (9 May 1938 – 16 September 2009) was an English horologist and watchmaker. Regarded by many within the field as a highly accomplished 20th-century watchmaker,^[1] Pratt was particularly noted for his contributions to high-end timepieces produced under the Urban Jürgensen brand. Additionally, he gained recognition for his independent creations, including an oval watch in the style of Breguet and a reconstruction of John Harrison's H4 marine chronometer. His development of watches incorporating remontoires that act directly on the escapement, even within a tourbillon mechanism, is considered a significant technical achievement. Pratt's engine-turned (guilloché) dials are also recognized for their quality.
