Very little is known about the London based watchmaker William Reid. He had his shop in Ball Alley, Lombard Street. In March 1830, he declared bankruptcy.

The stamp “DW” in the case could indicate the case maker Daniel Willmott, who was active around 1810. However, a similar stamp was used by Daniel Walker. He is recorded as a case maker in 1798, 1799 and 1802.
