There is tantalizingly little information regarding James Andrews, the actual maker of the clock. He is listed working at 129 Hudson Street in 1820, but does not appear in New York City directories thereafter. In contrast, Thomas Richards is listed in New York City directories at 240 Pearl Street on the corner of John Street between 1802 and 1833, and his "maker's mark" is found on contemporary silver and flatware. Initially in partnership with John Sayre (1771-1852), they advertised in 1803 that the firm sold "Watches, plate and Jewellry". Sayre, a silversmith was working in other premises in Pearl Street from 1796, moving to 240 Pearl in 1802. The partnership dissolved when Sayre removed to 65 Maiden Lane in 1813. Richards sold silver by other makers after this. Examples with the marks of John Foster (active 1809-1835) and William Smith Pelletean (1786-1842) are recorded.

Richards also sold watches and clocks. In 1822 Simon Willard advertised that he was his agent for lighthouse clocks. Richards' partnership with William Morrell is listed in the New York City Directories from 1827-1833. Unlike Richards, no silver marked by Morrell is recorded, but as a clockmaker, in partnership with Henry Mitchell, he maintained premises across the street from Richards at 247 Pearl Street from 1816-1822. Morrell occupied 240 Pearl Street alone from 1836-1838, presumably after the death or retirement of Thomas Richards.

Around this time, the clock was sold. G. B. Prindle, whose name also appears stamped on the clock, is also listed as a jeweler and silversmith. As recorded on the dial plates, the clock saw service until recently for a succession of jewelers.
