Mudge trials his chronometer Thomas Mudge sent his first chronometer for trials at the Royal Observatory in Greenwich in 1774 and again in 1767–1777. The timekeeper’s performance was so good during its second trial that it was not equalled for nearly a century. See the Mudge Green Timekeeper on Clocktime – one of a pair of timekeepers that he developed in his pursuit of the Longitude Prize. Image Credit Marine Chronometer; spring-driven clock; clock-case.
