The chronometer was exhibited at The Melbourne Exhibition 1880, 'The Advocate', 23rd October, 1880 states:- '...then there is a two day marine chronometer of the usual English pattern, but the case is of colonial blackwood and of an improved form. The usual wooden top cover is dispensed with and a strong plate-glass panel substituted so that the works may be inspected at any time without opening the case'. Thomas Gaunt was a clockmaker and jeweller of outstanding ability. This must have been the opinion of most Government Departments of the day for they commissioned the newcomer from London to provide clocks for many of their buildings, including the law courts, post offices and railways. The most famous Gaunt clock is, perhaps, the giant figures of Gog and Magog situated in Royal Arcade.
