H.S.527-3635, Serial No. 14240 to front; with a second spare field case and a canvas sheet.The box 17cm (6.75ins) high, 28cm (11ins) wide, 21cm (8.25ins) deep. The chronometer making firm Thomas Mercer of St. Albans was established by Thomas Mercer (1822-60) at North Road, London in 1858 before moving to 45 Spencer Street, Clerkenwell in 1860. Mercer became an active member of the British Horological Institute (established in 1858) where he lectured on the need to modernise the industry and served as honorary treasurer from 1875-95. After occupying several addresses in Clerkenwell Mercer relocated the core of the business to St. Albans in 1874 setting up a factory behind his house at 14-15 Prospect Road. Although the bulk of the businesses work was undertaken in St. Albans Mercer personally made weekly trips to Clerkenwell to deliver/collect parts finished by specialist outworkers as well as visit the Horological Institute. In order to maintain a presence in London Thomas Mercer opened an outlet 18 Westmoreland Road, City Road in 1890. Succuss at the Greenwich trials was also always considered important to Mercer who entered instruments every year; he was placed second in 1881 and his son, Frank, came first in 1911. In 1900 Thomas Mercer accepted an invitation to judge at the Universal Exhibition in Paris but unfortunately caught a cold on the ferry crossing and died soon after his return. The business was subsequently continued by his successors becoming of the most prolific suppliers of chronometers and other timepiece for industrial, maritime and domestic purposes and continued trading in St Albans until 1984. The current chronometer was developed by Mercer for surveying purposes. Fitted with electrical contacts and rated to sidereal time the timepiece is designed to be used in conjunction with a ticker-tape chronograph (see previous lot) and an Admiralty pattern 45 degree prismatic Astrolabe or theodolite (to allow accurate measurement of angular distance, or 'zenith distance' between a given star and the zenith). The very accurate timing of the zenith distance of a given star can provide precise 'local time', and, through comparison with Greenwich meantime, allow accurate longitude and latitude of the observer to be established.
