Notes

An excellent example of a Vacheron Constantin deck chronometer made for the British Hydrographic Service, excellently finished and in very good condition.The British Hydrographic Service was established in 1795. The worldwide pre-eminence of the Royal Navy in the 19th century meant that Admiralty charts became the global standard for all ships, whether warships or merchantmen. The Service was the surveying arm of the Royal Navy. It acquired top-level recognition early in the 19th century, when the Hydrographer of the Navy, Thomas Hurd, persuaded the Admiralty that their charts should go on general sale, and that surveys at sea would best be carried out by Royal Navy ships. For surveying purposes, the Service needed top timekeepers, such as the present lot.
