Description
A chronometer is a navigational tool consisting of an extremely accurate timepiece that can be used to keep Greenwich Mean Time. Longitude can then be calculated by computing the difference between the chronometer's mean time and the ship's local time, measured against the position of celestial bodies.
This chronometer, used on Henry Walters' steamyacht, the Narada, was made by George P. Kullberg in London, who was famed for the precision of his manufacturers. Based on the serial number of the movement, it was made some time in 1898 or 1899 (after Henry acquired the yacht from Anthony Joseph Drexel Jr.), and finished with a dial, box and other fittings by John Bliss and Co. of New York City. The object then fit within an outer box (WAM 58.266B), that was secured to the bridge of the yacht.
