This chronometer was issued by the Royal Observatory, Greenwich, 22 November 872 to H.M.S. Challenger for her voyage of scientific discovery: it was returned from her 9 June 1876.
CHRONOGRAPHS
In the early years of the 20th Century there was great competition between the leading chronometer makers to design a chronograph which, when used in conjunction with a marine chronometer fitted with special electrical contacts, could make on paper a permanent recording of G.M.T., an increasing necessity for both Hydrographic and Ordnance Surveyors. Thomas Mercer, Victor Kullberg and William Lindqvist were all striving towards this goal. In his letter of 21 January 1908 the Hydrographer of the Navy requested the Astronomer Royal; Will you be good enough to deliver to Mr Lindqvist, Chronometer, Pennington 241, in order that he may fit it with his new Chronograph attachment. Lindqvist did this and thereafter used it with his Chronograph No. 2. It appears from correspondence in January 1908 between Lindqvist, the Astronomer Royal, and the Hydrographer of the Navy, that it was agreed to purchase for £57 Lindqvist's Chronograph No. 2 with Pennington's No. 241, it having now been fitted by Lindqvist with the necessary electrical contacts of his design.
