Provenance: According to Jagger Barraud No. 750 was aboard H.M. Ship Ariadne under the command of Lieut. Gordon. Whilst at Port Louis a Mr. Newman aboard the vessel comments "I esteem Barrauds Chronometer 750 so much that I use it as a regulator to five others on board by comparing them every day". The Marquis of Huntly also commented very favourably on the chronometer's performance during a voyage which commenced on the 10th May, 1822. Jagger's supplement also notes Barraud 750 as 'said to have been used by the U.S. Navy in W.W.1 and then laid up at Naval Observatory until W.W.2, then disposed of. Also listed in C.L.R.B. under dates Sept., 1850 - January, 1851.' Paul Phillip Barraud (born 1752) worked with his father at first until his death in 1795 after which Barraud turned his attention more towards chronometers. Using the valuable experience gained whilst working on Mudge's timekeepers with W. Howells and G. Jamieson to good effect, he became very successful. After his death in 1820 the business was continued by his sons taking John Richard Lund, a former apprentice of John Pennington (who developed the auxiliary compensation balance weight to correct for middle temperature changes), into partnership in 1838. Two comparable eight-day movements by Barraud (numbers 986 and 2/570) are illustrated in Bertele, Hans von MARINE & POCKET CHRONOMETERS, History and Development pages 162-63 (Figures 159a and 161a). The brass bowl and case of the present timepiece are probably mid 19th century purpose-made replacements as it would appear that Barraud's chronometers made during the Regency period tended to be housed in a different design of bowl with convex glass to the screw-down bezel.
