Joseph Sewills & Sons was a Liverpool based watch and clock company that produced precision marine instruments and chronometers, clocks and watches from 1800 until the firm's final demise in 2001. Sewills manufactured ship's clocks for the British maritime industry, and was known as the "Maker to the Admiralty." In later years, Sewills produced British-designed Swiss-Made watches, similar to Arnold & Sons and Graham. The Sewills "Carmania" is an officially certified (COSC) chronometer automatic of a design very similar to the Ulysse Nardin "1846" marine chronometer. The Carmania was a British luxury liner that was converted to military use during WWI, and won an important battle with a German destroyer off Trinidad in 1914. The Carmania model was among the last of Sewills chronometers ever produced, and the COSC chronometer certificate on this piece indicates that chronometer testing was completed on 5/28/98. This watch is all original and complete, in near-NOS condition, and comes with signed inner wooden box, outer box, chronometer certificate, and signed original purchase receipt, dated 3/13/00.
