List Of Chronometers On HMS Beagle
Chronometers were formerly used for the accurate determination of longitude by ships at sea. By measuring the time of local solar noon compared to the time of noon at a reference point the difference in longitude can be directly found. For this system to work, a timepiece showing the time at the reference point must be carried to the measuring point. A timepiece intended to remain accurate while subjected to the motions of a ship at sea and through extreme changes in environment, especially temperature, is called a chronometer. These were first built in the 18th century and were used extensively by mariners in the 19th century and into the 20th century, even after the widespread use of radio for time signals – the time signal was used to set the chronometer, but the instrument was still necessary to display the time. HMS ''Beagle'' was an Admiralty survey ship sent on three major expeditions. The first (1826–1830) was to survey the coast of South America in company with ...

Edward John Dent
Edward John Dent (1790–1853) was a famous English watchmaker noted for his highly accurate clocks and marine chronometers. He founded the Dent company. Early years Edward John Dent, son of John and Elizabeth Dent, was born in London on 19 August 1790. He was baptised on 18 October 1790, at St. Clement Danes Church in the Strand. Edward had a younger brother, William (born 11 February 1792). The boys' mother, Elizabeth, died while they were still young – she was buried on 16 May 1793. Interest in watchmaking At the age of 14, Dent became apprenticed to his grandfather, John Wright Dent, a tallow chandler. Under the terms of the indenture – dated 20 August 1804 – John Wright Dent was expected to find suitable lodgings for his apprentice. Fortunately, Edward John Dent's cousin, Richard Rippon, was willing to have him. Rippon was an expert watchmaker and Dent became fascinated by watchmaking and less interested in the business of making and selling candles. Indeed, Dent ...

New Bond Street
Bond Street in the West End of London links Piccadilly in the south to Oxford Street in the north. Since the 18th century the street has housed many prestigious and upmarket fashion retailers. The southern section is Old Bond Street and the longer northern section New Bond Street—a distinction not generally made in everyday usage. The street was built on fields surrounding Clarendon House on Piccadilly, which were developed by Sir Thomas Bond, 1st Baronet, Sir Thomas Bond. It was built up in the 1720s, and by the end of the 18th century was a popular place for the upper-class residents of Mayfair to socialise. Prestigious or expensive shops were established along the street, but it declined as a centre of social activity in the 19th century, although it held its reputation as a fashionable place for retail, and is home to the auction houses Sotheby's and Bonhams (formerly Phillips (auctioneers), Phillips) and the department store Fenwick (department store), Fenwick and jewel ...
