The watch chronometer and instrument retailer's business was established by Samuel Smith as a jewellery shop at 12 Newington Causeway in south east London in 1851. In 1875, Samuel Smith died at the age of 49; during his time in control of the firm, it had experienced a rapid rate of growth. During 1872, it relocated the centre of its operations to 85 The Strand, next door to the premises of Charles Frodsham. In 1885, a large business operating as diamond merchants emerged, based at 6 Grand Hotel Buildings, Trafalgar Square, and from 1895 at 68 Piccadilly.
