Lot Essay

Thomas Porthouse is recorded at 16 Northampton Square 1840-1864. French joined him circa 1864. William Weichert is recorded working in London, 1865-1887 and Bute Docks, Cardiff, 1871-1885.
Weichert exhibited his chronometers in Paris in 1867, Havre in 1868 and won a Grand Medal of Merit at the Vienna Exhibition of 1873. He was maker to the Admiralty and to the Emperor of Austria who awarded him the Golden Cross and Crown and also the patentee of the centre seconds chronometer.
Tony Mercer (Chronometer Makers of the World, London, 1988, p. 252) describes him as 'a fine workman who made many chronometers and trained many of the craftsmen who kept the Bristol Channel shipshape'.
