* Jose R de Losada is listed on page 492 in Brian Loomes’ Clockmakers of the World: 21^st Century Edition.  This pre-eminent chronometer maker worked “By appointment to several Royal courts” and specialised in selling to Spanish speaking markets. He is quoted by Rupert T. Gould R.N. in his famous book The Marine Chronometer: Its History and Development on page 104 “In 1864, as the result of a competitive trial, there were purchased 38 chronometers made by J.R. de Losada (a Spanish maker resident in London, where he acquired a considerable reputation).”

Jose Rodriguez de Losada  was born in Spain and at one stage was attached to the court of Madrid. He then emigrated to England where he worked initially for James Moore French. He made movements for Kullberg and James Poole and continued to make chronometers and clocks for the Spanish government and the Royal Observatory at Cadiz and had a number of high honours conferred on him by Queen Isabella II.
