Notes

Several pocket chronometer movements with sugar-tongue compensation were left in gray by Thomas Earnshaw and subsequently finished and sold by his son in the 1820's - 1830's.An almost identical pocket chronometer movement, No. 1035/3932 in a silver hunting-case made in 1837, from the collection of the Time Museum (Rockford, Illinois) is described by Anthony Randall in the Museum catalogue, page 157.Hunt & RoskellWere among the largest retailers in London. They employed the best makers, such as James Fergusson Cole and others. In this case they decided to use a movement of the inventor of the most popular modern chronometer escapement Thomas Earnshaw.
