Footnotes
Thomas Prest, a Lancashire watchmaker, was apprenticed to John Roger Arnold in 1783 and later made foreman. In 1820, Prest was awarded a patent for his keyless winding system. Only around 210 watches were produced in Arnolds workshops using this mechanism between 1810. Hans Staeger states that No. 11 was until this point the earliest watch of this type recorded.
A similar eample can be found in Hans Staeger's '100 years of precision timekeepers' , Pages 557-556.
