On at a very low reserve. The Movement and case signed by one of the top Swiss watch makers, Adolphe Nicole; an early example of his work, key wound, before his moving to the UK and inventing the keyless winding watch (see quotes below) and the set-back for chronographs..Quotes.From Fondation de la Haute Horlogerie: 'Adolphe Nicole, a Swiss watchmaker working in London, filed a patent for a system that returned the chronograph hand to zero in 1844. He filed the patent again, this time in Paris, in 1862. From the mid-nineteenth century, Swiss production was clearly overtaking English production; Swiss watches now accounted for over half world production'. From Leigh Extense: 'By the early 19th century a number of innovators were exploring ways to allow a watch to be wound without a key, therefore taking away the need to open a case and to have to keep a key in close proximity to the watch, whilst others were adding to this to find a way to set the hands without a key as well. Thomas Prest, a former apprentice and then workman to John Arnold, was one of the first to apply for a patent, granted in 1820, for a movement with key-less winding, although his still required the case to be opened to set the hands, and this was taken up by a number of well-known makers including Arnold & Dent. But it was the invention of Adolphe Nicole of Dean Street in the County of Middlesex, watch maker, UK Patent 10,348 granted on the 14th of October 1844, that had the advantage of allowing both winding and hand setting from one stem operated from the top of the watch, with either fusee or going-barrel movements, and alleviated the need for the case to be opened at any time and therefore keeping the movement dust free. In 1846 Edward John Dent acquired the rights to this patent as sole licensee and started using it on watch movements, although it is probable that Nicole continued to make the movements on behalf of Dent. That Dent allowed others to use this system is shown by those movements signed by, among others, C.F. Hancock, E. White and Nicole Neilson & Co, all having Patent engraved on the backplate. Early forms of this system had the intermediate wheel in constant contact with the centre wheel, as seen in both examples in this exhibition, but Dent soon realized that this meant unnecessary friction on the motion work and an alteration was made to the engaging gear whereas the intermediate wheel was in constant contact with the going-barrel and only moved onto the center wheel when winding occurred. Dent’s continued to use this Nicole system until 1862 (note from the auctioneer: Dent later proceeded to supply cases to top watch makers under the name Denison) From Phillips: 'The turning point in modern horology design was unveiled in 1844: a London-based Swiss watchmaker, Adolphe Nicole developed a system that allowed the hand to return to zero, which granted him a patent: the 'cam-actuated lever', featuring the distinguished heart shape. Still today, it holds the stage in many chronograph mechanisms. Nearly twenty years later, Féréol Piguet conceived and realised a mechanism that incorporated a reset function. This discovery granted the Nicole & Capt manufacturer a patent, thus launching the first pocket watch displaying the three basic functions that we shall be meeting later in all the following chronographs: start, stop and reset to zero after indicating the elapsed time. At this point, the history of the chronograph stops, takes time, and waits for the next revolution to shake the very foundations of horology world.
