Alexandre Hüning SA, a watchmaking firm based in Geneva was known as a manufacturer of both plain and complicated watches. In 1905 and 1908, Hüning won the Geneva Observatory contest for the best watch. The present watch is made according to the patents obtained by Strömgren and Olsen - for a note on which, see lot 74. The deck box has a retailer's plaque for Cornelius Knudsen, a scientific instrument making company based in Copenhagen, a firm for which Jens Olsen worked as the workshop manager (see: Klassik Uhren, March 2017, p.6). Interestingly some similar examples of this watch are known with the Knudsen retailer's name upon the dial alongside those of Strömgren and Olsen.
