Similar watches: Antiquorum, Geneva, October 20, 1991, lot 305, sold for the amount of CHF 39 100. Early self-winding watches: Since the publication of the works of Alfred Chapuis and Eugène Jaquet, this model of self-winding watch is attributed to Moÿse Gevril (Le Locle, 1749-?), watchmaker living at Crêt-Vaillant du Locle (1952, pp. 179-180; 1956, pp. 188-190). The watch mentioned in these two books bears his name engraved with an etching needle but is also fitted with a barrel spring bearing the signature and date “DL 9 c January 14, 1781”, probably for Daniel Henry Lequeureux, maker of springs barrel, living Cret du Locle, also working for Philippe DuBois (1738-1808), between 1782 and 1797. In the recent literature, Jean-Claude Sabrier illustrates three similar watches, unsigned, which he attributes to this workshop (2011, pp. 160-173), while Richard Watkins brings some additional information (2013, p. 53, pp. 144-145; 2016, pp. 55-56, pp. 164-165). Our watch is the fourth known example of this type. In the absence of further details, we also attribute this watch to this watchmaker active in Le Locle, especially as its case is stamped with Neuchâtel “chevrons” hallmark, knowing now that the ebauche is probably from the workshops of Philippe DuBois.
