Dial: enamel. Movm.: 1/2 plate movement, 2 hammers / 2 gongs, gold screw compensation balance. According to our information this is the most complicated pocket watch with cover winding Haas ever created. Haas & Cie. In 1848 the brothers Leopold (1827-1915) and Benjamin (1828-1925) Haas, both knights of the Légion d'honneur, founded the ANCIENNE MANUFACTURE DES MONTRES HAAS & CIE in Geneva. The company excelled in unique and exceptional pieces and achieved its reputation with exquisite watches that pass for modern even today. Rare treasures such as the split second chronograph and beautifully wrought pocket and wristwatches were created in accordance with the manufacturer's fundamental motto of simplicity, technique and elegance. Benjamin Haas invented a form of winding where the mainspring was wound by opening the front cover of a hunting case watch. Patents, 1873, p. 48 illustrated and outlined British patent No. 3945, issued Dec. 2, 1873 to B. Haas. This patent was licensed to other makers. 1884 Haas changed their name to Haas Neveux & Cie, to communicate that new family members had taken positions in the company. At the same time the original logo of B.H. & Co. (for Benjamin Haas & Co) was changed to a small running hare and the letters HNC in an oval shape - representing the dynamic attitude of the company. In 1896 Haas Neveux & Cie establishes a record with an ultraflat 2mm movement for a ladies' watch and wins a first price for precision in the 1902 competition of the famous "Observatoire de Genève". English patent No. 3945 of December 2, 1873 was granted to Benjamin Haas for the development of a novel and unusual winding mechanism, which used the energy that is generated when the front cover of the watch is closed. Haas improved the original idea further and his watch possesses a well-developed system with a 36-hour power reserve (generated by twelve closings). Haas changed the going train by adding an additional wheel so that a single closing was able to achieve three hours' winding. He also invented a safety device which disengaged the mechanism when fully wound and thus prevented any damage to the cover. #45949"

Haas Jeune”, then “Haas Neveux & Co.”, is one of the oldest Swiss watch manufacturers. The Haas signature has always been one of the most sought after, thanks to the impeccable standards of the company. Haas gained a reputation as a manufacturer of fine chronometers, chronographs, and highly complicated watches. Among their most notable creations was the “remontoir perpétuel à décrochement” (1867 and 1873), a perpetual calendar (1872) and later the first ultra-thin watch movement (circa 1896). Benjamin Haas patented winding-mechanism by closing the cover, “remontoir perpétuel à décrochement” In 1867, Benjamin Haas patented an interesting winding mechanism by closing the cover, which transmits the power via two levers to a ratchet wheel on the barrel arbour with a safety device disengaging the mechanism when fully wound. The design was quite successful, and Haas employed it in some of his best watches, mostly with horological complications. The initial idea was progressively improved, and the one employed in the 1890’s is a welldeveloped system with a 36-hour power reserve generated by only twelve closings. To accomplish this, Haas changed the going train, adding an additional wheel, which allowed him three hours winding by a single closing. He also designed a safety device disengaging the mechanism when fully wound, which was necessary to prevent damage to the cover.
