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 Geneve"." 2015 - Sotheby's 13 May 2015 25,000 - 35,000 CHF SOLD. 31,250 CHF "Haas Neveux & Cie A FINE AND RARE EXTRA THIN PLATINUM 'ART DECO' OPEN-FACED MINUTE REPEATING PERPETUAL CALENDAR WATCH NO 20506 CIRCA 1920 • cal. 17''' manual winding jewelled nickel-finished lever movement, stamped with the seal of Geneva, two polished hammers repeating on two gongs, cut bi-metallic compensation balance • silvered dial, painted Breguet numerals, four subsidiary dials for the month combined with leap year, day, date, and constant seconds combined with moon-phases, outer minute track, blued steel hands • platinum case, snap-on case back with yellow gold monogram COF, slide on the band for repeater at 3 • case and dial signed"
