292-4283 Pocket watch: significant Geneva chronometer with 7 complications, B. Haas, Geneva, circa 1890 Ca. Ø54mm, ca. 150g, 18K gold, à-goutte savonnette, engine-turned, dome inscribed "CHRONOMETRE", signed B. Haas Jne & Cie No. 15333, top-quality Geneva Anker chronometer, perpetual calendar, moon phase, age of the moon and minute repeater, very well-preserved enamel dial, gold hands, in very good condition and in working order. Very few pocket watches of chronometer quality feature complications. This is because it was difficult to achieve the accuracy required of a chronometer in watches that had additional complications. Only a few manufacturers, such as Patek Philippe, Vacheron & Constantin and, indeed, B. Haas, were capable of doing so. These watches are now particularly sought-after and highly prized collector’s items! The ‘sister watch’, No. 15773, was offered for sale in Geneva in 2010 (https://www.cortrie.de/go/PoA). Another of these watches, No. 15849, even exceeded the upper estimate of CHF 55,000 (https://www.cortrie.de/go/7Z6). 20.000 € - 50.000 €

292-4332 Pocket watch: significant chronometer with certificate, Geneva Watchmaking School, signed Francois LeCoultre Ca. Ø51mm, ca. 105g, 18K gold, No. 8684, Vacheron & Constantin Geneva movement, Anker chronometer with Geneva stripes and the Geneva Seal, signed François LeCoultre, enamel dial bearing the signature of the Geneva Watchmaking School, distinctive gold hands; in working order and very well preserved, with original certification papers (Bulletin de Genève) from 1942. A school watch bearing the signature of François LeCoultre is an absolute rarity and a historically significant collector’s item from the history of Swiss watchmaking. Such pieces are generally pocket watch masterpieces produced as part of a student’s training; they were crafted by François LeCoultre at the Geneva Watchmaking School under his direct supervision as a masterpiece or final project (hence ‘school watch’) and signed by him in his capacity as a professor. François LeCoultre (born 14 December 1883; died 25 January 1965 in Geneva) was an outstanding Swiss watchmaker who achieved fame primarily as a long-serving professor at the Geneva Watchmaking School (École d’Horlogerie de Genève) and as the author of the global standard reference work on complicated movements. 7.000 € - 15.000 €
