Gross weight of assembled watch 77.1 dwt (119.8 g). Watch is accompanied by an extract from the Lange archives detailing its November 11th, 1886 sale for 457 Deutsche Mark to Otto Fleischhauer along with four other watches of the same calendar series. Watch is also accompanied by a German language magazine with photos and info of a similar example that is nine serial numbers away from the present watch. An extremely rare watch of eye-catching and novel design, this calendar arrangement by Otto Fleischhauer was registered with the Berlin patent office on July 15th, 1883. Fleischhauer contracted the production of a small group of these watches to Moritz Grossmann who initiated their production but passed away suddenly in early 1885. This series of watches was then acquired, finished and sold by A. Lange & Söhne and in total it is believed that only 20 of these Fleischhauer triple-calendar watches were finished and sold under the Lange name. CONDITION: Mvt: GRO, good calendar function although timekeeping hands should be re-indexed as date advance is occurring as hands pass 5pm rather than at midnight...
