A Monsieur Leblond Watch No. 2751, completed on 19 September 1931, sold on 3 January 1941, for the sum of 53' 000 Old Francs. Gold keyless watch with jump hours, perpetual calendar, centre-seconds and winding indicator. Notes Note: This watch incorporates an instantaneous calendar mechanism with a single setting pin, and most unusually for the period, a jumping hour hand. Such a feature was usually applied to the Première Classe repeating watches dating from the early 19th century, but very rarely found on a watch made in the 20th century.
