Accompanied by a Breguet certificate dated 26 August 2019 confirming the sale of No. 4129 to Chez Wenham, St. Petersburg on 13 October, 1826 for 2,000 Francs. The inking chronograph is believed to have been invented by the Parisian watchmaker Nicholas Matthieu Rieussec (1781-1852) in 1821. Rieussec who was watchmaker to Louis XVIII, developed his chronograph to time horse races, the system allowed a drop of ink to be deposited onto the dial to record different finishing times (see: P. Friess, Patek Philippe Museum, Index Vols III & IV, p.51). Fredrick Louis Fatton, one of Breguet's best workmen, invented and patented his own inking chronograph system two years after Rieussec and this was further perfected by Breguet.
