This limited series of 100 pieces pays tribute to Louis-Frédéric Perrelet, inventor of the split-seconds mechanism in 1827. Each of these split-seconds chronographs bears number i because they are made unique by the different combinations of guilloché patterns and coloured lacquers on the dials. Handengraved automatic movement, 28,800 V/h, 30 rubies, Glucydur balance. Hours, minutes, small seconds and date display. Steel case on a Mississippi alligator strap.
