Flyback chronograph variant of the Valjoux 23, produced from 1954 to 1974. Features a 9-column wheel and the flyback function that allows instant reset and restart of the chronograph without stopping. Like the Cal. 23, it lacks the 12-hour counter (only 30-minute counter at 3 o'clock). The flyback complication was particularly valued for aviation and timing sequential events. Part of the celebrated 23/72 column-wheel family.
