Special classification between makers who had presented to the timing contest 5 chronometers or more during the year. This classification was based upon the Humber of bulletins awarded at the timing contest and on the average of marks obtained by the five best chronometers. Unlike the chronometers which could be awarded with a Bulletin de Première Classe together with a first, second, third prize or a mention, one prize only was awarded, each year, between the markers.
