This watch is number six of a limited edition of ten. The series was made according to the design of George Thomas and the manufacturing was supervised by the late Mr. Adolf Benz of Comor Watch Co. The cage was made and the watch was finished by Georges DuBays, one of the last old-time masters in Chaux-de-Fonds. This watch number 6 is the only one in the series with the zodiac engraving on the spring barrel.
