The production of the references 6263 and the 6265 started in 1969, making this particular Daytona from circa 1971 an early production piece. These references stayed in production until 1987 and were the last Daytona references powered by a manual-wound chronograph movement. This movement was replaced by the automatic ‘Zenith’ chronograph caliber. The present lot is further distinguishable by the Sigma sign on the dial that signifies the use of gold, in this case that the hands and indexes were originally made from white gold. The sigma symbol was being used during the 1970's in collaboration with l'Association pour la Promotion Industrielle de l'Or (APRIOR). With the ever rising competition from overseas, the Swiss industry tried to promote the value of watches that used gold as material and differentiate those pieces.
