The production of the references 6263 and the 6265 started around 1970. These were the last iterations of the manual winding Daytona before eventually they were replaced by the automatic ‘Zenith’ chronograph with the caliber 4030 in 1988. 
This piece sums up all the appealing characteristics this model can offer: the black dial is adorned with the famous big red Daytona above the subsidiary dial for hour register. Furthermore, this watch is in very original condition as it still has its original screw-down pushers, bezel and the correct 78350 bracelet with 571 end links.
In addition to retaining its original elements, the condition of the watch can only impress the collector as they have been well preserved and the case still retains good proportions. 
Finally, this watch is offered on behalf of its original and only owner and is accompanied by its original Guarantee, invoice and presentation case making this lot particularly attractive.
