Throughout Rolex’s history, the "crowned" firm has continued to constantly innovate classic styles established early on in their history. The Datejust is one of the their most successful models, first introduced in 1945, and still in production today. At the time of manufacturer of the present reference 6305/1, the Datejust had just turned 10. During those 10 years, Rolex continued to evolve the Datejust, refining its personality to become one of their most beloved watches today. In between the lugs at 6 o’clock, just above the reference number, is an inscription that reads “Brevet”, which means patented in French. Made shortly after Rolex’s introduction of their patented twinlock crown, it used two rubber gaskets that allowed a water resistance rating of 100m/300ft. The matte black dial with gilt printing is exceedingly rare within this reference and has irresistible appeal. Overall in wonderful, unrestored condition, one struggles to believe that the present lot is already over 60 years of age as it does not only have a very contemporary look but looks as if it left the Rolex factory just recently.
