The 6611 is the fluted-bezel member of the second Day-Date generation, alongside the smooth-bezel 6612 and gem-set-bezel 6613. Reference histories usually place it from 1957, after the 6510 and 6511 launch pair. Auction catalogues add an earlier example: [https://www.phillips.com/detail/rolex/CH080115/50 Phillips dates one gold 6611 to 1956]. Rolex dates the Day-Date’s debut to 1956; reference-level start dates remain unsettled.

The 6611 is associated with the 1055/1055B movement generation, the “Superlative Chronometer Officially Certified” dial wording, and early President-bracelet fitment. [https://www.phillips.com/detail/rolex/CH080115/41 Phillips lot 41 for the earlier 6511 records a President bracelet], placing published evidence before the 6611. Steel school watches and prototypes form a separate, disputed record~~; the article describes them apart~~ from ordinary gold production.
