	Within the second-generation cluster the 6611 is the fluted-bezel reference, sitting alongside the smooth-bezel 6612 and the diamond-bezel 6613. It kept the 36mm Oyster case and the 18k gold-only catalogue of the originals, and ran for three years before the 1803 and its siblings replaced the whole group around 1959. The shared origin story (Marc Huguenin's patents, the Presidential nickname, the full cluster roster) belongs to the [[Reference:6510\|6510]] entry~~. What follows is specific to the 6611: the bracelet and dial it introduced, the upgraded caliber, its metals and sub-variants, and the steel examples that complicate its history~~.

	The 6611 succeeds the 6510 and 6511 roughly a year after their 1956 Basel launch. The dating is not ~~quite~~ unanimous: Sotheby's groups the 6611 with the 1956 originals, while Monochrome and Rolex Magazine place it at 1957. The 1957 reading is the common one and matches the President bracelet's own introduction date.		The 6611 succeeds the 6510 and 6511 roughly a year after their 1956 Basel launch.

	The reference anchors the second-generation 66xx cluster. The 6611 takes the fluted bezel, the 6612 the smooth bezel, and the 6613 a factory diamond-set bezel; the late 6611B carries a slightly thicker movement plate. ~~This three-bezel lineup is something the~~ 6510/6511 ~~pair never had — the originals were~~ a two-watch, bezel-finish ~~pair, while~~ the 66xx cluster is a proper range. By about 1959 the 1803 and its siblings take over and the Day-Date moves into its long 4-digit era.		The reference anchors the second-generation 66xx cluster.

Everything that separated it from them landed in a single step in 1957, which is why the 6611 reads as the start of the modern Day-Date rather than a minor update.

	Case numbers from the auction record sit a little above the originals' range (214,124 on a 1956/57 yellow-gold example, 401,546 on a 1958 white-gold 6611B), consistent with the 1957–1959 window. No Rolex archival production figure has surfaced. The cluster as a whole gives way to the 1803 around 1959, and from that point the President bracelet and the SCOC dial that the 6611 introduced become Day-Date standards.

	The 6611 carries the second-generation caliber 1055, the version watch registries label 1055B. It keeps the running gear of the first-generation movement (automatic, 25 jewels, 18,000 vph, 28.50mm across) but stands about 0.1mm taller at roughly 7.1mm and adds the two upgrades that matter. The balance becomes free-sprung with Rolex's Microstella regulating screws, paired with a Breguet overcoil, and the movement is COSC chronometer-certified. The midnight changeover becomes instant, fixing the gradual day-and-date transition that hobbled the first-generation 1055 and is usually blamed for the 6510/6511's single-year run. The full caliber lineage sits on [[Reference:Movements]].		The 6611 carries the second-generation caliber 1055, the version watch registries label 1055B.

	Auction catalogues mislabel these early movements. Antiquorum's 2002 steel lot lists the caliber as a 1556, a movement that did not exist until the 1803 era; the watch in fact carries the second-generation 1055. The ~~label to trust is the~~ dial and the construction~~, the Microstella balance and the chronometer certification, not the~~ caliber number ~~a cataloguer reached for~~ decades ~~later~~.

	The 6611 is the first Day-Date to wear the President, the three-piece semi-circular-link bracelet designed for this watch and now inseparable from it. The 6510 and 6511 launched on the Jubilee; the President arrives here in 1957. One of the earliest examples in the record is the President on the German-script Phillips lot, its folding clasp stamped 2.57. The bracelet is widely attributed to Gay Frères on contract to Rolex, though ~~that maker attribution rests on dealer and blog sources rather than~~ primary documentation. The bracelet's name is older than the watch's: a 1957 Italian newspaper advertisement reproduced by Rolex Magazine already calls it the "President," years before Lyndon Johnson's presidency attached the name to the watch itself in the mid-1960s. The cross-family detail sits on [[Reference:Bracelets]].

	~~That advertisement is useful because it names the bracelet, not just the watch.~~ The Italian copy describes the Day-Date as solid 18k gold with bracelet "PRESIDENT" 7286/16; the same Rolex Magazine piece ~~also~~ reproduces a 1958 Canary Islands catalogue and a 1959 German advertisement using the President/Präsident bracelet language. ~~For the 6611, that makes the bracelet~~ name a launch-period sales term ~~rather than a later American political nickname applied backwards~~.

The name was a launch-period sales term before it was anything else.

	As with the originals, the bracelet on a surviving 6611 does not always match the head: clasp date codes date the bracelet, not the watch, and service swaps are common across seventy years.

	The sources do not agree on how many exist or what to call them. Antiquorum counts six, Monochrome five, and Phillips four; the prize-watch and prototype framings are treated as one population by some and two by others. The most expensive of them, an ex-John Goldberger steel example with case number 99,272, was sold by Monaco Legend in 2024 as a reference 6511, not a 6611, on the strength of its first-generation caliber 1055 and riveted Oyster bracelet. The steel Day-Date is best treated as a disputed branch shared between the two reference numbers rather than a settled 6611 variant.		The sources do not agree on how many exist or what to call them.

	Antiquorum's 2002 lot essay gives one more version of the steel story: it says the six steel watches followed a marketing test in which demand proved stronger for gold, after which Rolex stopped steel production and kept the Day-Date in precious metals. That ~~explanation should be treated as an~~ auction-house ~~account, not~~ Rolex archive, but it explains why steel 6611s sit awkwardly between prototype, school-prize watch, and aborted-commercial-reference categories.
