Reference:6611: Difference between revisions

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. [Phillips lot 41 for the earlier 6511 records a President bracelet], placing published bracelet evidence before the 6611. Steel school watches and prototypes form a separate, disputed record; the article describes them apart from ordinary gold production.

| Histories commonly give 1957–59. Phillips dates case 214,124 to 1956. Steel school-watch catalogues give conflicting dates; they leave the commercial production span uncertain.

| Auction records document President bracelets on individual examples; original delivery must be assessed watch by watch

| Auction and collector literature uses “6611B” for later examples, including the white-gold Phillips watch. The suffix’s meaning remains undocumented in the Rolex factory material reviewed.

[https://www.rolex.com/about-rolex/history/1953-1967 Rolex dates the Day-Date debut to 1956]. [https://www.sothebys.com/en/articles/the-rolex-day-date-a-complete-collectors-guide Sotheby’s account] describes the 6510 and 6511 as the first pair and says they were replaced after one year by the 6611. [https://monochrome-watches.com/history-rolex-day-date-1956-present-president-watch-in-depth-review/ Other histories commonly place the 6611 at 1957]. Phillips, however, dates case 214,124 to 1956. That catalogue date anchors one watch to 1956; the reference’s production boundaries remain uncertain.

The 6611 carries a fluted bezel. The 6612 is the smooth-bezel sibling, and the 6613 has a gem-set bezel. The 1803 appears around 1959–60 in the histories cited here. The cited record leaves the exact 6611 changeover and a three-year run unconfirmed.

Two Antiquorum steel school-watch entries carry very different dates. The 2002 lot is catalogued as circa 1959 and has a caseback engraved for the Geneva watchmaking school in 1963. The 2013 lot is described as made in 1954, has no case number, and is called a practice watch in the auction note. Those steel-watch descriptions are separate from the commercial gold 6611 chronology.

The 1055 generation is described in [https://monochrome-watches.com/history-rolex-day-date-1956-present-president-watch-in-depth-review/ specialist watch histories] as an automatic chronometer movement with a free-sprung Microstella balance; some accounts also specify a Breguet overcoil and an instantaneous day-and-date change. Those features describe the movement family in specialist literature. They describe the movement family; the cited sources leave the 6611’s production span and its relationship to the 6510/6511 open.

The steel school-watch catalogues should be read as records of what each house published. Antiquorum listed caliber 1556 in 2002 and 1066 in 2013. Phillips’s 1055/1055B gold-watch records do not resolve those steel-watch identifications. The two catalogue caliber labels remain unresolved; a movement inspection or factory record would be needed to identify either steel watch more firmly.

Phillips and Antiquorum describe 36mm cases with fluted bezels, screw-down crowns and backs. Phillips specifies a plastic crystal on lot 50. Rolex’s history page records gold and platinum within the Day-Date line. The 6611 lots reviewed here document yellow, pink and white gold; a platinum example remains unverified.

Catalogue wording for the 6611B case shape varies. Antiquorum calls case 384,689 “Boitier rond,” while it describes cases 386,339 and 397,072 as tonneau-shaped. These are the houses’ descriptions of individual lots; the records reviewed leave separate case variants unconfirmed.

Auction records describe steel Day-Dates, though their grouping and reference attributions remain disputed. Antiquorum’s 2002 lot calls a steel watch a 6611, says six were made, dates it circa 1959, and describes it as a prize for Geneva watchmaking-school students. The lot also says the model was first created as reference 6511 and lists caliber 1556. These are Antiquorum’s statements; the same catalogue contains internal dating and reference tensions.

Antiquorum’s 2013 school-watch lot is also titled 6611, but it gives 1954, has no case number, lists caliber 1066, and says unnumbered steel Day-Dates were donated as practice tools. Phillips later described four steel Day-Date prototypes with 1555-series movements and attributed their origin to Rolex watchmakers. These records concern different descriptions and may not count the same watches. Monochrome reports five steel 6611s; the exact count remains uncertain.

Auction catalogues use “6611B” for several later examples. Phillips applies it to the 1958 white-gold watch with caliber 1055B; Antiquorum uses it for gold and pink-gold watches. In the documented examples, it is useful shorthand for a sub-variant. Rolex’s factory material reviewed here leaves the suffix’s status as a separate case reference unresolved.

The 6611B records include yellow-, white- and pink-gold cases. The pictured white-gold example has no diamonds; pink-gold lots include both black diamond-marker and silvered dials. The Spanish-market Serpico y Laino watch has a Spanish day disc and a “Big Logo” bracelet that Antiquorum dates to 1958. That listing documents one regional configuration; it cannot be generalized to every 6611B.
