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 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, its case number is unrecorded, and the auction note calls it a practice watch. 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.

Antiquorum’s steel school-watch catalogues list calibers 1556 (2002) and 1066 (2013). Phillips’s 1055/1055B records describe the gold watches; the two steel-watch caliber labels remain unresolved. The two catalogue caliber labels remain unresolved; a movement inspection or factory record would be needed to identify either steel watch more firmly. | |||

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. | Auction records describe steel Day-Dates, though their grouping and reference attributions remain disputed.

The auction descriptions differ in reference numbers, movement labels and dates; Monochrome reports five steel examples, and the available record leaves their overlap uncertain. | ||
The ex-John Goldberger steel watch with case 99,272 was sold by Monaco Legend in 2024 as a 6511. Its 1055 movement and riveted Oyster bracelet support keeping it apart from the later gold 6611 specification, though its prototype reference remains contested in published histories. | The ex-John Goldberger steel watch with case 99,272 was sold by Monaco Legend in 2024 as a 6511.

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. | Auction catalogues use “6611B” for several later examples.
