	Auction catalogues do not use one movement label consistently. Phillips lists caliber 1055 in its 1958 platinum 6612. Bonhams lists 1055 in a circa-1959 gold 6612/8. Monaco Legend also lists 1055 for its 6612B examples, while some other catalogues use B1055 or 1055B. The standard caliber registry groups the later chronometer-grade movement under 1055B, but the lot descriptions do not show whether each watch retains its original movement. See [[Reference:Movements]] for the broader 1055 record.		Auction catalogues do not use one movement label consistently. Phillips lists caliber 1055 in its 1958 platinum 6612. Bonhams lists 1055 in a circa-1959 gold 6612/8. Monaco Legend also lists 1055 for its 6612B examples, while some other catalogues use B1055 or 1055B. Christie’s Dubai lot 65 lists B1055 on a platinum watch whose caseback is stamped 6612 and 6613; the catalogue says earlier Phillips and Sotheby’s entries gave the wrong case number. The standard caliber registry groups the later chronometer-grade movement under 1055B, but the lot descriptions do not show whether each watch retains its original movement. See [[Reference:Movements]] for the broader 1055 record.

	For an individual watch, record the caliber as engraved or as documented by the source, and keep the suffix in that source's wording. The available catalogues do not support claims that every 6612 has a 1055B, that the date changes at exactly midnight, or that a particular movement label alone proves a production date.

	The ~~cited~~ catalogues give 36mm for ~~6612~~ examples ~~and~~ describe a smooth ~~bezel~~. Phillips identifies plastic crystal on case 403,680.

The catalogues report case diameters from 35 to 36mm: Bonhams gives 35mm for its yellow-gold 6612/8, while Phillips, Monaco Legend and Christie’s give 36mm for other examples. They describe smooth bezels. Phillips identifies a plastic crystal on case 403,680, and Bonhams describes a screw-down Oyster crown and caseback on the 6612/8. These records do not establish a single measurement or complete case specification for every watch.

	Materials in the records include yellow gold, white gold and platinum. The platinum examples have different case numbers: Phillips's case 403,680 and Monaco Legend's case 403,679 form a consecutive pair; Christie's separately catalogued platinum case 382,921. Phillips called the 403,680 watch one of two platinum examples known in 2015. That historical count should not be repeated as a current census in light of later catalogued examples.

	Several auction records document platinum 6612-family watches, with different case numbers and dials. Phillips's 2015 lot 43 is case 403,680, dated 1958, with a grey diamond-set dial. Monaco Legend's 2024 lot 67 is case 403,679, also dated 1958, with Eastern Arabic calendar discs and a tessellated bracelet. Christie's catalogued case 382,921 as a circa-1958 6612/B with a black baguette-diamond dial. The catalogues use 6612, 6612B and 6612/B; they do not establish whether those forms represent distinct factory references.

			===Case stamped 6612 and 6613===

			Christie’s Dubai catalogue describes a platinum watch as 6612B, with “6612” and “6613” stamped inside the caseback. It notes that Phillips and Sotheby’s had previously catalogued the watch with an incorrect case number. Phillips’s Geneva Watch Auction XIII also describes a separate case with both 6612 and 6613 markings and interprets the 6613 stamp as a later bezel change. These are catalogue interpretations of specific watches; they do not establish a factory 6612/6613 sub-reference.

	The 6612 is the smooth-bezel member of the Day-Date's second-generation cluster. It arrived in 1957 alongside the fluted [[Reference:6611\|6611]] and the diamond-bezel 6613, about a year after the [[Reference:6510\|6510]] and [[Reference:6511\|6511]] originals, and it carries the same three upgrades that turned the Day-Date into the President: the President bracelet, the "Superlative Chronometer Officially Certified" dial line, and the rebuilt caliber 1055 with a free-sprung Microstella balance. Where the 6611 wears the fluted "Millerighe" bezel, the 6612 wears a plain polished one. That is the whole difference between them.

	The shared origin story — the day-disc patents, the Presidential nickname, the full cluster roster — belongs to the [[Reference:6510\|6510]] entry, and the bracelet-and-caliber bundle that defines the cluster is set out on the [[Reference:6611\|6611]].
