	Auction catalogues identify ref. 3540 as a manual-wind Rolex Precision in round steel and gold cases. Sotheby's describes 18 jewels for case 58,753; Heritage reports 15 for case 414,638, and Christie's gives 17 for another example.

These are specimen dates, not a continuous production record or firm endpoints. None of the reviewed records names a numeric caliber. Bernardini Milano dates its 35 mm steel example to 1954.

			Auction records identify the manual-wind 8952 as a central-seconds Precision and date separate examples circa 1952, 1955, 1956 and 1968. Phillips gives circa 1945 for another example and assigns it Cal. 1210, earlier than the Field Manual’s 1954–1964 range for that caliber. Crescent Watch Guys' chart places the Sotheby’s circa-1952 case number in both pre-reset and post-reset ranges. Some collectors call the 8952 Metropolitan; the name is not a Rolex designation.

	A Precision dial does not document an official chronometer certificate. Case construction and warranty terms still need to be read from the individual watch and its period papers; the grade word alone does not establish that the case, movement, or paperwork are original.		A Precision dial does not document an official chronometer certificate. Case construction and warranty terms still need to be read from the individual watch and its period papers; the grade word alone does not establish that the case, movement, or paperwork are original.

	The relationship between grade text and actual adjustment is looser than the vocabulary suggests. The Air-King 6552 runs a Cal. 1030 adjusted to chronometer standard and still reads Super Precision on the dial. Marcus Siems puts the distinction plainly: "in contrast to other Oyster Perpetuals these Air-Kings weren't Chronometer certified and marked Super Precision." The ~~words describe what Rolex was willing to certify and sell, and~~ the ~~certification~~ is ~~what the buyer paid for~~.		The relationship between grade text and actual adjustment is looser than the vocabulary suggests. The Air-King 6552 runs a Cal. 1030 adjusted to chronometer standard and still reads Super Precision on the dial. Marcus Siems puts the distinction plainly: "in contrast to other Oyster Perpetuals these Air-Kings weren't Chronometer certified and marked Super Precision." The dial wording records the grade designation used for that watch. It does not replace a period certificate or prove that the present movement is original.

The small manual-wind Oysters below appear in the Precision-era record through the 1930s and 1940s. Several use a Rolex sub-brand name on the dial instead of the grade word. The 4220 is explicitly linked to the Precision line in the cited catalogues. Their cases and calibers vary, and the examples listed here are not documented as chronometer-certified. The [[Reference:bubbleback\|Oyster & Bubbleback]] hub carries the same references inside the full 1926–1953 Oyster chronology.

	The Air-King ~~is where~~ the ~~designation ran longest and where~~ the ~~two grades are easiest to date~~. The ~~Air-King sequence~~ shows both ~~wording and caliber changes~~. Early hand-wound examples carry PRECISION; early automatic examples commonly carry SUPER PRECISION; later examples may read PRECISION or omit the grade line.

The Air-King provides a long sequence in which the dial wording changes with the caliber generations. The surviving record shows both grades, plus later dials with no grade line. Early hand-wound examples carry PRECISION; early automatic examples commonly carry SUPER PRECISION; later examples may read PRECISION or omit the grade line. The pairing is a dating clue, not a complete authentication test, because service dials and movements can be mixed.
