For [[Reference:1601|ref. 1601]], Phillips lists case number 926196 on a watch dated circa 1963. Sotheby’s records case 1,267,924 on a circa-1966 example, 3'835'110 on a circa-1974 watch, and 4'201'060 on a circa-1976 watch. Use these catalogue pairings to compare individual 1601s; the general serial chart remains an estimate and the pairings do not establish production years.

For ref. [[Reference:5052|5052]], Christie’s gives case 653977 and dates its pink-gold watch to the 1940s; Stockholms Auktionsverk records steel case serial 663654 with a 1950s estimate. These nearby numbers do not fix the watches to those decades: the numeric sequence was reused, and the published dates remain catalogue estimates. Anderson & Garland's 5052-attributed watch has only the prefix 663xxx, so it cannot be matched to case 663654 from the number alone.

For ref. [[Reference:8952|8952]], Sotheby’s dates case 351,427 circa 1952. Crescent Watch Guys' chart puts that number in both a mid-1940s pre-reset range and a late-1950s post-reset range. The chart is an estimate; keep Sotheby’s date attached to its catalogue entry.

The 6082 records show why catalogue dates need to stay attached to their watches: Gardiner Houlgate dates a ref. 6082 with serial masked as 69x to circa 1948–50; the masked number cannot calibrate the serial chart. Antiquorum dates case 784516 to 1951 and case 721396 to circa 1962; Monaco Legend dates case 810693 to 1951; Sotheby’s dates lower-numbered case 696848 to circa 1960. These estimates do not follow a consistent case-number sequence. Keep the catalogue dates attributed and do not use them to revise the generic serial chart.

For ref. [[Reference:6426|6426]], Antiquorum dates cases 614,731 and 615,217 to 1948, while the Pergola chart places both numbers in its reused 539,969–663,484 band marked 1960. Antiquorum separately dates case 502,000 to circa 1960. Phillips later dates letter-prefixed case R492,864 to circa 1987. Keep these as dates attached to individual watches; the conflicting numeric examples show why a serial estimate cannot replace the catalogue evidence.

For ref. [[Reference:5028|5028]], catalogue dates also resist a simple serial-year reading. Monaco Legend dates case 412191 to 1945, while Christie's gives circa 1946 for that watch and dates case 493076 to 1946; Christie's dates case 412032 to circa 1960. Monaco Legend dates case 411813 to 1958, while Antiquorum's 2002 catalogue places an unnumbered watch in the 1960s.

For early [[Reference:prince|Prince]], [[Reference:bubbleback|Bubbleback]] and manual Oyster references such as [[Reference:3478|3478]], compare the case number with examples of the same reference and material. A chart covering later Oyster production may not describe an earlier case-number sequence. British hallmarks on precious-metal cases provide a separate assay date. Steel cases need other evidence.

Ref. [[Reference:3068|3068]] illustrates the limits of its auction record: catalogues date individual watches from c.1935 to c.1950, while Sotheby’s and Antiquorum report different diameters and movement sizes for case 1008594. Antiquorum reads a Dublin import mark on case 1008656 as 1937. These object-level readings do not form a serial-year sequence or establish the reference’s production span.
For [[Reference:3346|ref. 3346]], Antiquorum dates case 146262 to circa 1937; Christie’s dates its 2002 example to circa 1938, and Sotheby’s later identifies that watch as case 142587. Monaco Legend dates case 142589 to circa 1941, while Sotheby’s dates case 146269 to circa 1942. The lower-numbered 142589 thus receives a later catalogue date than 146262. These are attributions to individual watches, not a serial-year sequence or production span.

For [[Reference:3462|ref. 3462]], Christie’s dates cases 161’489 and 161’501 to circa 1939. Loupe This later dates case 161’501 to circa 1942. The shared case number shows that both records concern one watch. Treat the dates as conflicting catalogue estimates; neither establishes a serial-year sequence or the reference’s production span.

For [[Reference:4364|ref. 4364]], auction catalogues attach dates from circa 1943 through circa 1948 to separate cases numbered 295355, 375096, 375110, 391849, 426783 and 685646. Treat these as catalogue estimates for those watches; they do not form a serial-year chart.

Auction and dealer records date individual 1504 watches: Phillips dates white-gold case 1,420,737 to circa 1966; Estates Consignments dates yellow-gold case 2,537,128 to 1970; Eguchi lists case serial 2714*** as 1971; The W3674 listing assigns its masked 27xxxx serial to 1972; EveryWatch preserves a yellow-gold auction description dated circa the 1970s for case 2,472,771. Sotheby’s 2019 catalogue repeats Phillips’s case 1,420,737, so it is the same watch, not another dated specimen. These are lot and dealer dates, not a serial-year chart or production limits.

=== Oyster Perpetual Date 1506 dated examples ===
Auction catalogues date ref. [[Reference:1506|1506]] case 1,117,252 to 1964, case 1,063,296 to circa 1965, and case 1,525,920 to 1967. The first two case numbers run opposite to their catalogue dates, so keep each date attached to its specific watch rather than treating these examples as a serial-year sequence. A seller-dated 1960 example has no visible case number in the available photographs. None of these records establishes the reference’s production span. [https://www.christies.com/lot/lot-5158504 Christie’s, case 1,117,252]; [https://jewelry.ha.com/itm/timepieces/wristwatch/rolex-fine-18k-oyster-perpetual-date-watch-with-chine-finish-ref-1506-circa-1965/a/5538-54133.s Heritage Auctions, case 1,063,296]; [https://catalog.antiquorum.swiss/en/lots/rolex-lot-206-127 Antiquorum, case 1,525,920]

Auction catalogues assign dates from circa 1962 to 1969 to individually numbered 1507 or 1503/1507 watches: case 928,501 (joint attribution) circa 1962; 1,144,916 circa 1964; 1,122,198 circa 1965; and 1,916,162 and 2,864,908 circa 1969. Sotheby’s’ circa-1964 estimate for 1,144,916 is later in the serial sequence than its circa-1965 estimate for 1,122,198. These estimates do not form a reliable serial chronology. A separate circa-1975 Christie's 1507 has no published case number.

Phillips re-listed the same Ricciardi watch in 2026 with case number 1,906,206, while movement, retailer mark, clasp stamp and paper dates match its 2019 record. Christie's dates serial 2,860,900 to circa 1971, while Gazette Drouot uses the same number for a hand-wound watch dated 1955–58. The conflicting movements and dates leave this serial unusable as a production boundary. Catalogue dates apply to individual watches; serial-number chronology remains unresolved.

=== Oyster Perpetual Date 1505 dated examples ===
Auction catalogues date ref. [[Reference:1505|1505]] examples from circa 1960 to circa 1980: Heritage assigns case 1,351,111 to circa 1960, but Pergola's unofficial serial chart places that number in its 1966 band. The date for that watch remains unresolved. Christie's records a separate circa-1969 example with an inside-caseback stamp II/69 and dates case 5,225,028 to 1977; Sotheby's dates cases 5,036,208 and 5,408,060 to circa 1977 and 1978; Christie's dates case 5,696,735 to circa 1980. Cambi dates a partial case 2,772.xxx to circa 1971, but its all-steel attribution conflicts with Rolex's 1980 catalogue description.

Ref. [[Reference:3078|3078]] shows why the case mark and watch date must stay separate. Christie's reports Dublin import marks dated 1937 on a 9ct-gold example but gives no case number. David Duggleby's caption reports Glasgow import marks dated 1937 and case markings read as 3789/3078; the number has not been independently confirmed. The records may describe the same watch.

Antiquorum’s 2010 description of [[Reference:971|Prince 971]] case 70,064 is inconsistent about the assay office.

Its date is an assay reading, not a movement-production date. Bonhams’ 2018 lot 37 separately identifies case 0329 with a Glasgow 1929 mark and movement 70,668.

The table lists catalogue observations on Prince watches and related Eaton presentation pieces. “c.” means an approximate date assigned by the auctioneer. Hallmark readings and presentation inscriptions are identified separately. These examples do not define the start or end of a reference's production. Christie’s, Bonhams, Piguet and Sotheby’s date four individual ref. 1855 cases from circa 1930 through circa 1940. Their published descriptions do not report a Glasgow or Edinburgh import mark, so those dates remain catalogue estimates for the watches; the numbers do not establish a production span. The Bonhams caseback also carries the parachute trademark David Boettcher attributes to Robert Meylan; his case-making company was registered in 1928 and the trademark in 1934. Those registration dates identify the maker’s marks, not the manufacture date of case 14368. Boettcher says the crowned SAR mark remains unexplained.

A Vintage Rolex Forum owner separately reports case 803027 and dates that watch to about 1951; this is an owner attribution, not an independently checked serial-year anchor.

For Datejust ref. [[Reference:16003|16003]], Kaplans dates case serial 5,230,455 to circa 1977. Morton assigns circa 1978 to 5,885,578, while Dorotheum dates the slightly lower case number 5,880,264 to circa 1979. Those close serials receive dates in reverse order, so the catalogue dates are approximate lot attributions rather than a serial-year sequence. Kaplans and Dorotheum list movement numbers separately from the case serial. See [https://www.kaplans.se/en/auktioner/3664?p=20 Kaplans, auction 385]; [https://www.bidsquare.com/online-auctions/morton-subastas/rolex-oyster-perpetual-datejust-steel-and-14k-yellow-gold-ref-16003-ca-1978-1613056 Morton, lot 134]; [https://www.dorotheum.com/en/l/1075885/ Dorotheum, lot 301-400018/0001].


A different reference stamped inside the caseback needs comparison with documented examples of that model. Assess the fit and markings together before accepting the back as original or period-correct.
