Two dealer records differ by a year from the 1962 Pergola band. HODINKEE dates 1022 case 856369 to 1963; LV800 dates case 856242 to circa 1963. Both numbers fall in the chart’s 1962 band. These are estimates for individual watches, not factory production dates. [https://shop.hodinkee.com/products/1963-rolex-oyster-perpetual-ref-1022-florentine-finish HODINKEE, case 856369]; [https://www.1stdibs.com/jewelry/watches/wrist-watches/rolex-mens-18k-rolex-oyster-perpetual-1022-automatic-c1963-swiss-vintage-lv800/id-j_9711082/ LV800 via 1stDibs, case 856242]; [https://rolexhaven.com/serial-numbers.html Pergola chart photograph].
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: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. [https://www.sothebys.com/buy/86de210f-86a9-4599-a8b9-bef3d3bfed75/lots/83afeb8b-1684-4fb2-9c38-0fe31a484dfe Sotheby’s, lot 8932]; [https://crescentwatchguys.com/pages/rolex-serial-numbers Crescent Watch Guys serial chart].
 
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. [https://auctions.gardinerhoulgate.co.uk/print-catalogue/354e86b2f2f64361e4c737fa8504bc4f/63b778f7668dabe928d3800924a99077/watches-jewellery-now-14th-may/ Gardiner Houlgate, lot 436] [https://catalog.antiquorum.swiss/en/lots/rolex-lot-108-12 Antiquorum, case 784516] [https://catalog.antiquorum.swiss/en/lots/rolex-ref-6082-oyster-lot-343-309 Antiquorum, case 721396] [https://www.monacolegendauctions.com/index.php/auction/exclusive-timepieces-32/lot-162 Monaco Legend, case 810693] [https://www.sothebys.com/en/buy/auction/2022/fine-watches-2/reference-6082-oyster-precision-a-stainless-steel Sotheby’s, case 696848]
 
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. These are estimates or catalogue attributions for individual watches, not a reference-specific serial chart.

For ref. [[Reference:5056|5056]], catalogues report cases 628830, 629518 and 630309. Christie’s dates the certificate for movement 4237 to 20 July 1948; Bonhams dates movement 4215’s Kew pass to 24 June 1947 but gives the same case 629518 both circa 1947 and circa 1961; Monaco Legend dates case 630309 to 1949. The test date belongs to the movement, and the lot estimates do not establish a serial-year sequence or production span.

For ref. [[Reference:5006|5006]], published dates attach to individual watches: EBTH estimates a serial-masked steel example at 1948, TimeAnagram dates a masked “65++++” steel example to 1949, Antiquorum dates case 671819 to the early 1950s, and Finarte describes case 700389 as a 1950s watch. These are catalogue dates, not a serial-year sequence or a production span.

For ref. [[Reference:5010|5010]], Antiquorum dates case 646'799 to 1948; The Auction Room estimates case 655756 at circa 1949; Phillips dates case 655'677 to 1950; Bonhams describes case 35873, stamped II.55 inside, as circa 1955. These catalogue observations place individual watches across the decade; they do not form a reference-specific serial chart.

A 1stDibs item description gives a partial serial, 529,xxx, for a claimed ref. 1010 and dates it circa 1960; the page title says ref. 1011. The number falls in Pergola’s 1959 range. Its missing digits do not show whether it is Dowling–Hess’s exact 529,163 entry.

For ref. [[Reference:5003|5003]], Christie’s dates case 724279 to circa 1951 and Antiquorum dates case 849609 to circa 1953. Antiquorum assigns a circa-1960s date to the lower-numbered case 565407. The catalogue estimates do not follow a clear sequence. They belong to individual sale records and do not form a generic serial chart. [https://www.christies.com/en/lot/lot-5643871 Christie’s, case 724279] [https://catalog.antiquorum.swiss/en/lots/rolex-ref-5003-oyster-perpetual-lot-359-125 Antiquorum, case 849609] [https://catalog.antiquorum.swiss/en/lots/rolex-ref-5003-oyster-perpetual-super-precision-lot-343-324 Antiquorum, case 565407]


Early chronograph catalogues also show why an individual case number needs its own evidence. Christie’s dated Rolex ref. 2021 case 12'010 to circa 1925; Phillips later catalogued the same case as a 1934 watch. These are conflicting auction estimates, not a serial-chart date or a confirmed production year. [https://www.christies.com/en/lot/lot-4596639 Christie’s, case 12'010] [https://www.phillips.com/detail/rolex/115419 Phillips, case 12'010]
Doyle dates one ref. [[Reference:5013|5013]] with partial case serial 58664 to the 1940s. Linckersdorff dates a separate gold example to 1940–49; Curious Curio and Cool Auction give late-1940s or circa-1949 dates to their listings. None of these records supplies a serial sequence for the reference. The partial number and catalogue dates belong to individual watches.

Ref. [[Reference:2303|2303]] predates the later Oyster serial charts. For a gold example, use British assay marks when present; the [[#Glasgow_and_Edinburgh_assay_marks|Glasgow and Edinburgh method]] dates the case’s assay, which can precede movement fitting or sale. Both catalogues describe case 021187 as steel and give catalogue dates: Christie’s says circa 1928; Antiquorum says the 1930s. [https://www.christies.com/en/lot/lot-5674766 Christie’s, case 021187] [https://catalog.antiquorum.swiss/en/lots/rolex-lot-111-95 Antiquorum, case 021187]
The ref. [[Reference:6210|6210]] article lists five-digit case numbers with the individual sale records. James Dowling reported case 97458 from a Rolex letter. These records do not connect the 6210 numbers to the generic serial charts. [https://www.hodinkee.com/articles/the-rolex-kew-a-quite-possibly-and-very-likely-the-most-accurate-vintage-rolexes-ever-made Hodinkee on Dowling’s report]


For early Oyster ref. 2081, Antiquorum links case 599744 to its 1947 catalogue date and case 63715 to its 1948 date; Christie’s records case 37'271 with a Glasgow import letter for 1937. Toovey’s transcribes “5557 CH” over “2081” on another caseback. These remain individual object records rather than entries in a year chart. [https://catalog.antiquorum.swiss/en/lots/rolex-lot-108-226 Antiquorum, case 599744] [https://catalog.antiquorum.swiss/en/lots/rolex-lot-203-675 Antiquorum, case 63715] [https://www.christies.com/en/lot/lot-5130485 Christie’s, case 37'271] [https://www.tooveys.com/lots/536665/a-rolex-oyster-chrome-plated-cushion-cased-gentlemans-wristwatch Toovey’s, caseback inscription]
Two dealer records differ by a year from the 1962 Pergola band. HODINKEE dates 1022 case 856369 to 1963; LV800 dates case 856242 to circa 1963. Both numbers fall in the chart’s 1962 band. These are estimates for individual watches, not factory production dates.

Ref. 2280 auction catalogues associate case 81,877 with circa 1936, case 77585 with circa 1940, 153,193 with 1939, 130’527 with circa 1941, and cases 159,151 and 217’903 with circa 1942. Toovey’s photographs 159151 over the reference number. These are dates assigned to separate watches by their cataloguers; they do not establish a serial sequence or production-year boundaries.

Ref. [[Reference:1023|1023]] shows the same limits. ART Jewellery & Watches lists 1023/9 and 1023/83 for 1964–1971 but gives no basis for those dates. Waddington’s dates serial 902827 to circa 1964, while Pergola places it in the 1962 band. Gardiner Houlgate dates partial serial 1136xxx to circa 1964; the partial number cannot be checked precisely against a serial chart. Hess catalogues case 1,382,519 as circa 1966, matching Pergola’s 1966 band, though the photographed guarantee appears dated 1/6/68. Watch.de dates a 2,186xxx example to 1969, within Pergola’s 1969 band; Kaplans lists serial 2,186,841 with the same approximate date. Watch.de masks its number as 2186xxx, so the exact serial match cannot be checked; the shared case number and other listing details suggest a repeat appearance. Heritage catalogues serial 933953 as circa 1986, a date that conflicts with the ART guide and ordinary serial-chart estimates; the record is not enough to extend the reference into the 1980s. These catalogue dates and unofficial chart bands apply to individual cases, not the reference’s production span.

Early chronograph catalogues also show why an individual case number needs its own evidence. Christie’s dated Rolex ref. 2021 case 12'010 to circa 1925; Phillips later catalogued the same case as a 1934 watch. These are conflicting auction estimates, not a serial-chart date or a confirmed production year.

=== Conflicting catalogue dates: reference 6244 ===


Catalogue dates differ even for nearby case numbers on the [[Reference:6244|Oyster Royal 6244]]. [https://www.phillips.com/detail/rolex/96544 Phillips dates case 834,991 to 1952]. Christie's gives [https://www.christies.com/en/lot/lot-5731475 circa 1959 for case 836,438] and [https://www.christies.com/en/lot/lot-5158176 1962 for case 836,447], only nine numbers apart. These catalogue dates do not establish a continuous production sequence. The reference page lists further examples.
Catalogues date ref. [[Reference:2226|2226]] case 1004619 to circa 1920, cases 1004626 and 1005651 to circa 1925, and case 1004623 to circa 1940. These dates belong to the individual lots; the cases do not establish a serial-year sequence or the reference’s production limits.

Reference 6548 catalogues give separate dates for individual watches: Dorotheum dates serial 230584 to circa 1942/43; Sotheby’s dates case 312’326 to circa 1945; Cambi dates case 324.xxx to circa 1957; and Pandolfini dates serial 22351xx to 1969. These estimates do not establish a serial-year key or production sequence.

Ref. [[Reference:5002|5002]] catalogues date individual cases to circa 1945 (614945), circa 1948 (689220), circa 1949 (Christie's example, caseback stamped 5002), circa 1950 (848921), and circa 1952 (848950).

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.

Those are estimates for individual watches, not a dependable case-number sequence. The reviewed 3540 examples provide no assay-mark date.

Ref. [[Reference:1925|1925]] shows why patent marks and case numbers need separate treatment. Christie’s lists case 25658 with Glasgow import marks dated 1928. Bonhams records a Dublin import mark for 1928 and labels 260554 a case number. The British Museum transcribes 260554/1925 below “Great Britain Patents” on another early Oyster case; that object is not identified as ref. 1925. Christie’s separately prints “20302/260554” as its circa-1925 lot number. The museum’s patent inscription shows why catalogue numbers should stay attached to their recorded markings rather than being normalized as serials. The import marks provide dates for the individual cases.  
Ref. [[Reference:1925|1925]] shows why patent marks and case numbers need separate treatment. Christie’s lists case 25658 with Glasgow import marks dated 1928. Bonhams records a Dublin import mark dated 1928 and calls 260554 a case number. The British Museum transcribes 260554/1925 beneath “Great Britain Patents” on another early Oyster case; that object is not identified as ref. 1925. British patent GB260554A concerns a screw-threaded winding crown and has a listed priority date of 30 October 1925. Christie’s also prints “20302/260554” for its circa-1925 watch. Keep the catalogue numbers tied to those entries; the available records do not verify either field as a case serial. The import marks record the cases' entry into Britain and Ireland in 1928.

Ref. [[Reference:1936|1936]] supplies another set of early case records. Bonhams lists Glasgow import marks for 1933 and 1934; Dore & Rees records one for 1937 on case 35894. Christie's case 15055 may match Bonhams case 150**, so those records are not secure separate watches.

Ref. [[Reference:1936|1936]] has dated case records from Bonhams and Dore & Rees. Bonhams gives Glasgow import marks for 1933 on case 10065 and 1934 on cases 150** and 15796; Dore & Rees records a 1937 mark on case 35894. Olde Timers reports Glasgow hallmarks dated 1938 on a ref. 1936 listing, but provides no full case number, leaving its identity relative to Bonhams case 150** unresolved. Bonhams' 2015 case 15796 is identified by its full number, distinct from the masked 150** record.

Catalogue dates for three [[Reference:4643|ref. 4643]] watches show why each estimate belongs to its case: Antiquorum dates case 641390 to 1948 ([https://catalog.antiquorum.swiss/en/lots/rolex-lot-108-5 2006 Geneva lot 5]); Christie’s dates case 568342 to circa 1950 ([https://www.christies.com/en/lot/lot-4211171 2003 London lot 97]); another Christie’s watch, case 824707, is dated 1952 ([https://www.christies.com/en/lot/lot-5612415 2012 Geneva lot 204]). These catalogue estimates do not form a continuous serial sequence. A Glasgow or Edinburgh assay mark on an example that may predate 1948 can help date the case; it remains separate from the watch’s assembly or delivery.
Catalogue dates for [[Reference:4643|ref. 4643]] cases remain lot-level estimates. Antiquorum dates case 641390 to 1948 ([https://catalog.antiquorum.swiss/en/lots/rolex-lot-108-5 2006 Geneva lot 5]). Dorotheum dates case 568321 to circa 1950 ([https://www.dorotheum.com/de/l/3266729/ 2014 Vienna lot 3266729]); Christie’s gives the same estimate for case 568342, 21 numbers later ([https://www.christies.com/en/lot/lot-4211171 2003 London lot 97]). Christie’s dates case 824707 to 1952 ([https://www.christies.com/en/lot/lot-5612415 2012 Geneva lot 204]). The nearby cases share an approximate catalogue date, but these records do not form a serial-year sequence. A Glasgow or Edinburgh assay mark on an example that may predate 1948 can help date the case; it remains separate from the watch’s assembly or delivery.

=== Oyster Perpetual 1025 dated examples ===
Meticulous Watches dates a ref. 1025 with partial serial 673XXX to circa 1961. The Pergola chart places 663485–688766 in 1960/61; the Swiss Watch Time chart assigns 673,600 to 1950. Rolex restarted its numeric sequence in the mid-1950s, and the chart sources do not agree, so the partial serial cannot settle the date. Freeman's and Hindman dates serial 947479 to circa 1963; Aste Bolaffi dates 1,812,604 to circa 1968; Antiquorum gives a late-1960s estimate without a serial. L o'clock lists serial 960962 as a 1960s example. Vintage & Prestige dates partial serial 401*** to 1974, though the published charts place that number in much earlier bands. Antiquorum's 2011 date-display catalogue attribution and Christie's circa-1973 solid-gold attribution have no readable reference marks in the available photographs. Those dates belong to the disputed catalogue attributions; they do not establish the 1025's production span.

Monaco Legend identifies case 36701 as a 6502; Phillips calls it a 6603 and reports a 6502 stamp inside the back. The conflicting catalogue attributions leave that watch’s reference unresolved.

Auction catalogues date 6511 case 111,654 to the fourth quarter of 1955 and case 134,692 to 1955; Phillips lot 40 lists a guarantee dated 7 May 1957. Monaco Legend lists case 111,695 as 1955, although the lot prose says 1956, and gives 1956 for case 166,725. These lot dates do not create a production range or a serial-year chart. Check the case number and any hallmarks on the watch, and keep bracelet/clasp dates separate from the head. The cited sources also disagree on movement identification: Phillips gives 1555 for case 111,654, while other 6511 catalogues list 1055.

Dorotheum dates case 166736 to the model period 1956–57, but its 2017 listing dates case 166744 circa 1965. Pergola's unofficial chart puts 166744 in its 1956 band. The photograph offers no readable case number, leaving the catalogue estimate and chart in conflict. Treat these as lot-specific estimates; together they do not set a production range or serial-year chart. The two catalogues listing Cal. 1555 for cases 111,654 and 166736 conflict with six other located 6511 lots listing 1055. Each remains a catalogue attribution pending direct movement inspection.

Antiquorum describes [[Reference:971|Prince 971]] case 70,064 as sterling silver with a [https://catalog.antiquorum.swiss/en/lots/rolex-lot-226-401 Glasgow import stamp and a 1928 hallmark]. The date is the auctioneer's reading of the hallmark; it does not establish when the movement was made or fitted.
Antiquorum’s 2010 description of [[Reference:971|Prince 971]] case 70,064 is inconsistent about the assay office. The lot introduction says English import hallmark dated 1928; the detailed case description says “Glasgow import stamp.” The catalogue does not resolve that discrepancy. 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.

For the Oyster Perpetual ref. 1013, a Rago Arts & Auction Center lot dated serial 1,900,046 to 1969. Pergola's unofficial serial chart places that number in its 1968 range. These are conflicting estimates for one watch; neither establishes a production-year boundary for the reference. [https://www.ragoarts.com/auctions/2022/02/interesting-timepieces/508 Rago lot 508]; [https://rolexhaven.com/serial-numbers.html Pergola serial chart].
For Oyster Perpetual ref. [[Reference:1014|1014]], Bonhams dates a gold-plated steel watch with masked case number 769*** to circa 1951. Bellmans later records serial 769199 and dates that watch to 1962; the masked number could match, but the catalogues do not confirm one object. Pergola's chart places 769199 in its 1961 band. The photographed Dowling–Hess chart lists 710,776 in 1951 and 840,396 in 1952, but does not list 769199, so it gives no direct date for this case. These are lot and chart attributions, not a production span.

For Cellini-labelled ref. [[Reference:3735|3735]], Fortuna dates case serial 1,809,871 to circa 1968; the number falls within Pergola's 1968 band (1,720,977–1,938,064). This agreement applies to one case. Farsetti dates its example to 1967 but masks the serial as 15**30, leaving no complete number for comparison.

Phillips reports that the last of these has an inner caseback stamp reading II.1958. These are auction dates for individual watches, not factory production endpoints. Antiquorum dates case 447,272 to circa 1966, but the chart above places that number in Pergola’s 1959 band (437,255–530,168). Treat the catalogue date as a conflict; serial charts are estimates and do not date the 6609 production run.

=== Day-Date 1803 dating ===
For the [[Reference:1803|Day-Date 1803]], use the general serial chart as an approximate case-date guide. Published histories give overlapping ranges: Monochrome dates the reference to 1959–1976, while Fratello and Sotheby’s place its introduction around 1960 and its transition to the 18038 in 1978. The caliber changed from 1555 to 1556 around 1965; Fratello and Monochrome date hacking seconds to 1972. Treat the case and movement as separate dates; inspect the movement and service history to identify the fitted caliber and whether hacking is present. See [https://monochrome-watches.com/history-rolex-day-date-1956-present-president-watch-in-depth-review/ Monochrome], [https://www.fratellowatches.com/rolex-day-date-historical-overview-of-rolexs-flagship/ Fratello], and [https://www.sothebys.com/en/articles/the-rolex-day-date-a-complete-collectors-guide Sotheby’s].

For ref. [[Reference:3358|3358]], Antiquorum dates case 51,419 to 1942, while the chart transcribed above brackets that number between its 1935 and 1940 entries. Auctionata dates case 299,752 to circa 1940. These are catalogue attributions, not a production range; the serial chart is a reconstruction and its entries are selective. For an imported pre-1948 case, date a Glasgow or Edinburgh assay mark by that office's own sequence where one is present; use the serial chart as a cross-check. The two 3358 catalogues do not report assay marks.

For ref. [[Reference:3716|3716]], catalogue dates vary by example. Antiquorum dates its unnumbered 1989 lot to the 1950s. Christie’s dates case 54524 to circa 1945, while Monaco Legend dates the same case to 1942; the repeated case is one watch, not two. Other catalogues date examples to circa 1940 and circa 1943. Heritage records a December 1946 dedication on case 56420; that dates the inscription, not manufacture. Accademia Fine Art prints serial 46.742, but the published serial charts do not establish a year for it. Keep these dates with their individual catalogue records.
