	Twenty-five ~~past~~ auction-lot ~~appearances~~ identify at least eighteen watches. ~~Dated sales in the set run~~ from 1995 to 2026; Christie’s circa-1935 lot has no verified sale date. The records cover three Antiquorum lots, twelve Bonhams lots, two David Lay lots, three Christie’s lots, one Sotheby’s lot from 2004, one Finarte lot, one Auctionet lot, one Dawsons lot and one Sotheby’s lot from 2026. Christie’s has a further 2765 scheduled for its Geneva online sale on 15 October 2026; that live listing is outside the past-lot count. Reoffers account for some of the total: Bonhams reoffered the Oyster Royal with a case number beginning 133 (remaining digits withheld) and Oyster Scientific cases 90,751 and 90,698; David Lay’s 2024 and 2025 lots and Sotheby’s 2026 lot show case 85,883. Other record identifiers include Dawsons serial 76,781; Auctionet case 90,995; Finarte case 14,277; Christie’s cases 83,259 and 83,447; and Bonhams serials 857 (remaining digits withheld), 90,509 and 140,782. Christie’s 1935 lot and Sotheby’s 2004 entry give no case number. Christie’s gives the scheduled lot a partly obscured case number, 14XX77. ~~It may be~~ Finarte case 14,277, so the ~~two records~~ do not ~~add another identified watch~~.		Twenty-five auction-lot entries identify at least eighteen watches. Recorded sale dates range from 1995 to 2026; Christie’s circa-1935 lot has no verified sale date. The records cover three Antiquorum lots, twelve Bonhams lots, two David Lay lots, three Christie’s lots, one Sotheby’s lot from 2004, one Finarte lot, one Auctionet lot, one Dawsons lot and one Sotheby’s lot from 2026.

Christie’s 1935 lot and Sotheby’s 2004 entry give no case number. Christie’s gives the scheduled lot a partly obscured case number, 14XX77. Finarte records case 14,277. Both listings name Randles Durban, but the visible numbers do not match; keep the watches separate unless a case-number match is established.

	The records identify individual examples rather than a production sequence. Their circa 1930–1942 dates apply to those watches; reference production limits need separate evidence.

	“Ultra Prima” identifies a movement grade. David Boettcher’s history of Rolex and Aegler movement grades dates Wilsdorf’s registration of the name to 9 December 1930 and notes that the distinction between Extra Prima and Ultra Prima is unclear. Antiquorum describes the Milan 2765 as a 17-jewel Ultra Prima.		“Ultra Prima” identifies a movement grade.

Antiquorum describes the Milan 2765 as a 17-jewel Ultra Prima.

	The examined ~~Antiquorum~~, ~~Bonhams~~, ~~Christie's~~, ~~Sotheby's and~~ David ~~Lay catalogues leave the caliber unnamed. Secondary~~ listings ~~assign Cal. 700;~~ the ~~available catalogue text and~~ movement ~~images provide no marking that verifies this attribution~~.		Cal. 700 appears in secondary listings. The examined auction catalogues and available movement photographs provide no confirming caliber marking. Sotheby’s 2026 catalogue calls case 85,883 an Oyster Perpetual in its promotional text, while its technical field says only “mechanical, jewelled.” David Lay’s two listings for the same case number specify an 18-jewel manual-wind Ultra Prima movement.

	The catalogue names include Oyster Chronometer or Chronomètre, Oyster Royal, Oyster Scientific, Oyster Gammeter and Observatory. Treat a name as dial text only where the photograph shows the lettering. Finarte’s title identifies case 14,277 as retailed by Randles Durban; its description does not transcribe the retailer signature. Christie’s scheduled October lot is a Randles Durban 2765 with a partly obscured number (14XX77), a silvered dial and a 33mm case; its condition report says two serial numbers are faded or missing. Finarte describes a cream dial and 32mm case for 14,277 and also attributes it to Randles Durban in the title. The retailer ~~and partial~~ number ~~suggest a possible~~ match~~, while the catalogue descriptions differ~~. Auctionet describes case 90,995 with an “unusual” Arabic-numeral dial. Dawsons calls case 76,781’s dial tropical; that description records the auctioneer’s wording, not a documented factory variant. An EveryWatch listing also uses “sector” for a 2765 dial. Identifying factory variants requires clear dial photographs and supporting records for each example. Secondary listings also use “Oyster Precision” and “Ultra Prima” as dial names. A 2765 photograph showing that wording would be needed to confirm either attribution.

	Christie’s has not published a result for the circa-1935 lot. The Geneva Online lot is scheduled for 15 October 2026; its ~~serial~~ number ~~may match~~ Finarte ~~case~~ 14,277.		Christie’s has not published a result for the circa-1935 lot. The Geneva Online lot is scheduled for 15 October 2026. Christie’s masks its number as 14XX77; Finarte records 14,277. Their shared Randles Durban attribution merits comparison, but the visible number strings, dial descriptions and stated sizes differ, so the records remain separate.

	The Hong Kong 2001 lot came with a fitted box and Antiquorum’s overall condition grade A (Good): case 4–6, movement 4–6*, dial 4–7–01. Antiquorum cited a similar watch in Osvaldo Patrizzi’s ''Rolex, Collecting Wristwatches'' (Guido Mondani Editore, Genova, 1998), page 278. The catalogue calls it a similar watch and gives no reference number; the cited page has not been checked directly.
