Antiquorum's 2026 catalogue identifies case 91535 as an Oyster Viceroy. Brown & Williamson's company history records Viceroy's 1936 introduction and says the company added a Viceroy coupon in 1937.

Rolex Oyster Junior Sport 2784, case 81218, double-signed for Beyer of Zurich

The 2784 is a small, manual-wind Oyster with a barrel-shaped case. Auction catalogues measure it at 30 or 31mm, with one 34mm outlier. They use the names Oyster Junior Sport, Oyster Lipton, Oyster Viceroy, Oyster Raleigh and Oyster Centregraph. Yorktime also documents an unsigned Solar Aqua dial in a case stamped 2784.

RolexForums reference lists and marketplace listings sometimes file the 2784 under Bubbleback or Oyster Perpetual. The auction records reviewed here describe manual movements; Sotheby's calls the Junior Sport a Flatback. That evidence places the documented watches among manual Oysters, though it does not settle the case profile of every example.

Where it sits in the line

One early Oyster case reference could carry several marketed names. Antiquorum notes that ref. 3116 appeared as Royal, Viceroy and Imperial, plus chronometer-labelled Imperial and Observatory variants. Ref. 2784 shows the same pattern in the auction record.

Sotheby's dates the reference to the early 1930s and describes the 31mm Junior Sport as a slimmer alternative to a standard Oyster. The name alone does not establish a formal size class.

David Boettcher's research on vintagewatchstraps.com, drawing on Swiss commercial-register extracts, shows that Montres Huître S.A., trading as Oyster Watch Limited, was incorporated in Geneva on 31 August 1928 with Hans Wilsdorf on its first board. It was legally separate from Rolex Watch Company, ceased trading in 1940 and was struck from the register in 1969. That corporate separation helps explain why Oyster Watch Co. and Rolex marks can appear together without making every component Rolex-manufactured.

Production outline

The catalogue estimates do not reconcile with the observed case-number order. Christie's dated cases 126541 and 127947 to circa 1930, while Sotheby's dated the lower case 92797 to circa 1939. Documented cases cluster around 81,000–93,000 and 126,000–128,000. The houses assign individual watches dates from circa 1930 to 1945, but those estimates do not establish a production range.

Antiquorum dates the steel-and-gold Oyster Raleigh, case 126474, to 1941 without explaining the basis for that date.

Caseback of a Rolex Oyster 2784 stamped with case number 126474 above the reference number 2784
Number 126474 is stamped above the reference, in the upper documented case-number band.


Movement notes

Auction catalogues describe manual movements with 15 or 17 jewels but give no maker or caliber name. David Boettcher documents the 10½-ligne Fontainemelon FHF 30 in Oyster Watch Co. watches and identifies Cal. 59, with a centre-seconds 59(SC) version, as Tudor designations. Ref. 2784 auction records leave the caliber unassigned.

An FHF 30 family attribution is plausible for ref. 2784 but not directly confirmed by the available movement photography. The only movement image tied to a case visibly stamped 2784 has a Tudor-signed bridge and may be a replacement. The Centregraph and Raleigh records establish centre seconds; their catalogues leave the caliber unnamed. Both 15- and 17-jewel movements remain documented; the reason for the split is unknown.

Canadian-market names and movement supply

Oyster-cased watches sold in Canada and the wider Commonwealth carried names including Raleigh, Commander, Recorda and Shipmate. Ref. 2784 appears under several of these names, but no source establishes what share of production went to Canada.

One account says the Aegler territorial agreement forced Rolex to use Fontainemelon movements in North America. Boettcher's commercial-register research instead places Canada inside Rolex's permitted British Empire territory and restricts Gruen to the United States. These sources do not establish why the Canadian-market examples used Fontainemelon movements.

Claims that Junior Sport was sold only in Canada, through military exchanges, or specifically to departing soldiers come from repeated dealer copy. Analog/Shift supports broader Commonwealth distribution and private military purchases; it does not tie those claims to ref. 2784.


The Viceroy and Lipton names

Antiquorum's 2026 catalogue identifies case 91535 as an Oyster Viceroy. Brown & Williamson's company history records Viceroy's 1936 introduction and says the company added a Viceroy coupon in 1937. That confirms the cigarette promotion existed; neither the catalogue nor the company history links this watch to it. Brown & Williamson's Raleigh coupon program is documented separately.

An NAWCC contributor suggested that Oyster Lipton referred to tea merchant Thomas Lipton and marked the idea as a belief. The Artcurial catalogue establishes the Lipton name on a watch catalogued as 2784B, but the material reviewed here does not establish why that name was used.

Dial map

Auction catalogues document nine named or otherwise distinct dial configurations below. The Solar Aqua is a separate photographed example tied to the reference by its inner caseback stamp. This is a record of sourced examples, not a complete factory dial list.

Dial Description Documented by
Silvered, luminous Arabic Subsidiary seconds and blued hands Christie's 2005 (case 126541)

The Centregraph has sweep centre seconds, unlike the subsidiary-seconds examples. Christie's catalogued one with 17 jewels and an inner red 24-hour chapter ring but did not name its caliber.

The Solar Aqua does not appear in the ref. 2784 auction record. A Yorktime listing pairs the unsigned Solar Aqua dial with an inner caseback visibly stamped 2784, direct photographic evidence tying the branch to this reference. The same watch has a Tudor-signed movement bridge, which may be a service replacement and is not used here to establish original movement branding.

A dealer description of an ordinary 3-6-9 luminous Arabic dial as an "Explorer dial" imports terminology from a reference two decades later, and the label should not be carried across. It is the standard silvered luminous Arabic configuration.

Case, bezel, crystal, and crown

The catalogued cases are barrel-shaped with screw-down backs and crowns. Christie's, Antiquorum and Artcurial give 30mm, Sotheby's gives 31mm, and Bonhams gives 34mm. Bonhams does not state how it measured the case, so the 34mm figure reads as an isolated outlier. It does not establish a second case size.

Auction catalogues describe plain and bevelled bezels. No production sequence has been established.

The photographed Solar Aqua inner back carries Oyster Watch Co., an RWC LTD oval and the reference 2784. Boettcher identifies RWC LTD as a British sponsor's mark; that falls short of proving Rolex made the case. His broader Oyster Watch Co. research discusses an SAR mark under a seven-pointed crown, but that mark is not visible on either ref. 2784 caseback image used here.

Boettcher records other references with Rolex Oyster dials and Oyster Watch Co. casebacks. He does not treat the combined marks as a settled guide to who manufactured each component.

Bracelets and straps

One example wears a Bonklip; others appear on leather straps. Christie's records a presentation box with case 127947. No bracelet or strap has been established as original delivery.

Auction record

Eleven sourced auction appearances across five houses are known. Ten have sale dates and appear below. The eleventh is Christie's sale 5650, lot 15, an Oyster Junior Sport with case 127947 and a presentation box; the surviving lot page gives no sale date or result.

Sale Date Name Case Result

Sotheby's, Fine Watches 8 2023 Oyster Junior Sport 92797 n/a
Antiquorum, Geneva 9 Nov 2024 Oyster Junior Sport, retailed by Beyer 81218 CHF 6,875
Antiquorum 9 May 2026 Oyster Viceroy 91535 USD 4,504
Antiquorum, Monaco 28 Jun 2026 Oyster Raleigh, steel and gold 126474 est. EUR 2,000–4,000

The highest individual-watch result in the sourced record is CHF 6,875 for the Beyer-retailed three-tone watch at Antiquorum in November 2024, against a CHF 2,000–4,000 estimate. The two Christie's totals belong to two-watch lots and cannot be assigned to ref. 2784 alone.

The Christie's 2005 lot pairs a 2784 Junior Sport with a separate plated Rolex Viceroy. The Viceroy in that lot is a separate companion watch; Antiquorum's May 2026 watch is the sound evidence for the Viceroy name on this reference. In the 2003 Christie's lot, the 2784 is the Centregraph and the companion is a Rolex Sky-Rocket.
