Christie's, Antiquorum and Artcurial all give 30mm, Sotheby's gives 31mm, and Bonhams alone gives 34mm.

The true case is about 30–31mm, roughly 39mm lug to lug, and the residual 30-versus-31 disagreement is measurement slop between houses rather than two case sizes.

What makes it worth a page is the names on it. The same reference has been catalogued at auction as Oyster Junior Sport, Oyster Lipton, Oyster Viceroy, Oyster Raleigh and Oyster Centregraph.

	The 2784 does not use an Aegler movement, which sets it apart from the Rolex Oysters it resembles. Boettcher examined an Oyster Watch Co. movement directly and identified it: a 10½-ligne FHF 30 from Fontainemelon, running at 18,000 vph with fifteen jewels and a Swiss straight-line lever escapement. The same ébauche was used by Tudor as calibre 59, with a centre-seconds version designated 59(SC) and a Fontainemelon reference of FHF 30-1. That centre-seconds variant is what runs the Centregraph and the other sweep-seconds examples of this reference.		The 2784 does not use an Aegler movement, which sets it apart from the Rolex Oysters it resembles. Boettcher examined an Oyster Watch Co. movement directly and identified it: a 10½-ligne FHF 30 from Fontainemelon, running at 18,000 vph with fifteen jewels and a Swiss straight-line lever escapement. The same ébauche was used by Tudor as calibre 59, with an indirect centre-seconds version designated 59(SC) and a Fontainemelon reference of FHF 30-1. That centre-seconds variant is what runs the Centregraph and the other sweep-seconds examples of this reference.

	The "Font 59" and "font 59 caliber" phrases that appear in dealer copy and forum posts are not garbled: "Font" is Fontainemelon, and the movement is the calibre 59.		The "Font 59" and "font 59 caliber" phrases that appear in dealer copy and forum posts are not garbled: "Font" is Fontainemelon, and the movement is the calibre 59.

	Both 15- and 17-jewel movements appear across documented 2784 lots. No source explains ~~what drives the split~~, whether date, dial type or the centre-seconds ~~variant~~.		Both 15- and 17-jewel movements appear across documented 2784 lots. Boettcher accounts for the split at the ébauche: Fontainemelon also built the FHF 30 as a 17-jewel variant with end stones on the escape-wheel bearings. What no source explains is which 2784s got which, or whether the choice tracked date, dial type or the centre-seconds version.

	Boettcher~~'s assessment of~~ the movement ~~is unflattering. There is~~, ~~he writes~~, ~~not a lot of obvious difference~~ in ~~specification between fully jewelled Fontainemelon and~~ Aegler movements~~; the difference~~ is ~~that Rolex movements were carefully adjusted for timekeeping~~, ~~which~~ a ~~Fontainemelon ébauche like this one would not have been~~. The Oyster ~~Watch Co. watches were built to a price~~, and the movement ~~is where the price was met~~.		Boettcher rates the ébauche higher than its reputation. He calls the FHF 30 a good quality basic mass-produced movement, perhaps a little cheaper than an Aegler ébauche because Fontainemelon made them in volume, but similar in quality to Aegler's own fifteen-jewel movements. The example he examined is stamped "unadjusted", a mark applied to lower the import duty on watches sent to America rather than a verdict on the movement. The same NAWCC contributor put it more precisely: the six-position-adjusted chronometer movements of the period never went into an Oyster, and there is "nothing wrong with the Oyster movement."

	One authentication detail follows from the construction. On these ~~calibre 59 movements~~ the ~~Rolex signature sits under~~ the ~~dial instead of~~ on the bridge~~, reported independently~~ in ~~two places~~, ~~which makes an unsigned~~ top plate normal on this family.		One authentication detail follows from the construction. Fontainemelon delivered these ébauches unbranded, and the only change Boettcher records on the Tudor version is the name engraved on the bridge during manufacture. The owner of one in the 2003 NAWCC thread described his as completely unsigned, marked only "Swiss made" and "15 Rubies # 59". A blank top plate is normal on this family.

	Boettcher's version of the same agreement breaks that logic. He describes Rolex's permitted territory as running "throughout Europe, Asia and the British Empire, which included Australia and Canada," with Gruen restricted to the USA alone. If Canada was inside Rolex's Aegler territory, the Gruen agreement cannot explain why Canadian-market Oysters got FHF movements. Boettcher independently places the Fontainemelon workaround in the United States instead, in the Abercrombie & Fitch venture, where a cheap chrome-plated Oyster case was paired with a Fontainemelon movement.

	The distribution story that surrounds these watches needs the same scepticism. A paragraph asserting that the Junior Sport was sold only in Canada, marketed to soldiers heading overseas and sold through PX stores, circulates nearly verbatim across several dealer sites, and one copy still carries an un-edited reference to a different model. Editorial coverage supports only the general pattern, that Oyster-cased models were sold throughout Commonwealth countries and bought by individual servicemen. The specific claims about this reference rest on recycled listing copy.		The distribution story that surrounds these watches needs the same scepticism.

Both names have an origin story in circulation. One collapses under checking; the other is honestly labelled as a guess by the person who proposed it.

	The Viceroy story is that Rolex made the watch for a promotion by the Viceroy cigarette brand, redeemable with coupons plus cash at official dealers. It traces to two dealer listings with near-identical wording and appears in no auction catalogue, book or period document. ~~It also fails on~~ dates: Brown & Williamson introduced Viceroy cigarettes in ~~May~~ 1936, and the ~~New York Times describes~~ the ~~company as having been in~~ the ~~filter field "since 1936 when~~ it ~~brought~~ out ~~Viceroys~~." Rolex ~~Oyster Viceroy watches are catalogued from around 1933. A watch cannot be named after a cigarette launched three years later~~. The ~~same newspaper~~ account ~~notes that~~ Brown & Williamson's pre-war coupon programme ran on Raleigh, not Viceroy, which is probably where the confusion started, since Oyster Raleigh is also a real Rolex dial name.		The Viceroy story is that Rolex made the watch for a promotion by the Viceroy cigarette brand, redeemable with coupons plus cash at official dealers. It traces to two dealer listings with near-identical wording and appears in no auction catalogue, book or period document. The dates do not settle it. Brown & Williamson introduced Viceroy cigarettes in 1936, and the catalogued Rolex Viceroys run later still: Antiquorum's Mondani Collection lot on reference 3116, the reference sold under the Viceroy name among others, is dated 1940, and other catalogued examples fall between the late 1930s and the mid-1940s. Chronology leaves the promotion possible. What rules it out is where the name came from. Viceroy is one of Rolex's own model names, sitting on reference 3116 in the same Empire-titled set as Royal and Imperial, and owing nothing to tobacco. The New York Times account of Brown & Williamson adds that the company's pre-war coupon programme ran on Raleigh, not Viceroy, which is probably where the confusion started, since Oyster Raleigh is also a real Rolex dial name.

	There is a further reason to distrust that listing copy. The same page explains that "Prima simply means first, and this term was common use before Rolex was founded, as was extra Prima, which was used to mean high quality" — a sentence lifted almost word for word from Boettcher, who wrote that "Prima simply means first, and this term was in common use before Rolex was founded, as was extra prima, which was used to mean high quality." Having borrowed the sentence, the listing then attaches Extra Prima to the promotion. Extra Prima is a movement timekeeping grade with nothing to do with any marketing campaign.

	The Lipton name is handled more honestly by the person who proposed its origin. On the NAWCC board, a long-standing member offers it explicitly as belief rather than documentation: that the model was named for Sir Thomas Lipton of the tea company, famous for his America's Cup challenges, and that every example he has seen is an Oyster Lipton rather than a Rolex Lipton. A yachtsman is a plausible namesake for a waterproof watch, and it fits the wider Empire-themed naming set. No tea-coupon programme has surfaced in any source.

	The "Junior" in Junior Sport is a size class.

Sotheby's dates the reference's introduction to the early 1930s.

	Where the 2784 sits is best understood through the company that made the case. The horological researcher David Boettcher, working from Swiss commercial-register extracts, establishes that Montres Huître S.A., trading in English as Oyster Watch Limited, was incorporated in Geneva on 31 August 1928 with Hans Wilsdorf on the first board. ~~His conclusion is the one that matters: this~~ made Oyster Watch Limited "legally a completely separate company from the Rolex Watch Company and not just another sub-brand." It ceased trading on 28 August 1940 and was struck from the register in December 1969. James Dowling's ''Rolex: The Unauthorised History'' is explicit that Oyster Watch Co. products were not intended to compete with Rolex.

	The catalogue estimates do not reconcile. Christie's dated cases 126541 and 127947 both to circa 1930, while Sotheby's dated the much lower case 92797 to circa 1939. Higher case numbers cannot be nine years earlier. The documented cases fall into two bands, roughly 81,000 to 93,000 and 126,000 to 128,000, and the houses have variously assigned examples across those bands to 1930, 1935, 1936, 1939, 1940 and 1945. The case-number bands are evidence; the circa dates are guesses, and quoting them as production dates would propagate the error.		The catalogue estimates do not reconcile.

	The other complication is that the Rolex R.20 case manual does not list the reference. That sounds significant and is not. A contributor on the NAWCC board who checked it reported that the manual's references "end on ref:1831 - and then jump right to ref:5500 nothing in between." The omission spans the entire band from 1832 to 5499, so it says nothing about the 2784 in particular~~. The absence is easy to over-read~~.

	What can be dated is one specific watch: a Solar Aqua 2784 carries a caseback inscription recording its presentation in 1943 by the jewellery department of Eaton's, the Canadian department store. That is the firmest date attached to any example.

	Most 2784s were sold in Canada and the Commonwealth, alongside Oyster-cased watches carrying names like Royalite, Victory, Firefly, Raleigh, Commander, Recorda, Edison, Grenfell, Shipmate, Skyrocket and Standard. Why they exist at all is ~~genuinely~~ disputed ~~among sources that deserve to be taken seriously~~.		Most 2784s were sold in Canada and the Commonwealth, alongside Oyster-cased watches carrying names like Royalite, Victory, Firefly, Raleigh, Commander, Recorda, Edison, Grenfell, Shipmate, Skyrocket and Standard. Why they exist at all is disputed, and the two best-documented accounts contradict each other.

	The widely repeated explanation is a territorial one. Wilsdorf and the Gruen brothers were both shareholders in Aegler, and the agreement between them divided the world: Gruen sold Aegler-powered watches in the United States, Rolex everywhere else. On this account the Canadian Oysters carry Fontainemelon movements because Aegler movements were unavailable to Rolex in North America.		The widely repeated explanation is a territorial one.
