Rolex 2574 Oyster Perpetual
Oyster → 2574
The 2574 is a pre-war manual-wind Oyster produced from at least 1936 through the early 1940s in a 29–30 mm case. This is a "boy's size" watch in the period vocabulary. Two details set it apart from the broader pre-war Oyster population: a 9¾-ligne movement running 17 or 18 jewels depending on the example, and the reference number engraved on the outside of the caseback. The dial is signed "Rolex Oyster Royal," "Rolex Oyster Royalite," "Rolex Oyster Observatory," or "Rolex Oyster Imperial," all drawn from Rolex's late-1930s sub-brand vocabulary, and surfaced examples carry both center-seconds (sweep) and sub-seconds dial layouts. Documented cases run in both stainless steel and 9ct/9K gold, and at least one example carries the retail signature of P. Orr & Sons, the Madras and Rangoon jeweler that sold Rolex across colonial India and Burma.

Where it sits in the line
The 2574 belongs to the small pre-war Oyster group that sits between the earliest 1920s and 1930s Oysters and the wartime platform watches. Its closest sibling is the 2595. Both show what Rolex treated as the smaller end of the men's catalog in the late 1930s. Period material does use the "boy's size" language, but that still meant a legitimate men's watch in its own time.
Rolex sold the 2574 through its usual network of overseas retailers as well as directly. Sotheby's has catalogued an example signed by P. Orr & Sons of Madras and Rangoon, a jeweler that retailed Rolex across colonial India and Burma. This lot documents one overseas retail channel.
By the time 2574 production ended, the Oyster catalog had moved on. The rotor-driven Oyster Perpetual, launched in 1931 on the Bubbleback references, had become Rolex’s main self-winding platform, while wartime platform references carried more of the production. Manual-wind Oysters continued into the late 1940s and early 1950s (the Speedking 4220 runs from 1941 through the early 1950s), but the pre-war Royal/Observatory configuration did not survive the war intact. The surviving records place the 2574 within a short-lived pre-war manual-wind Oyster category.
What distinguishes it
Two details set the 2574 apart. First, some examples carry the reference engraving on the outside of the caseback instead of inside, which is unusual enough to help with authentication. Second, the watch uses a smaller 9¾-ligne Aegler movement running 17 or 18 jewels depending on the example — the Christie's gold example's movement is signed "Rolex Ultra Prima," the top grade in Rolex's mid-1930s Prima naming family — and that caliber appears on the 2574 in two distinct dial layouts.
The 2574 exists in two dial layouts. A center-seconds dial (also called sweep seconds, centre-seconds, or seconde au centre) carries a single long seconds hand pivoting from the center of the dial, alongside the hour and minute hands. A sub-seconds dial (also called small seconds, petite seconde, or sub-dial seconds) carries a separate small register, usually at six o'clock, with its own short seconds hand running on its own pinion. The two layouts require different gear-train configurations downstream of the fourth wheel and are not interchangeable on a finished movement.
On the 2574 both configurations appear among documented examples. The 1943 Royalite Observatory shown above is a center-seconds layout; the 1936 Imperial Chronometer is a sub-seconds layout. Whether early production ran sub-seconds and later production switched to center-seconds, or whether both were offered concurrently, the surfaced sample is too thin to settle. What the dial layout does establish is a quick authentication check: a 9¾-ligne caliber paired with the wrong dial layout for that movement variant points either to a service replacement or to a misidentified reference.
Neither feature is unique to the 2574 in absolute terms. External case engravings appear on other obscure references, and the 9¾ caliber shows up elsewhere in Rolex's late-1930s small-case catalog. Their combination in a 29.5 mm boy's-size steel Oyster is what makes the 2574 specific.
The Royal / Observatory dial question
Two dial signatures are documented on the 2574, both period-correct and both Rolex-applied rather than retailer double-signatures. "Royal" is the more common of the two, part of a late-1930s Rolex dial vocabulary (alongside "Viceroy," "Imperial," and similar names) that ran across the 2280 (1939–1946), 2595 (1938–1941), 3116 (1940–1944), and others. On a 2574, "Royal" is the baseline.
'Observatory' on the 2574 is period marketing language. The watch carries identical hardware whether the dial reads Royal or Observatory; no certification stands behind the word "Observatory."
Case and construction
The 2574 is a three-piece Oyster with a case of about 29.5mm, at the small end of the period men's range.
Lugs are soldered to the case rather than integral-cast or spring-bar-drilled. This is the default late-1930s Oyster construction and is consistent across the 2574 population in the surfaced record. The lugs on a 2574 are narrower than on a 32–34 mm men's Oyster of the same period, proportional to the smaller case. Period strap fit is 14–15 mm at the lugs.
The bezel is smooth and polished, matching the case finish. No engine-turned or decorative bezel variants are documented on the 2574. The decorated-bezel treatments Rolex used on the 3359 Viceroy and similar late-1930s references are not part of the 2574 catalog.
Case material runs in both stainless steel and gold. Christie's catalogued a 9K gold example (Hong Kong, 2003) signed "Rolex Oyster Imperial Chronometre" with import hallmarks for Glasgow 1936, and Gardiner Houlgate catalogued a separate 9ct gold example in 2023. Steel examples are documented at Sotheby's (case no. 126'820, retailed by P. Orr & Sons) and Clevedon Salerooms (case no. 116765). The reference was not a steel-only production; a buyer chose steel or gold the way they would on most of Rolex's late-1930s Oyster catalog. Any gold-cased watch offered as a 2574 on the modern dealer market still warrants verification against the movement specification and the caseback engraving, the same as any other pre-war Rolex.
The movement
The 2574 uses a small pre-Perpetual Aegler movement with Superbalance finishing, running 17 or 18 jewels depending on the specific example, in two variants distinguished by their seconds-train configuration. The center-seconds variant carries an extended fourth-wheel pinion and an indirect-drive sweep seconds hand on the centre. The sub-seconds variant uses the standard fourth-wheel-at-six configuration and reads through a small register at six o'clock. Both run at 18,000 vph, both carry the same Superbalance with self-compensating Breguet overcoil hairspring, and both are rhodium-plated.
The period naming is messy. Rolex catalog and service material from the 1930s and 1940s does not use a single consistent term for either layout, and dealer descriptions still alternate between "centre seconds," "sweep seconds," and "centre-seconds" for the first layout and "small seconds," "sub-seconds," and "petite seconde" for the second. The synonyms refer to the same two architectures.
The 2574 predates later Incabloc and KIF shock-protection systems. Its Superbalance addresses rate stability rather than shock protection. The watch should be handled as a pre-shock-protection movement.
Dial and hand variants
Documented dial signatures on the 2574 include "Royal," "Royalite," "Observatory," and "Imperial," paired with both center-seconds and sub-seconds layouts on a silvered base. The center-seconds dials carry a single long seconds hand from the dial centre. The sub-seconds dials carry a small register at six o'clock with its own short seconds hand. The Imperial Chronometer dial-detail shown above is the sub-seconds layout; the Royalite Observatory hero is the center-seconds layout.
A documented configuration is a silvered dial with applied baton hour markers, “Rolex Oyster Royal” text and sweep seconds. It is consistent with the late-1930s dress-Oyster format. A less common variant substitutes printed Arabic numerals, on both Royal and Observatory dials, still with sweep seconds. Luminous radium dials with Arabic numerals and matching luminous hands appear on Royal-signed examples; radium-filled configurations on the 2574 tend to show heavy age-darkening, and cleanly white radium plots on a 2574 are a sign of restoration.
Documented hand configurations include leaf, baton and, on radium-dial examples, luminous-filled pencil or spade hands. Blued steel leaf hands appear on the cited original-dial Royal examples. Matched patina between dial printing, lume, and hands supports a period-original set; mismatched aging is one sign of a possible service replacement.
Auction and dealer record
The cited auction record is small but includes a Sotheby’s lot and a Christie’s lot. Sotheby's sold a steel example retailed by P. Orr & Sons of Madras and Rangoon at its 2023 Fine Watches sale (estimate USD 3,000–5,000, cream dial, 17-jewel caliber, no box or papers). Christie's sold a 9K gold example at its Hong Kong Important Watches sale in 2003 for HKD 20,315 against a HKD 7,000–10,000 estimate — the movement signed "Rolex Ultra Prima," 18 jewels, with Glasgow import hallmarks dating the piece to 1936. Two smaller UK salerooms round out the record: Gardiner Houlgate sold a 9ct gold example for GBP 750 in 2023, and Clevedon Salerooms sold a steel example for GBP 550 in 2025, the latter fitted with a later replacement bracelet.
The cited record includes Royal-signed steel examples with baton or Arabic dials; Observatory-signed examples are fewer in the sources reviewed. The cited results span GBP 550 to a USD 5,000 estimate. They cover different materials, conditions and venues, and do not establish a current price range.
Collecting considerations
The outer-caseback reference engraving is one useful authentication check. It should be legible without looking newly cut; decades of wear can soften it, while unworn examples may retain crisper text. Extremely sharp or machine-perfect engraving is a warning sign, either a recent re-engraving on a worn caseback or a replacement caseback with modern work. Extremely soft or shallow engraving is compatible with heavy wear but should be cross-checked against the interior caseback for consistent period signatures.
The movement specification is the clearest cross-check when the engraving is ambiguous. A 2574 should carry a 9¾-ligne Aegler movement with Superbalance and Breguet overcoil, running 17 or 18 jewels, in either the center-seconds or sub-seconds variant. A 10½′′′ caliber, a 15-jewel specification, or a dial layout that does not match the gear-train configuration of the movement variant present points either to a service replacement (possible on any 80-year-old watch) or to a misidentified reference. Because both layouts exist on documented 2574 examples, the dial layout alone cannot disqualify a candidate; the layout has to match what the movement underneath was built to drive.
The cited sources do not establish how many surviving 2574 dials were refinished. Originality should be assessed from printing, lume or radium ageing, hand matching and movement fitment, ideally with specialist comparison.
The auction table records GBP 550 and GBP 750 at the two UK salerooms, a USD 3,000–5,000 estimate at Sotheby’s and HKD 20,315 at Christie’s. These are individual results, not a valuation guide.
A 29.5 mm case is small by modern wrist-sizing conventions. The period “boy’s size” label describes the catalogue category; the case dimensions and strap fit are the practical points for an individual watch.
