Reference:3139
Oyster → 3139
The 3139 is the only Rolex ever produced with “Army” on the dial. That single word, printed beneath the twelve-o’clock coronet on a stainless steel cushion-cased wartime Oyster, is what the reference is collected for. Production ran from roughly 1938 to 1947, spanning the Second World War and its immediate aftermath. Roughly three thousand pieces are said to have been supplied to Allied troops during the war years, though the reference carries no formal military issue markings of any kind: no W.W.W., no broad arrow, no service numbers from the factory. “Army” is Rolex’s commercial wartime designation. The 3139 is the watch Rolex sold for the war, not a watch any government issued.

Where it sits in the line
The 3139 occupies a particular niche in Rolex’s late-1930s and wartime Oyster catalog. By 1938, the Oyster range had fractured into two clear tracks: the round, rotor-driven Perpetual Bubblebacks that were becoming the company’s technical flagship, and the manual-wind Oysters in varied case forms (round, tonneau, cushion, octagonal) that Rolex continued to sell through European, British, and Commonwealth channels. The Perpetual was the future; the manual Oysters were the present business, and they were selling very well.
The 3139 is a manual-wind cushion Oyster in that second track, aimed straight at wartime customers. It sits alongside the tonneau-cased 3116 “Royal/Viceroy/Imperial” family, the smaller-case Canadian-market Oysters (3136 “Raleigh/Lipton,” 3478 “Recorda,” and their siblings), the 4220 Speedking, and the 3359 Viceroy, a cohort of WWII-era Rolex manual-winds that servicemen bought in large numbers for themselves. Among these, the 3139 is the only one that carries the word “Army” on the dial. That distinction is the reference’s entire identity.
The case form is older than the war. The cushion Oyster descends from the 1926 Oyster catalog’s original cushion shape, one of the two shapes (octagonal and cushion) that Rolex launched the Oyster with. Both, in turn, descend structurally from the three-piece hermetic screw-case patented by François Borgel in 1903, which Rolex’s earliest Oysters used in Borgel-made form before the company refined the construction around its own screw-down crown. By the time the 3139 arrived, the cushion form had been out of Rolex’s mainstream line for over a decade. Its revival for a wartime military-branded watch is part of the reference’s appeal: a deliberately old-fashioned case for a watch sold to soldiers.
There is one relationship worth naming directly. Rolex manufactured cases for Panerai in this same period, and the Panerai reference 3646 is a cushion-cased Rolex-made watch of the wartime years. The two are cousins within the Borgel-derived Oyster cushion family, but they are not twins. The 3646 is a 47 mm pocket-watch-derived diver’s case with wire lugs, produced for the Italian Royal Navy; the 3139 is a 30–35 mm wristwatch case with heavy soldered faceted lugs, produced for the Anglo-American market. Common ancestry, separate construction. The family resemblance is real; the watches are not interchangeable.
The “Army” question
The dial text is unambiguous. Below the coronet and “ROLEX OYSTER,” the word “ARMY” appears in block capitals, with “SWISS MADE” at the six-o’clock minute track. No other Rolex dial carries that word. The reference is routinely described in dealer copy and collector forums as a “military-issued” watch supplied to Allied troops, and the approximately three-thousand-unit production figure is cited as the wartime distribution total.
The markings tell a different story. None of the surfaced 3139 examples (Antiquorum 2006, Antiquorum 2014, Bonhams, Bulang & Sons, Lunar Oyster, Connoisseur of Time, WannaBuyAWatch) carry formal military issue marks. There is no W.W.W. (Watch, Wrist, Waterproof — the British Ministry of Defence standard applied to the “Dirty Dozen” issue watches of 1945). There is no broad arrow. There is no Allied service number engraved on the caseback from the factory. Service-number engravings do appear on some examples, but they are owner engravings, added post-purchase in the field, not factory-applied issue marks.
The correct frame is commercial. Rolex sold the 3139 during the war years, branded it for the military customer, and distributed it through the same channels (retailers, PX stores, direct sales) that served officers and servicemen buying their own watches. The three-thousand-unit figure reflects that commercial distribution, not a government contract. When Rolex did win a military contract, as it did for the W.W.W. reference 6B/346, the watches carried the issue marks; the 3139 does not, and the absence is evidence that this was a different transaction.
The word “Army” on the dial is real. The marketing of the watch as a wartime military Oyster is real. The suggestion of a government issue contract is not. The 3139 was a commercial watch with a military-themed dial, sold to soldiers and others who wanted to carry one. That reading accounts for the dial text, the production span, the distribution figure, and the absence of issue marks without contradiction.
Case and construction
The 3139 case is a cushion (a squared form with curved edges, not a circle) in stainless steel. Thickness is approximately 11.5 mm, putting it firmly in the substantial-wartime-tool category rather than the slimmer 1930s dress-Oyster register. The lugs are the signature visual element: heavy, faceted, soldered to the case rather than milled integrally, meeting the case at sharp angles and stepping back to the strap attachment with distinct bevels. The lug construction is what separates the 3139 visually from the smaller cushion Oysters of the 1920s–30s that used thin wire lugs. These are substantial lugs for a substantial watch.
The case carries the reference 3139 engraved between the lugs on the underside, and the standard Oyster caseback text on the interior. The back is a screw-down three-piece element consistent with Oyster architecture. The crown is a screw-down Oyster Patent crown, threaded to the case tube.
Two case sizes are documented under the same reference. The more frequently surfaced size is the mid-sized configuration of approximately 30×30 mm, a squared cushion read on the wrist as a 30 mm watch, with Antiquorum’s 2006 and 2014 lots both falling in this range. A larger 30×35 mm variant also appears, carried by WannaBuyAWatch among others, with the extra five millimeters going into the vertical axis to give the case a slightly rectangular cushion proportion. Whether the two sizes represent different production runs, different export markets, or overlap within the same production window is not documented in the surfaced record. Both are legitimate 3139 cases; a prospective buyer should measure what they are looking at rather than assume a single size.
Known case numbers anchor the reference to specific production years. Case 244828 is dated 1942 by Antiquorum. Case 244874 is dated approximately 1943. Case 245141 is dated approximately 1945. Case 275869 appears without a firm date. Case 382045 was catalogued by Antiquorum as “1930s,” which is implausible given the reference’s 1938 production start. The case number falls in a serial range consistent with the mid-1940s, and the catalog dating is most likely a typographic or indexing error. The correct reading is that 382045 is a wartime or late-war piece, not a 1930s piece.
The movement question
Surfaced listings attribute the 3139’s movement in two ways. Some sources describe the calibre as the 10½-ligne Hunter, a 17-jewel manual-wind movement with straight-line lever escapement, Rolex-patented Superbalance, Breguet overcoil hairspring, centre sweep seconds, and adjustment in six positions for all climates. Others describe the calibre as the Rolex 710, a 17-jewel manual with 18,000 bph, 44-hour power reserve, and two-position adjustment.
The specifications overlap enough that the two attributions most likely describe the same physical movement under different naming conventions. The “10½ Hunter” designation reflects the movement’s architectural family (the 10½-ligne Hunter-calibre base Rolex used across its 1930s and 1940s manual Oysters), and the “710” designation reflects a later Rolex internal calibre number applied to the same base. Where the descriptions differ (six-position versus two-position adjustment) the difference probably reflects different production grades across the run, with earlier or higher-grade 3139s adjusted to six positions and later or standard-grade examples adjusted to two. Period Rolex movement documentation for this specific reference is thin, and a definitive reconciliation would require factory records that have not surfaced.
What the movement delivers on the wrist is consistent. Manual-wind operation via the screw-down Oyster crown, seventeen jewels, a centre sweep seconds hand on most configurations, and approximately forty hours of power reserve. The Superbalance and Breguet overcoil specifications, where present, are consistent with the precision-grade manual Rolex produced across its better late-1930s Oysters. No shock protection of the modern Incabloc or KIF type is present. Shock-protected Rolex calibres arrive later in the 1940s with the A.296, and the 10½ Hunter base predates that development.
Dial variants
The 3139’s dial range is where the reference acquires most of its collector interest. Five configurations are documented across auction and dealer sources, and the dial variant is by far the most significant driver of market value among surviving examples.
The California dial is the two-tone configuration: Roman numerals on the upper half, Arabic numerals on the lower half, radium luminous plots at the tips, and a railroad-style minute track. The California is the top-tier 3139 dial. Rolex’s period name for the layout was “Error-Proof” or “High Visibility”; the “California” name came from 1970s–80s refinishers and stuck. A 3139 with a documented-original California dial commands a substantial premium over other variants and is the configuration most frequently featured in auction-house material.
The black glossy gilt variant uses a black enamel or lacquer base with gilt (gold-coloured) printing for the dial text, hour markers, and minute track. The glossy gilt 3139 is the variant most prized by gilt-dial collectors, with the ROLEX OYSTER ARMY text reading in gold against a deep black field. Lunar Oyster has offered unpolished examples with original glossy gilt dials at strong prices. This dial configuration is highly sought after and, in original unrestored condition, is the variant most likely to attract serious dial-variant-focused buyers.
A silvered dial with baton indices is the more conservative treatment: silvered base, applied or printed baton hour markers, a simple minute track, and blued steel hands. This is the 3139 in its dressiest, least overtly military configuration, and it is the variant most likely to carry the reference through a non-military retail channel. Period-appropriate and attractive, but collected at lower prices than the gilt and California dials.
A matte black dial with green Arabic numerals is the tool-watch configuration: matte black base, Arabic hour numerals in luminous or green-painted radium, with a corresponding luminous handset. Reads very directly as a wartime military-themed dial. Documentation for this variant is less extensive than for the California and gilt configurations, but it surfaces in period examples and is consistent with the 3139’s wartime-customer positioning.
The military-layout luminous dial carries Arabic or baton markers, full luminous plots, and sometimes a 24-hour inner track, the closest the 3139 gets to a formal military-issue dial, though as noted above, it carries no formal issue markings. This configuration is the one most frequently described in dealer copy as “military” and is the dial most likely to be paired with Mercedes luminous hands.
Hands come in two principal configurations. Mercedes hands with luminous fill (the three-spoke hour hand that became the Rolex tool-watch signature from the Submariner onward) appear on the military-layout and matte-black 3139s. Blued pencil hands with radium appear on the silvered and some gilt configurations. Matching patina between dial and hands is the standard authenticity check; mismatched aging indicates a service replacement somewhere along the chain.
The Panerai 3646 relationship
Rolex manufactured Panerai’s cases during the Second World War. The Panerai reference 3646, produced from 1938 through the mid-1940s as a diver’s watch for the Italian Royal Navy’s underwater assault units (the Decima Flottiglia MAS), is a Rolex-made cushion case in a 47 mm pocket-watch-derived format, fitted with wire lugs and a California dial. It carries a Cortébert movement rather than a Rolex calibre, because Panerai specified the ebauche.
The 3139 and the 3646 are related by case family. Both descend from the Borgel-derived cushion Oyster architecture that Rolex developed in the 1920s and refined through the 1930s. The resemblance is most apparent in the cushion geometry (curved-edge square form, not round) and in the three-piece hermetic screw-case construction. On a photograph of the bare cases, the family relationship is immediate.
The differences are also immediate. The 3646 is dramatically larger, aimed at wrist-over-wetsuit visibility and driven by the Italian Navy’s functional brief; the 3139 is a standard-wrist wristwatch at 30–35 mm. The 3646 uses thin wire lugs that accept leather or rubber straps appropriate to diving; the 3139 uses heavy soldered faceted lugs. The 3646 carries a Cortébert movement with a locked-crown system for waterproofing; the 3139 carries a Rolex Hunter or 710 calibre with a standard Oyster screw-down crown. The dial configurations overlap (both can wear a California dial) but the dial texts are unrelated.
The correct frame is cousins, not twins. The 3646 and the 3139 are both Rolex-made wartime cushion-cased watches from the same case family, produced on overlapping timelines, with different intended customers and different technical configurations. Collectors who work across both references describe them as a single design language expressed at two scales for two markets. The frequent conflation in casual dealer copy, which treats the two as near-identical, overstates the technical kinship.
Auction and dealer record
The 3139 is a mid-tier vintage Rolex by value but a specialist collector’s watch by character. Its auction record is steadier at smaller houses and specialist dealers than at the major international rooms, and the variance between dial variants is substantial.
Antiquorum Geneva catalogued a 3139 in 2006 within its wartime Rolex lots, and a second 3139 appeared in 2014 Antiquorum programming. A specific Antiquorum lot ties to case number 244828, dated 1942, a representative mid-sized 3139 example.
Antiquorum also catalogued the case number 382045 example as “1930s,” a dating inconsistent with the reference’s 1938 production start and with the serial range of the case number itself. The catalog entry is read by collectors as a dating error; the watch is a wartime or late-war 3139.
Bonhams has offered 3139 examples across its auction programme, consistent with the reference’s stable specialist market presence.
Bulang & Sons has listed the 3139 on its dealer site, describing the reference as a manual-wind wartime Oyster Army.
Lunar Oyster has offered multiple 3139 examples, including 1942 and 1943 unpolished cases with original black glossy gilt dials, the variant that drives the strongest dealer pricing for the reference.
WannaBuyAWatch has offered a larger-case (approximately 30×35 mm) 3139, the size variant that falls outside the more common 30×30 mm configuration.
Connoisseur of Time has catalogued the 3139 within its WWII-era Rolex inventory alongside references like the 2849 Lifesaver and the 3116 Imperial Chronometer.
The working market range for the 3139 in typical condition with a standard dial (silvered baton, matte black, or military-layout luminous) falls in the USD 3,000–5,000 range. Black glossy gilt examples in unpolished condition reach the USD 5,000–7,000 band, with exceptional pieces trading above. California dial examples, when documented as original, are the pricing outliers and can exceed the top of that range substantially. Restored dials sit below the standard market for each variant, and pieces with clear owner-engraved service numbers (authentic wartime provenance, not factory issue marks) often carry a small premium with collectors who value the personal-history dimension.
Collecting considerations
Dial originality drives the 3139’s value more than almost any early Oyster reference. An original dial, even with honest wear, reads meaningfully different from a refinished example, and the gap in collector interest is substantial. Gilt printing on the glossy black variant is particularly difficult to replicate convincingly at refinish quality; California dials, likewise, carry telltale signs (printing register, luminous plot shape, radium patina) that specialists use to distinguish originals from high-grade redials. Where dial originality is uncertain, the conservative position is to price the watch as refinished and treat any original-dial upside as a bonus.
Case size matters practically on the 3139. Buyers expecting a mid-sized 30×30 mm watch who encounter a 30×35 mm example (or vice versa) will find the wrist presence meaningfully different. Measure the case across both axes before assuming which size is in the box.
On case numbers and dating, the surfaced serials cluster in the 244,000–245,000 range for wartime examples (244828, 244874, 245141) and extend into higher ranges (275869, 382045) for later production. Dating via case number is reasonably firm within this cluster. Antiquorum’s “1930s” attribution on 382045 is the one anomaly in the surfaced record; the consensus reading places that case in the mid-1940s.
Caseback engravings (service numbers, names, dates) are almost always owner additions. Engravings on the caseback exterior are owner additions, not factory issue marks. A serviceman’s name, service number, unit, or date of issue engraved on the back is provenance information, not authentication of government issue. Where such an engraving ties to a documented serviceman, it is an attractive provenance layer; where it is present but undocumented, it is neutral. The absence of a broad arrow or W.W.W. is not a defect of the watch; no 3139 left the factory with those marks.
The movement should be signed with the Rolex wordmark and carry seventeen jewels, the 10½ Hunter or 710 architecture, and manual-wind operation via the Oyster crown. A replacement movement of a different architecture (automatic, larger calibre number, or different jewel count) indicates a service substitution somewhere in the watch’s history.
Polish condition is the last check, and it matters. The faceted lugs are the 3139’s defining visual feature, and they do not survive aggressive polishing. An unpolished 3139 with sharp lug facets reads very differently from a polished example where the facets have rounded into continuous curves. Unpolished examples command a premium and, on the glossy gilt and California dial variants, are the pieces most likely to attract the top of the market.
Still open
Several questions about the 3139 are not fully resolved in the surfaced public record.
The exact production total
The figure of approximately three thousand units supplied to Allied troops during the war years appears repeatedly in dealer and collector literature but is not tied to a Rolex factory document in any surfaced source. It is a plausible figure given the case-number range and the reference’s surfaced population, but it carries the provenance of a repeated collector claim rather than a factory-confirmed total.
The two case sizes
Whether the 30×30 mm and 30×35 mm configurations represent parallel production, sequential production, market-specific variants, or an error in one set of sources’ measurement conventions is not documented. Both sizes are well-attested; their relationship within the reference is not.
The movement naming
Whether the Cal. 10½ Hunter and Cal. 710 attributions refer to the same physical movement under different names, to two different movements produced across the run, or to one movement with two specification grades (six-position versus two-position adjustment) remains an unresolved question. Period Rolex calibre documentation for the 1938–1947 manual-wind Oysters is not publicly comprehensive, and a definitive reconciliation has not surfaced.
The commercial distribution channels
The 3139 clearly reached servicemen during the war. Whether that distribution ran primarily through military PX stores, through British and European retailers, through Swiss direct sales, or through some combination is not documented in the surfaced record. The parallel Canadian-market Oysters of the same period used documented retailer channels (Birks, Eaton’s); the 3139 does not appear in those retailer records in the same way, consistent with its positioning as a more broadly targeted military-themed commercial product rather than a retailer-specific private label.
The case number 382045 dating
Antiquorum’s “1930s” dating for the 382045 example is inconsistent with the reference’s 1938 start and with the serial range of the case number. The most parsimonious reading treats the dating as a catalog error and places the case in the mid-1940s. Without access to the original Antiquorum documentation to check whether the “1930s” figure is a typographic artifact or a deliberate attribution, the question is practically resolved but not documentarily closed.
