Reference:4925: Difference between revisions

The 4925 is the first Rolex Air-King — the 1945 hand-wound 34mm Oyster that gave the line its name. It launches alongside three sibling names: Air-Lion, Air-Tiger, Air-Giant. By the early 1950s only the Air-King survives. The 4925 carries the Air-King designation forward through the late 1940s and into the early 1950s, then hands off to the automatic 6552 (1953–57) and ultimately to the long-running 5500 (1957–89). Without the 4925 there is no Air-King line at all.

Inside the four-name commemoration sits a story that everyone repeats and nobody can primary-source. Hans Wilsdorf had been in London during the Battle of Britain and watched RAF pilots privately purchase Rolex Oysters because they preferred them to military-issue alternatives; the 1945 Air-King naming was, the canon goes, his commemoration of those pilots. Monochrome (Erik Slaven, January 2025), Goldammer (Marcus Siems), Rescapement (Tony Traina), ''Rolex Magazine'' (Jake Ehrlich, 2013), Robb Report, and ''Revolution'' all carry the framing in roughly identical form. None cite Wilsdorf's words, a period Rolex marketing piece, or Dowling and Hess's ''The Best of Time'' (the obvious candidate book). Craft + Tailored is the only publisher that prefaces the story with "according to legend." Treat the Battle of Britain framing as universally repeated and primary-source unverified.

Total production output is not published by Rolex for any 4925. The reference is scarce at major-house auction — Sotheby's lot 190 (2020) is the only standalone Phillips / Sotheby's / Christie's / Bonhams 4925 lot to surface in the auction record. Antiquorum has stronger 4925 coverage but most Antiquorum Air-King lots from the 1990s and 2000s are 5500-era rather than 4925. The two Baer & Bosch lots (AN3907 and lot 3189, both 2019) round out the documented record.

The canonical 4925 dial. Eggshell or cream ground, applied gold Arabic hour markers in a shallow avant-garde font, leaf or pencil hands, blued central seconds. Rolex crown printed below twelve, "OYSTER AIR-KING" beneath, simple track of matching applied dots around the perimeter. Monochrome describes this as the originating layout; the Baer & Bosch 2019 lot AN3907 confirms the configuration ("silver Rolex Oyster Air-King dial with applied gold-tone Arabic and arrowhead hour markers"). The dominant configuration on early-to-mid production 4925s.

The Roman, sector, salmon, honeycomb, clous-de-Paris, tropical, RAF crest, and retailer-signed (Asprey, Tiffany, Beyer, Cartier, Gübelin) 4925 configurations are not documented in major-house lots. A 1958-dated eBay listing surfaces a "Military Dial" 4925 — treat as an unverified lead rather than a documented variant.

The case is steel-only across documented examples. The 4444 (Air-Lion / Air-Giant / Air-King) carries a documented two-tone construction with a solid-gold bezel and crown, but the 4925 is consistently catalogued in plain steel. Sotheby's lot 190 (2020) gives 33mm rather than 34mm — within measurement-method tolerance for a watch usually quoted at 34mm. Across all surfaced major-house lots the case dimensions read consistent.

No primary source surfaces in this article's research pass. None of the published editorial cites Wilsdorf's words, period Rolex marketing material, or Dowling and Hess's ''The Best of Time'' (the canonical Rolex history book and the obvious candidate for the primary source). Craft + Tailored is the only publication that prefaces the story with "according to legend." Treat the framing as universally repeated and primary-source unverified.

The 4444 is the most-documented mid-size sister: A documented 4444 Air-Lion (steel with solid-gold bezel and crown, 17-jewel manual) is described in dealer catalogue text as "extremely uncommon, having encountered only one other in over 35 years." The 4647 surfaces less frequently — Foundwell catalogues a 4647 Air-Lion (~1947, 31×39mm Hunter Precision), the only 4647 surfaced in the auction record.

The 4925 is scarce at major-house auction. Phillips, Christie's, and Bonhams have no documented standalone 4925 lots through 2025. Sotheby's lot 190 (2020) is the only Phillips-tier 4925 to surface in the auction record and did not sell at its USD 5,000–7,000 estimate. The visible auction record sits well below 10 strong examples — a function of the 1945 production window's age, the modest profile of the watch in its day (this was an entry-level Rolex, not a flagship), and the 80-year service-and-restoration history that has compromised most surviving examples.

The 4925 is 80 years old. Most surviving examples have been serviced multiple times across that span, and dial restoration was particularly common during the 1980s–2000s collector window when the early Air-King was less prized than it became after the Air-King family's rediscovery. Eric Wind, writing at Wind Vintage, on dial restoration across the early Rolex line applies here: a perfectly clean original dial on an 80-year-old 4925 should be treated as suspect; period patina (silvering loss, applied-marker shadowing, lume aging on the printed coronet) is the originality positive.

The case interior should carry the 4925 reference stamp and a Roman-quarter date code consistent with the 1945–1953 production window. Case numbers in the auction record run roughly 350,000–360,000 (Sotheby's lot 190 case 354,085) for the late-production examples; earlier 4925s carry lower case numbers. A 4925 with a case number outside this band — particularly any case number above 400,000 — should be examined carefully; case-stock assembly into the late 1950s is documented but not unlimited, and a much later case number is more likely a service-replacement case middle than original delivery.
