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." The Battle of Britain framing is universally repeated and never primary-sourced.

The 4925 sits at the front of every Air-King story. The Air-King line has no pre-1945 history; the 4925 is where the dial-text designation begins. It runs alongside the 4365 (1945, sub-seconds variant on the same case architecture, the canonical Air-Lion / Air-Tiger / Air-Giant case), the 4444 (mid-size with solid-gold bezel and crown, ran Air-Lion / Air-Giant / Air-King dial-signed examples), the 4647 (Hunter Precision case that surfaces with Air-Lion signing), and the 4499 (1946 onward, an upgraded 17-jewel running mate that some sources read as the 4925's successor and others as a parallel sibling). Reading 4499 as a strict successor is the ''Time-Wire'' line; Goldammer, Beckertime, and ''Rolex Magazine'' read the four-reference launch as parallel.

The case architecture handed off to the 6552 in 1953 — same 34mm Oyster envelope, but with the new automatic Cal. 1030 underneath and an applied coronet at twelve replacing the early printed-coronet dial layout. The 5500 (1957–89) succeeds the 6552 and runs the Cal. 1530 / 1520 generation across the Air-King line for 32 more years. Time-Wire's reading that 5500 is the direct successor to 4925 skips the 6552 entirely and is incorrect; the canonical sequence is 4925 → 6552 → 5500.

The launch year is firm. 1945 across Goldammer, Monochrome (Erik Slaven, January 2025), Rescapement (Tony Traina), Beckertime, ''Rolex Magazine'' (Jake Ehrlich, 2013), Robb Report, and Watch-Wiki. The 1945 launch ties the Air-King naming directly to the end of the war and the Battle of Britain commemoration the canon attaches to it.

The end year is contested. 1953 is the consensus retirement date — Goldammer, Monochrome, Rescapement, Beckertime, Robb Report. Antiquorum lot 382 (25 September 2002) reads instead "the Air-King was first introduced in 1953 in honor of the Royal Air Force pilots who flew in the battle of Britain," treating the automatic 6552 as the "real" launch — a major-house catalogue text that contradicts the 1945-launch consensus. ''Time-Wire'' narrows the 4925 specifically to "approximately 1945–1946" and reads the 4499 as its 1946 replacement. Sotheby's lot 190 (4 September 2020) catalogues a 4925 by case number 354,085 to c.1956, and a Beckertime / eBay artifact carries a 1958 dial — both push the upper bound past the 1953 consensus.

The cleanest reading: 4925 enters the catalogue in 1945, is formally retired in 1953 when the automatic 6552 takes over, and continues to be cased and dispatched out of leftover stock into the late 1950s. 1945–1953 is the active production window; case-number examples post-1953 are late stock.

The framing canonical to every published Air-King history: Hans Wilsdorf was in London during the Battle of Britain and watched RAF pilots privately purchase Rolex Oysters because they preferred them to military issue, and the 1945 Air-King naming commemorated those pilots. Monochrome, Goldammer, Rescapement, ''Rolex Magazine'', Robb Report, ''Revolution'', Foundwell, Analog:Shift, and Craft + Tailored all carry the framing in close-to-identical form.

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." The framing is universally repeated and never primary-sourced.

The Air-King launches alongside three sister names in the 1945 commemoration. None of the three runs on a dedicated reference number; instead the names share refs 4365 (sub-seconds 10½ Hunter), 4444 (mid-size with solid-gold bezel and crown, 31.75mm), and 4647 (Hunter Precision case). Goldammer publishes a side-by-side photograph captioned "Air-Tiger (left), Air-Giant (middle) and Air-Lion (right) — all reference 4365 from the 1940s," confirming the same case-and-movement combination took whichever sister name the market called for.

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.
