The 4365 is the sub-seconds sister to the centre-seconds [[Reference:4925|4925]] in the 1945 Battle of Britain Air-King launch. The two references run in parallel from 1945 through approximately 1953, sharing the Cal 10½ Hunter movement family but splitting across the dial layout: 4925 is centre-seconds, 4365 is sub-seconds with the small seconds register at six. Where the 4925 carries the Air-King name only, the 4365 carries the full four-name commemoration — Air-King, Air-Lion, Air-Tiger, Air-Giant — printed on the dial of period examples that share a single case and movement. Marcus Siems' published side-by-side photograph captioned ''"Air-Tiger (left), Air-Giant (middle) and Air-Lion (right) — all reference 4365 from the 1940s"'' is the strongest single evidence anchor for the four-name dial-map convention.
The 4365 is the sub-seconds sister to the centre-seconds [[Reference:4925|4925]] in the 1945 Air-King launch. The two references run in parallel from 1945 through approximately 1953, sharing the Cal 10½ Hunter family but using different dial layouts: 4925 is centre-seconds, while 4365 has the small seconds register at six. Period examples carry Air-King, Air-Lion, Air-Tiger or Air-Giant text on the dial. Marcus Siems' published side-by-side photograph documents Air-Tiger, Air-Giant and Air-Lion examples as 4365s.


By the early 1950s Rolex retires Air-Lion, Air-Tiger, and Air-Giant from the catalog. Only Air-King survives. Tudor revives Air-Tiger on its own ref 7957 (documented at Foundwell c.1959 and Analog:Shift c.1964); Air-Lion and Air-Giant make no jump and disappear entirely. The 4365's role in this narrative is the canvas on which the four-name commemoration was tested: Rolex used a single case and movement combination to carry four marketing identities to four notional pilot-watch sub-segments, and the market (or the dealer ordering pattern) selected only one.
By the early 1950s the catalog uses Air-King alone. Tudor later used Air-Tiger on ref. 7957, while Air-Lion and Air-Giant do not appear in the later Tudor records cited here. The four names should be treated as dial variants on the early Air references, not as separate 4365 case references.

The 4365 sits at the dial-layout fork in the 1945 Air-King launch. Rolex commemorated the Battle of Britain naming exercise across three case configurations and four dial names. The case configurations: Bubbleback-class 32-34mm Oyster (4365), Bubbleback-class 34mm Oyster centre-seconds (4925), mid-size 31.75mm with solid-gold bezel and crown (4444), Hunter Precision case (4647). The dial names: Air-King, Air-Lion, Air-Tiger, Air-Giant. The 4365 carries the broadest dial-name distribution because of Siems' documented photographic evidence — the same 4365 case ran with three of the four sister names, plus a small subset of confirmed Air-King-marked dials.
The 4365 sits at the dial-layout fork in the 1945 Air-King launch. The documented case group includes the Bubbleback-class 32–34mm Oyster 4365, the centre-seconds 4925, the mid-size 4444 with solid-gold bezel and crown, and the Hunter Precision 4647. Air-King, Air-Lion, Air-Tiger and Air-Giant text appears across the period Air references; Siems' photographs document three of those names on 4365 examples.


The architectural relationship to the 4925 is the cleanest framing. Both references launched in 1945 with the Cal 10½ Hunter movement family. Both carry steel Bubbleback-class Oyster cases. The 4925 carries centre-seconds with sweep (the visually-newer dial layout that becomes the post-war standard); the 4365 carries the sub-seconds layout with the small register at six (the more traditional pre-war dial language). Rolex offered both layouts in parallel through the late 1940s and into the early 1950s, then retired the sub-seconds 4365 alongside the centre-seconds 4925 by approximately 1953 when the 6552 takes over with the Cal 1030 automatic.
The architectural relationship to the 4925 is direct. Both references launched in 1945 with the Cal 10½ Hunter family and steel Oyster cases. The 4925 carries centre-seconds; the 4365 carries the small register at six. Rolex offered both layouts in parallel through the late 1940s and into the early 1950s, then replaced them around 1953 with the automatic 6552 and Cal 1030.


The case is supplied by the same Aegler-related case-supply chain as the 4925. The Bubbleback-class envelope sits closer to the post-war flat Oyster than to the pre-war Bubbleback proper — the Cal 10½ Hunter doesn't need rotor clearance. Lugs are 19mm with drilled spring-bar holes. The bezel is fixed and steel and smooth. The crown is manual-brevet screw-down.
The case has a flatter profile than a rotor-driven Bubbleback because the Cal. 10½ Hunter movement does not require rotor clearance. Lugs are 19mm with drilled spring-bar holes. The bezel is fixed, steel and smooth. The crown is a manual-wind brevet screw-down.


A documented 4365/6022 composite case appears in late-1950s production. Bonhams 2023 Canadian Collection lot 17 catalogues a 4365/6022 Air-Lion dated c.1958 — the secondary reference 6022 is a service-case from a later run, indicating Rolex serviced and re-cased original 4365 movements into 6022-style cases as late as 1958. Documented 4365/6022 examples are service-era refits rather than original-delivery 1940s production.

The 1945 launch year is consensus across Marcus Siems' Air-King family history, Monochrome (Erik Slaven, January 2025), Rescapement (Tony Traina), Watch-Wiki, Chronoclub, Robb Report, and ''Rolex Magazine'' (Jake Ehrlich). The 4365 ships in the same 1945 Battle of Britain launch alongside the 4925, 4444, 4647, and the broader four-name commemoration set.
Published Air-King histories place the 4365 launch in 1945 alongside the 4925, 4444 and 4647. The four names belong to the dial variants documented in that launch group.


The retirement is consensus 1953, mirroring the 4925's catalog cutoff. The Cal 10½ Hunter movement family retires with the broader pre-1030 hand-wound Air-King line, and the 6552 (1953-1957, first automatic Air-King with Cal 1030) takes the line forward. The 4365/6022 composite-cased examples that surface dated 1958 (Bonhams 2023 lot 17) are service-replacement re-cased examples rather than late-stock continuation production — Rolex assembled or re-cased original 4365 movements into 6022-style cases up to several years after the 4365 itself retired from the catalog.
Published histories place the 4365 and 4925 cutoff around 1953, when the automatic 6552 and Cal 1030 take over. The 4365/6022 example dated 1958 in Bonhams lot 17 is a service-case example, not evidence of continuing original 4365 production.


Total production output is not published. The 4365 is scarce at major-house auction — four documented lots in the auction record through 2025 (Bonhams 2023 Air-King, Bonhams 2023 Air-Lion, Bonhams 2023 Air-Tiger, Antiquorum 2001 18K pink gold Precision). Sotheby's, Phillips, and Christie's have no documented 4365 lots in the auction record. The 1945-era short production window, the 4365's modest profile in its day, and the four-name dial-marketing complexity that obscures the catalog presence keep the auction record thin. The Siems side-by-side photograph carries more weight than any single auction-house lot.
No production total is published. The cited auction record contains four Bonhams and Antiquorum lots through 2025. Variant identification still depends on the dial, case and movement together.

The 4365 runs the Cal 10½ Hunter family in its sub-seconds layout — small seconds register at six rather than the centre-seconds sweep of the 4925. The 700-series base architecture (700 / 710 / 720 / similar) and the 15j → 17j running update mirror the 4925's progression; see [[Reference:4925#movement-notes|the 4925 movement notes]] for the canonical caliber breakdown.

The case profile reads closer to the post-war flat-case Oyster than to the pre-war Bubbleback proper; the Cal 10½ Hunter doesn't need rotor-clearance dome.

The 4365 is not COSC chronometer rated. The dial reads PRECISION across documented examples; "Super Precision" attribution on a 4365 dial is service-replacement (likely a 5500-era Cal 1530 dial swap applied during service) and is not original.

Bonhams 2023 Canadian Collection lot 17 catalogues a 4365 Air-Lion movement in a 6022 service-replacement case dated c.1958. The convention indicates Rolex serviced and re-cased original 4365 movements into 6022-style cases as late as 1958, several years after the 4365 itself retired from the catalog. 4365/6022 composite-cased examples are service-replacement variants rather than original-delivery production. The 6022 secondary reference is a later-period service case, not a continuous-production sub-line.
Bonhams 2023 Canadian Collection lot 17 catalogues a 4365 Air-Lion movement in a 6022 service-replacement case dated c.1958. The lot documents a 4365 movement in a 6022 service case in 1958, several years after the commonly cited 4365 production period. It is a service-case example rather than evidence of continued original 4365 production. The 6022 secondary reference is a later-period service case, not a continuous-production sub-line.


The Tudor Air-Tiger ref 7957 cross-brand continuation (Foundwell c.1959, Analog:Shift c.1964) carries the Air-Tiger name forward on the Tudor side after Rolex retires it. The cross-brand Tudor 7957 is not a 4365 sub-variant but is the genealogical successor to the 4365 Air-Tiger sister-name dial. A documented 4647 Air-Lion (~1947, 31×39mm Hunter Precision) and the 4444 Air-Lion / Air-Giant / Air-King mid-size with solid-gold bezel/crown are the non-4365 references that carried Air-Lion / Air-Giant variants in the 1945-launch generation.
Tudor Air-Tiger ref. 7957 examples are documented separately. They carry the name on a different brand and reference, so they are not 4365 variants.

The 4365 trades primarily at the USD 1,000–8,000 band depending on metal, dial configuration, and originality. Stainless 4365s with sister-name dials sit at the lower end (USD 1,000–2,500); the solid 18K pink gold Precision configuration pushes into the USD 7,500+ range with provenance. Phillips, Sotheby's, and Christie's have no documented standalone 4365 lots in the auction record through 2025; Bonhams and Antiquorum are the major-house anchors. The Marcus Siems photograph plus the broader specialist-dealer record carry more weight than the auction-house record for variant identification.
The results are lot-specific and should not be used as a price band for the reference. The 4365/6022 lot is a service-case example with centre-seconds, unlike the normal sub-seconds 4365 configuration. The page’s cited record contains no standalone 4365 lot from Phillips, Sotheby’s or Christie’s.

The 4365 is 80 years old. Most surviving examples have been serviced multiple times across that span, and the 4365/6022 composite case convention documented at Bonhams 2023 demonstrates that Rolex itself re-cased original movements into later service cases as late as 1958. Most 4365 examples are potentially service-refit; read the dial / movement / case combination rather than relying on any single anchor.
The 4365 is an early- to mid-1940s reference. Service and refit history is possible on any surviving example, and the Bonhams 4365/6022 lot documents a later service case. Read the dial, movement and case together rather than relying on one feature.


The dial-text question is the cleanest single anchor for variant identification. AIR-KING / AIR-LION / AIR-TIGER / AIR-GIANT are all documented period-correct 4365 dial configurations; the four sister names are not interchangeable on a service-replacement basis (a service-replacement Air-Tiger dial applied to a 4365/6022 service case would be plausible but dramatic). Provenance documentation (period photographs, the dealer's-ledger entry where available, the geographic distribution channel) is essential at the four-name dial-text level. Marcus Siems' side-by-side photograph is the standard reference for the four configurations.

Caseback stamping is the cleanest dating anchor: a caseback stamped only "4365" inside is original 1945-era production; a caseback stamped "4365/6022" is the late-1950s composite case (period-correct service replacement, not original delivery). A c.1946 4365/6022 case is impossible because the 6022 case-supply post-dates 4365 production; a c.1958 4365/6022 example is consistent with the documented service-replacement convention.
A caseback stamped “4365” supports the period reference but does not by itself prove original delivery. A “4365/6022” stamp identifies the documented later service-case pattern. A date mismatch between case, movement and dial requires a service-history explanation.


The movement should be Cal 10½ Hunter sub-seconds. A 4365 with a Cal 1030 (the 6552 successor's caliber), Cal 1530, or Cal 1520 movement is service-replacement and is not original. The Cal 10½ Hunter's sub-seconds layout requires the small seconds register at six on the dial; a 4365 with a centre-seconds dial layout suggests a service-era dial-or-movement swap. The case suffix on solid-gold variants should match the metal: 18K pink gold examples carry hallmark stamps consistent with the solid-gold construction; absence of hallmark on what should be solid gold is a flag.

The bracelet usually doesn't help. Most surviving 4365s wear post-1950s replacements or aftermarket leather. Authenticate the head, dial, and movement first; treat the bracelet as supplementary evidence.
