Reference:5502

Air-King -> 5502

The 5502 and the 5506 are the gold-capped Cal 1530 Super Precision Air-King reference pair — parallel-production siblings that ran from approximately 1958 through 1964/65. Mechanically identical: 34mm Oyster case with 40 microns of yellow gold electroplate over a steel base, smooth gold-capped bezel, gold-capped Twinlock crown, acrylic plexiglass crystal, Cal 1530 Super Precision throughout (25 jewels at 18,000 vph), "AIR-KING / SUPER PRECISION" dial text, alpha hands and applied gold indices. Both reference numbers ride on the same Kessi Frères SA case construction with the characteristic KB tombstone hallmark inside the caseback, and both ship on the 78351 gold-capped Oyster bracelet.

The reference-number split tracks distribution channel rather than spec. The 5502 is more commonly catalogued in the US dealer market; the 5506 surfaces more often at UK auction houses, with Bonhams as the documented major-house anchor. This article covers both references as a single canonical entry, calling out the per-reference distinctions where they exist (dial sub-variants, distribution channel, surviving auction record).

Core facts

Where it sits in the line

The 5502 and 5506 open the gold-capped Air-King chapter in 1958. Rolex catalogued the two reference numbers in parallel for what appears to have been a distribution-channel split rather than a functional spec difference. Both run the same Cal 1530 Super Precision architecture, both wear the same 40-micron yellow gold electroplate over steel, both ship on the same 78351 gold-capped Oyster bracelet. The reference-number split appears to track US and UK / Commonwealth retail channels respectively (per Robb Report's gold-capped framing), but no single source firmly attributes which reference went to which market. The practical reading collectors and dealers settle on is "two references, one watch" — pricing converges across the 5502 and 5506 in the secondary market.

Why Rolex split the gold-capped Air-King across two reference numbers in this period is undocumented in primary editorial. Possibilities include separate import licensing for US versus UK / Commonwealth markets, separate dealer ordering channels with distinct reference codes, or a minor case-supply or bracelet-specification difference that the documented sources do not capture. Without primary attribution the references read interchangeably.

The architectural relationship to the broader Air-King line is the cleanest framing. The 5500 (1957–1989) is the 32-year-running steel-only no-date workhorse. The 5502 / 5506 (both 1958–1964/65) are the gold-capped variants of the same case and movement at the same point in the Cal 1530 Super Precision era. The 5501 (1959–1986) is the solid-gold Rolesor variant — meaningfully more expensive in period and meaningfully more expensive on the secondary market today. The 5504 (1957/58–1963/64) is the 36mm Explorer-case Super Precision sister. The 5520 (1974–1986) is the gold-capped successor on the later Cal 1520 Precision architecture, separated from the 5502 / 5506 pair by a roughly decade-long gap in gold-capped Air-King production.

The 5502 / 5506 references run on the Cal 1530 era's Super Precision marketing tier — the same Cal 1530 that powers the early 5500, the early 5504, and the early 5512 / 5513 Submariner. The chronometer-rated equivalent in this generation is the Cal 1560 (Submariner / Explorer chronometer), not a gold-capped Air-King. The 5502 / 5506 stay on the Air-King's sub-COSC tier despite the gold-capped trim's price premium; the chronometer paperwork sits with the Datejust line in this era.

Production outline

The introduction year is contested. RolexMagazine and Monochrome push the 5502 / 5506 introduction back to approximately 1958, consistent with pre-catalog distribution to Commonwealth retailers in advance of formal catalog entry. Robb Report and Marcus Siems narrow the formal catalog window to 1960–1965. The most defensible reading: pre-catalog Commonwealth distribution from approximately 1958, formal catalog presence from 1960 onward, retirement around 1964 for the 5506 and 1965 for the 5502. 1958–1965 is the active window for the pair, with the 1958–1960 segment as pre-catalog distribution.

The retirement is firmer at approximately 1964/65. No documented 5502 dated post-1965 has surfaced in the auction record, and no documented 5506 dated post-1964. The Cal 1530 Super Precision movement begins phasing out across the broader Air-King line around 1963; by 1965 the 5500 is firmly on Cal 1520, and the 5502 / 5506 references retire alongside the broader Cal 1530 era retirement rather than continuing onto the Cal 1520. The gold-capped Air-King line then sits dormant for approximately a decade until the 5520 picks it up in 1974.

Total production output is not published. Both references are meaningfully scarcer at major-house auction than the contemporary 5500 or the later 5520. The gold-capped catalog-tier positioning narrowed the buyer base in period, and the parallel reference-number split divided production further. Direct 5502 lot essays at Phillips, Sotheby's, Christie's, Bonhams, and Antiquorum are scarce in the auction record through 2025; Bonhams is the documented major-house anchor for the 5506.

Movement notes

Both references run Cal 1530 throughout — no Cal 1520 era on either. The 1530's spec sheet is covered under the 5500 movement notes (25 jewels, 18,000 vph, ~44h, butterfly rotor, Breguet overcoil, Microstella from 1959); the 5502 / 5506 carry the same caliber as the early 5500, the early 5504, the early 5512 / 5513 Submariner, and the early 1016 Explorer.

The dial reads "AIR-KING" + "SUPER PRECISION" — the Cal 1530 era's marketing-tier text, sub-chronometer. Same convention as the 5500 era and the 5504 wear in their early Cal 1530 production. The 5502 / 5506 are not COSC chronometer rated. The chronometer-rated equivalent in the 1500-family generation is the Cal 1560 / 1570, which sits on the Submariner and Explorer references rather than on the Air-King line.

The catalog window does not extend into the Cal 1520 era. Rolex retired the 5502 around 1965 and the 5506 around 1964 rather than transitioning either onto Cal 1520 the way the 5500 was transitioned. The mechanical hardware is identical across the 5502, 5506, and the early 5500 — no 5506-specific Cal 1530 variant was developed for the gold-capped or Commonwealth-market positioning. The gold-capped Air-King line then sits dormant until the 5520 picks it up in 1974 with the Cal 1520 Precision architecture and baton hands.

Case and construction

34mm × approximately 12mm × 43mm L2L. Stainless steel base case with 40 microns of yellow gold electroplated over the bezel, crown, and exterior surfaces. The caseback remains stainless steel — same standard gold-cap construction as the later 5520 inherits. The bezel is fixed and smooth, gold-capped to match. Lugs are 19mm with drilled spring-bar holes. The crown is Twinlock screw-down, gold-capped. Water resistance is rated at 100m, period-standard.

The case is supplied by Kessi Frères SA in Biel. The KB tombstone hallmark inside the caseback is the supplier mark and is consistent across documented examples of both references per Marcus Siems' case-supplier research. The hallmark is a useful authentication anchor across the 5502 / 5506 pair; counterfeit cases are unlikely to carry the period-correct KB stamp.

The 40-micron specification is documented across Marcus Siems, Robb Report, and secondary aggregators for the gold-capped Air-King line. Monochrome cites a 14-micron figure for the 5506, contradicting the 40-micron consensus. The 40-micron figure is the canonical specification across documented examples; the Monochrome 14-micron reading sits against the consensus. The 40-micron thickness is meaningful: thicker than standard gold plating (typically a few microns), thin enough to wear through over decades of service, and the standard for Rolex's gold-capped catalog line.

The crystal is acrylic plexiglass, domed. Sapphire arrives on the Air-King line only with the 14000 in 1989, well after the 5502 / 5506 retirement.

Bracelets, end-links, and clasps

19mm Oyster across the production. The standard delivery configuration is the 78351 gold-capped Oyster bracelet — riveted construction on early production transitioning to folded-link on later examples. Same bracelet reference fits the 5502, the 5506, the later 5520, and (across the production gap) the gold-capped Air-King line as a whole. Rolex's gold-capped 19mm Oyster bracelet platform stayed consistent across the references and the production gaps.

Most surviving examples wear bracelets that have been serviced, replaced, or refitted over decades. Bracelet originality on a 5502 or 5506 needs case-and-clasp-date verification rather than relying on the bracelet reference number alone. Bonhams's c.1960 5506 (auction 29125 lot 51) sold on a brown leather strap, which is a later replacement — leather is not the period-correct delivery configuration for a gold-capped Air-King. Gold-capped expansion bracelets surface on a small subset of early examples (parallel to the Antiquorum 5516 lot description), but the standard period-correct configuration is the matching gold-capped Oyster.

Dial map

The dial palette across the 5502 / 5506 pair is narrow. Four documented configurations across the references:

Silvered AIR-KING SUPER PRECISION

The production-volume dial across both references. Silvered or matte-grey ground, applied yellow gold or gilt faceted hour indices with luminous dots, alpha gold hands. "AIR-KING" + "SUPER PRECISION" text. Standard configuration on much of the 5502 and 5506 production.

Sunburst champagne with dart markers

Bonhams auction 29125 lot 51 (May 2023, c.1960 5506) catalogues a sunburst champagne dial with applied gilt dart hour markers and gilt dagger or dart hands. The champagne configuration pairs naturally with the gold-capped trim and reads more directly toward the dress-watch end of the catalog tier than the silvered standard. Documented on the 5506 specifically; less commonly encountered on the 5502 but consistent with the broader gold-capped configuration logic.

Black gilt with applied gilt indices

Black ground with applied gilt indices and "Air-King" in large script above six (Monochrome). The black-gilt configuration is rarer than the silvered version on both references and trades at a premium to the standard. Documented examples sit primarily on the 5502 in the surfaced auction record; uncommon on the 5506.

Silvered with dauphine hands

Heritage Auctions lot 5294-54248 catalogues a c.1959 5506 with silvered ground, applied gilt indices, and dauphine rather than alpha hands. The dauphine-handed sub-variant is the alternate hand-style configuration sitting against the alpha-handed standard. Documented on the 5506 at the early end of the catalog window.

The 3-6-9 Explorer, Roman, Arabic, and tropical dial configurations that surface elsewhere on the Air-King line are not documented on the 5502 / 5506 pair.

Special branches

The 5502 / 5506 pair carries no documented retailer-signed (Tiffany / Cartier / Beyer), corporate-gift (Domino's), or government-crest configurations in the surfaced auction record through 2025. The Domino's program (1977 onward) post-dates the production window entirely. The Tiffany retailer-signed program existed across 1958–1965 but no Tiffany 5502 or 5506 has surfaced. The narrow catalog visibility plus the gold-capped pricing premium kept both references outside most of the corporate-gift and retailer-signing programs that defined other Air-King references.

The reference-number split itself is the closest "branch" the pair has. Same architecture, parallel production, distinct reference number tracking distribution channel — the 5502 surfacing more often in US dealer markets and the 5506 surfacing more often at UK auction houses. Beyond the reference-number split and the geographic distribution, the two references are mechanically identical.

Auction record

Sale	Lot	Year	Reference	Configuration	Result
Bonhams (auction 29125)	51	2023	5506 c.1960	case 634350, sunburst champagne dial with applied gilt dart markers, gilt dagger/dart hands, brown leather strap (later replacement)	Sold USD 2,550 with premium
Heritage Auctions	5294-54248	(c.2010s)	5506 c.1959	Super Precision automatic, silvered ground with applied gilt indices, dauphine / alpha hands	Sale price login-gated; details accessible via Heritage browse
Antiquorum (NY)	240-49	15 September 2010	5516 (sister-cousin reference, included as price proxy)	Super Precision gold-capped — same Cal 1530 architecture, separate reference	Hammered USD 1,250 against estimate USD 1,000–1,500

Direct 5502 auction-house lots are scarce in the auction record. The Bonhams 5506 lot is the cleanest standalone hammer record across the pair; the Heritage 5506 lot anchors the silvered + dauphine sub-variant; the Antiquorum 5516 lot is included as the closest sister-cousin reference price proxy (the 5516 is a separate reference, not a 5502 or 5506 — the inclusion is for valuation context only).

The pair trades primarily through dealer markets at the USD 2,000–4,500 band depending on dial configuration and condition. Standard silvered Cal 1530 examples in clean condition sit at the lower end (USD 2,000–3,000); sunburst champagne and black-gilt examples push into the USD 3,000–4,500 range with provenance. Phillips, Sotheby's, Christie's have no documented standalone 5502 or 5506 essay-grade lots through 2025; Bonhams and Heritage are the documented major-house anchors.

Authentication

Both references are 60–65 years old. The dial restoration question applies the standard Air-King-era restoration window (1980s–2000s); original dials with even minor period patina are the originality positive.

The case-trim authentication is the cleanest single anchor across both references. The bezel and crown should be 40-micron gold electroplate over steel — not solid gold (which would put the watch on the 5501 reference). Hallmark stamping on the underside of the bezel (where accessible) confirms gold-cap construction. Gold-cap wear-through on heavily-worn examples reveals the steel base underneath at the bezel edges and crown — a service-or-restoration consideration but not a counterfeit flag.

The KB tombstone hallmark inside the caseback is a strong authentication anchor — Kessi Frères SA case construction is documented across both 5502 and 5506 production. A 5502 or 5506 caseback without the KB stamp is unusual and worth examining.

The dial text should match the caliber: "SUPER PRECISION" on the Cal 1530 era is correct. A 5502 or 5506 with "PRECISION" dial text (no "Super") is service-replacement (likely a 5520 dial swap applied during service) or a misattribution; one with "OFFICIALLY CERTIFIED CHRONOMETER" text is service-replacement and is not original.

The hands should be alpha — distinct from the 5520's baton/stick hands. Some 5506 examples carry dauphine hands per Heritage, which is documented as an alternate sub-variant rather than a counterfeit flag. A 5502 or 5506 with baton/stick hands is service-era replacement. The applied yellow gold or gilt faceted indices should sit flat against the dial without lift; refinished dials sometimes betray themselves at the index baseplates.

The movement should be Cal 1530 with 25 jewels at 18,000 vph. A 5502 or 5506 with Cal 1520 (5520-era variant) is service-replacement and is not original-delivery. The Cal 1530's butterfly rotor and Breguet overcoil are visible inside the case and provide cleaner architectural authentication than the dial-text reading alone.

The bracelet should be 78351 gold-capped Oyster. All-steel bracelets and leather straps on a 5502 or 5506 are service-era refits; the original retail configuration was always gold-capped Oyster matching the case construction.
