[[Reference:air-king|Air-King]] -> '''5700'''

The 5700 is the date sister to the 5500. 1959 launch, 1988 retirement, parallel production to the long-run mainstay 34mm Air-King across nearly the entire 5500 era. Cal 1525 (early) or Cal 1535 (later running update), date window at three under a cyclops, smooth bezel, acrylic crystal. The 5700 keeps the Air-King line's entry-tier positioning — neither Cal 1525 nor Cal 1535 is COSC-rated; the dial reads "PRECISION" exactly as the 5500's Cal 1520 era did. The chronometer-rated date references in the 1500-family caliber generation are the contemporary 1500 / 1501 / 1503 / 1505 Oyster Perpetual Date references, not the 5700 / 5701.

Inside the production sits the 5700's marquee curiosity: the '''Explorer-Date dial variant'''. A small subset of 5700 and 5701 production left the factory with cursive "Explorer-Date" replacing "Air-King-Date" on an otherwise standard Air-King dial layout. This is not the 3-6-9 Explorer face that runs across the 5504 / 5500 / 1016 lineage — it's the same Air-King dial design with a different cursive line at six. The Explorer-Date 5700s sold mostly into North America in the early-to-mid 1960s and pre-date the broader use of the 1016 Explorer name in collector vocabulary. Antiquorum has documented two Explorer-Date 5700/5701 lots: a 5700/1500 (Cal 1530, 1963, hammer USD 6,600 against estimate USD 2,500–3,500) and a 5701/1500 in two-tone steel-and-gold (1963, hammer CHF 6,000).

== Where it sits in the line ==

The 5700 lives at the Air-King / Datejust boundary. From the Air-King line: it's the date complication added to the 5500's 34mm steel Oyster envelope, running in parallel through nearly the same production window (1959–1988 vs the 5500's 1957–1989). From the Datejust line: it carries the same 1500-family Cal 1525 / 1535 architecture as the contemporary Oyster Perpetual Date references (1500 / 1501 / 1503 / 1505), just at the sub-COSC tier rather than chronometer-rated. The 5701 sister adds the fluted bezel and the steel-and-18k-yellow-gold case construction, putting it visually closer to the Datejust than to the smooth-bezel 5700 — collectors split on whether the 5701 is best read as Air-King or as Datejust-adjacent.

The architectural relationship to the 5500 is the cleanest framing. The 5500 carries Cal 1530 then Cal 1520 across 1957–1989 without a date complication. The 5700 carries Cal 1525 then Cal 1535 across 1959–1988 with a date complication. Both run the 1500-family base architecture, both are non-COSC, both wear the 34mm steel Oyster case. The 5700 is the 5500 with a date module added; the 5500 is the 5700 with the date module removed. They are siblings within the same generational caliber family, with the date function being the only mechanical difference of substance.

The chronometer-rated date references in this generation live elsewhere. The 1500 Oyster Perpetual Date (1962+) carries the same Cal 1535 as the 5700 but with chronometer certification — same caliber, different paperwork, different dial designation. The 1501 / 1503 / 1505 carry related 1500-family date calibers with chronometer certification. The 5700 keeps the date complication on the Air-King's sub-COSC tier; the 1500-series carries the date complication into the chronometer tier. Reading the 5700 as the "non-COSC Datejust" or as the "date Air-King" both work — the watch sits at the intersection.

The 5700 retires at the 1988 catalogue cut. Rolex did not continue an Air-King-Date reference into the 14000-era sapphire generation that began in 1989. The Air-King line consolidated on the no-date 14000 → 14000M → 114200 sequence; the date complication migrated onto the broader Datejust line and stayed there. The 5700 is the Air-King line's only date reference and ends with it.


== Production outline ==

The 1959 introduction year is consensus across Goldammer (Marcus Siems, September 2025), Monochrome (Erik Slaven, January 2025), Robb Report (Allen Farmelo + Gareth Munden, September 2024), and Millenary Watches. Tony Traina at Rescapement floats 1958 as the launch year, sitting as the minority reading. Treat 1959 as the canonical launch with the 1958 Rescapement attribution noted as a contradiction.

The end year is contested at the margin. Goldammer's primary attribution and Monochrome read 1988 as the active-production cutoff. Goldammer's Table 1 secondary attribution gives 1986 (likely a transcription artifact). Millenary Watches reads the production-code rollout as 5700/0 (1959–67), 5701/3 (1960–67), then '''5700/0N and 5701/3N reissued codes running 1990–1991''' — suggesting Rolex carried on assembling leftover heads after the 1988 catalogue cut. Antiquorum lot 204-71 catalogues a 5700/15000 made "late 1980s, sold June 1989," consistent with the leftover-stock pattern. Treat 1959–1988 as the active catalogue span and 1989–1991 as the late-stock window where N-suffix examples continued to ship.

The "N" suffix on late production (5700/0N, 5701/3N) is undocumented in primary editorial — no source defines what the N denotes. Provisional collector reading is "late-production / sapphire-era code" but without primary attribution. Late N-suffix examples sometimes carry sapphire crystals rather than acrylic, suggesting the N may track the crystal upgrade. The convention deserves a primary-source verification pass.

Total production output is not published. The 5700 is less-collected than the 5500 in the modern market — the date complication adds complexity but the 5500's wider dial palette and government-crest / corporate-gift commission history make it the auction-house priority. The 5700 surfaces at Antiquorum more frequently than at Phillips / Sotheby's / Christie's; the documented major-house corpus concentrates at Antiquorum NY and Geneva sales.


== Movement notes ==

The 5700 runs '''Cal 1525''' in early production and '''Cal 1535''' as a later running update. Both are 1500-family date calibers — same architectural base as the no-date Cal 1520 / 1530 the 5500 carried, with a date module added under the dial. The exact division of Cal 1525 vs Cal 1535 across the production window is not documented in primary editorial; sources state "either 1525 or 1535 depending on production" without anchoring the cutover year.

Both calibers are '''Precision''' tier — neither is COSC chronometer rated. The dial reads "PRECISION" across the production. Some dealer copy attributes "Officially Certified Chronometer" status to the 5700, but every authoritative source (Goldammer, Monochrome, Robb Report, Millenary) reads the 5700 as Precision-only. The chronometer-rated 1500-family date references in this generation are the 1500 / 1501 / 1503 / 1505 Oyster Perpetual Date series, not the 5700.

Some Antiquorum lot text catalogues Cal '''1520''' (the no-date Air-King base) on early 5700 examples. This may reflect early-production movement variants or service-replacement movements; the 5700's date complication is functionally inconsistent with a Cal 1520 movement, which has no date module. Treat any documented Cal 1520 attribution on a 5700 as a catalogue-text shorthand or service-era replacement rather than as a factory-original configuration.


== Case and construction ==

34mm × approximately 12mm × 43mm L2L stainless steel three-piece Oyster — case middle, threaded caseback, threaded crown. Same case envelope as the 5500. The bezel is fixed and steel and smooth on the 5700; the 5701 sister carries the reeded/fluted bezel in two-tone steel-and-18k-yellow-gold construction. Lugs are 19mm with drilled spring-bar holes (period-correct for the 1959–1988 production window).

The crystal is acrylic plexiglass with a cyclops magnifier over the date window at three — the canonical Datejust convention. Late-production "N"-suffix examples (5700/0N, 5701/3N c.1987–1991) reportedly transition to sapphire crystals on some examples per Vintage and Prestige dealer copy; primary-source attribution is light on this transition.

The crown is Twinlock screw-down. Water resistance is rated at 50m (period-standard for the Air-King line). The case is steel-only on the 5700; precious-metal Air-King-Date variants live on the 5701 reference rather than as 5700 sub-variants.


== Dial map ==

The 5700 carries two dial-text branches and a wide color palette across both. Documented configurations:


=== AIR-KING-DATE PRECISION (canonical) ===

The production-volume dial. "OYSTER PERPETUAL AIR-KING-DATE" in two-line dial text above six, "PRECISION" above (or omitted on later production). Date window at three under cyclops magnification. Color palette: silver, white, champagne, black, blue, salmon, linen-finish silver. Applied baton hour markers with luminous dots; some early examples carry alternating arrowhead markers at six and nine.


=== EXPLORER-DATE PRECISION (cursive variant) ===

The marquee curiosity branch. "OYSTER PERPETUAL EXPLORER-DATE" in cursive script replacing the AIR-KING-DATE text on an otherwise standard Air-King dial layout. '''Not''' the 3-6-9 Explorer face that runs across the 5504 / 5500 / 1016 lineage — same dial design as the canonical 5700, only the script line at six changes. Documented at Antiquorum NY 2008 lot 93 (5700/1500, Cal 1530, 1963, hammer USD 6,600) and Antiquorum Geneva 2009 lot 337 (5701/1500 two-tone, Cal 1530, 1963, hammer CHF 6,000). Sold mostly into North America in the early-to-mid 1960s, pre-dates broader use of the 1016 Explorer name in collector vocabulary.

The 3-6-9 Explorer face is '''not''' documented on the 5700. The 5700's dial-language conventions are Datejust-adjacent (date complication, applied baton or arrowhead indices, smooth or sunburst grounds) rather than 1016-Explorer-adjacent (3-6-9 Arabic numerals, baton or dagger indices at the other hours).

The Tiffany & Co.-signed, Cartier-signed, Domino's Pizza, government-crest, and military-issue 5700 configurations are not documented in the surfaced corpus. The Domino's program's 1977 launch falls within the 5700's production window, but Domino's commissions appear concentrated on the 5500 and the later 14000 rather than on the 5700 — the absence of a Domino's 5700 is consistent with the 5500 being the catalogue's "default" Air-King for the program.


== Bracelets, end-links, and clasps ==

19mm Oyster across the production. Period-correct delivery configurations: '''rivet 7205 with end-link 57''' on early production through the early 1960s; '''folded-link 7835 with end-link 357''' on mid-run cases through the mid-1970s; '''solid-link 78350 with end-link 557 → 557B''' on late-run cases through to 1988 and the late-N-code production. Same bracelet platform as the 5500.

The 5701 sister carries a Jubilee-style two-tone steel-and-gold bracelet with gold-plated buckle on most documented examples — the period-correct Datejust-adjacent fitment for the two-tone case. Some 5701s also wear the standard Oyster bracelet in mixed steel-and-gold construction.


== Special branches ==


=== Explorer-Date dial branch ===

The 5700's defining collector configuration. Cursive "Explorer-Date" replaces "Air-King-Date" on a small subset of production — predominantly North American market, early-to-mid 1960s. The branch runs across both 5700 (steel) and 5701 (two-tone) cases, with two documented Antiquorum lot anchors (NY 2008 lot 93 + Geneva 2009 lot 337). Both lots sold at substantial premiums to standard Air-King-Date estimates.

Authentication on Explorer-Date 5700 / 5701 examples needs careful attention. The dial is a script-text variation of the standard Air-King-Date dial; service-replacement dials applied during restoration could in principle convert a standard Air-King-Date to an Explorer-Date appearance, though the inverse (period-original Explorer-Date converted to Air-King-Date) is more commonly documented. Provenance papers and dial-period verification are essential at this branch tier.


=== 5701 two-tone steel-and-gold sister ===

Separate reference, not a 5700 sub-variant. The 5701 carries a two-tone steel-and-18k-yellow-gold case with a reeded/fluted bezel and gold-plated clasp. Same Cal 1525 / 1535 movement, same date complication, same dial palette (including Explorer-Date variants). Antiquorum Geneva 2009 lot 337 (5701/1500, Cal 1530, 1963, hammer CHF 6,000) is the documented anchor. The 5701's bezel finish is variously described as "fluted" (Robb Report, Goldammer, Monochrome, Beckertime) or "engine-turned" (some dealer copy); Antiquorum's lot description uses "reeded," which is closer to fluted. The 5701 sits visually adjacent to the Datejust line — fluted bezel + Rolesor case — and is sometimes catalogued as Datejust-adjacent rather than as Air-King.


=== Late "N" suffix codes (5700/0N, 5701/3N) ===

A small late-production cohort with "N" suffix reference codes runs from approximately 1987 to 1991. Millenary Watches documents the 5700/0N and 5701/3N codes as "1990-1991" production. Antiquorum HK 2015 lot 292 (5700N/15000, c.1987, hammer HKD 20,000) is a documented N-suffix example. The N convention is undocumented in primary editorial — no source defines what the N denotes. Provisional collector reading reads the N as a sapphire-era code, but the attribution is unconfirmed and worth a primary-source verification pass.

The 5700 trades primarily through Antiquorum at the USD 2,000–7,000 range depending on dial configuration, condition, and originality. Standard Air-King-Date examples sit at the lower end (USD 2,000–3,500); Explorer-Date variants and clean steel-and-gold 5701s push into the USD 5,000–7,000 range when provenance holds. Late N-suffix examples carry a small premium tied to the relative scarcity of 1989+ production. Phillips, Sotheby's, Christie's, and Bonhams have no documented standalone 5700 essay-grade lots in the documented corpus through 2025; Antiquorum is the dominant major-house anchor for the reference.


== Authentication ==

The 5700 is 35–65 years old depending on production year. The dial restoration window of the 1980s–2000s caught many 5700s; original dials with even minor period patina are the originality positive. Date-window cyclops crystals are commonly replaced over decades of service; service-replacement crystals on 5700s do not affect originality elsewhere on the watch.

The dial-text question is the cleanest single anchor for variant authentication. A 5700 with "AIR-KING-DATE" text is canonical. A 5700 with cursive "EXPLORER-DATE" text is the marquee variant — and needs careful provenance verification because the dial-script difference is the only architectural distinction between the two variants. Service-replacement Explorer-Date dials applied to standard Air-King-Date cases would be undetectable from the case alone; period documentation is the only way to anchor an Explorer-Date 5700 as factory-original.

A 5700 with "OFFICIALLY CERTIFIED CHRONOMETER" text is service-replacement (likely a 1500 / 1501 / 1503 / 1505 dial swap applied during service) and is not original. Every authoritative source reads the 5700 as Precision-only.

The case stamp inside the caseback should read 5700 (or 5700/0, 5700/1500, 5700/15000 for the model-and-case-shell combinations), or 5701 / 5701/3 / 5701/1500 for the two-tone sister. Roman-quarter date codes (II.62, IV.78, etc.) inside the caseback should be period-consistent with the 1959–1988 active production window.

The movement should be Cal 1525 or Cal 1535 (with the date module). A 5700 with Cal 1520 is functionally inconsistent with the date complication — Cal 1520 has no date module — and represents either a catalogue-text shorthand or a service-replacement movement. The Cal 1525 / 1535 architecture is visible inside the case and provides cleaner authentication than the dial-text reading alone.

The bracelet usually doesn't help. Most surviving 5700s wear bracelets that post-date the watch's production window. Authenticate the head, dial, and movement; treat the bracelet as supplementary evidence.

	Inside the production sits the 5700's marquee curiosity: the Explorer-Date dial variant. A small subset of 5700 and 5701 production left the factory with cursive "Explorer-Date" replacing "Air-King-Date" on an otherwise standard Air-King dial layout.

The 5700 runs '''Cal 1525''' in early production and '''Cal 1535''' as a later running update.

	Both calibers are '''Precision''' tier — neither is COSC chronometer rated. The dial reads "PRECISION" across the production. Some dealer copy attributes "Officially Certified Chronometer" status to the 5700, but every authoritative source (~~Goldammer~~, Monochrome, Robb Report, ~~Millenary~~) reads the 5700 as Precision-only. The chronometer-rated 1500-family date references in this generation are the 1500 / 1501 / 1503 / 1505 Oyster Perpetual Date series, not the 5700.

	Some Antiquorum lot text catalogues Cal '''1520''' (the no-date Air-King base) on early 5700 examples. This may reflect early-production movement variants or service-replacement movements; the 5700's date complication is functionally inconsistent with a Cal 1520 movement, which has no date module. Treat any documented Cal 1520 attribution on a 5700 as a catalogue-text shorthand or service-era replacement rather than as a factory-original configuration.

	The Tiffany & Co.-signed, Cartier-signed, Domino's Pizza, government-crest, and military-issue 5700 configurations are not documented in the ~~surfaced corpus~~. The Domino's program's 1977 launch falls within the 5700's production window, but Domino's commissions appear concentrated on the 5500 and the later 14000 rather than on the 5700 — the absence of a Domino's 5700 is consistent with the 5500 being the catalogue's "default" Air-King for the program.

	Separate reference, not a 5700 sub-variant. The 5701 carries a two-tone steel-and-18k-yellow-gold case with a reeded/fluted bezel and gold-plated clasp. Same Cal 1525 / 1535 movement, same date complication, same dial palette (including Explorer-Date variants). Antiquorum Geneva 2009 lot 337 (5701/1500, Cal 1530, 1963, hammer CHF 6,000) is the documented anchor. The 5701's bezel finish is variously described as "fluted" (Robb Report, ~~Goldammer~~, Monochrome, ~~Beckertime~~) or "engine-turned" (some dealer copy); Antiquorum's lot description uses "reeded," which is closer to fluted. The 5701 sits visually adjacent to the Datejust line — fluted bezel + Rolesor case — and is sometimes catalogued as Datejust-adjacent rather than as Air-King.

	A small late-production cohort with "N" suffix reference codes runs from approximately 1987 to 1991. ~~Millenary Watches~~ documents the 5700/0N and 5701/3N codes as "1990-1991" production.

Provisional collector reading reads the N as a sapphire-era code, but the attribution is unconfirmed and worth a primary-source verification pass.

	The 5700 trades primarily through Antiquorum at the USD 2,000–7,000 range depending on dial configuration, condition, and originality. Standard Air-King-Date examples sit at the lower end (USD 2,000–3,500); Explorer-Date variants and clean steel-and-gold 5701s push into the USD 5,000–7,000 range when provenance holds. Late N-suffix examples carry a small premium tied to the relative scarcity of 1989+ production. Phillips, Sotheby's, Christie's, and Bonhams have no documented standalone 5700 essay-grade lots in the ~~documented corpus~~ through 2025; Antiquorum is the dominant major-house anchor for the reference.
