Reference:6239

Daytona -> 6239

The 6239 is the first true Cosmograph Daytona. It moves the tachymetric scale off the dial and onto an engraved steel bezel, and brings contrasting sub-dial colours to the Rolex chronograph line for the first time. Production runs from 1963 to 1969, overlapping the late pump-pusher 6238 it replaced and the early screw-pusher 6240 it ushered in. Roughly 14,000 examples in steel and about 300 in 18k yellow gold put the 6239 alongside the 6263 as one of the two foundational Daytona references in collector terms.

Where it sits in the line

The 6238 is the watch the 6239 replaces, though the overlap is wide enough that Aurel Bacs treats the two as siblings as much as predecessor and successor. The break is real on the 6239 because the tachymeter moves to the bezel and the Daytona name eventually follows.

Production outline

Six years of continuous production, then a quiet end. The clean working window is 1963 to 1969 across the major sources, with a little 1970 overlap noise on the gold side from Papaleo's catalog work.

Serial bands pin the broad sequence even where exact years drift by a few months between sources: Mark 1 at the start, Daytona text added in 1964, dial text moved above the 6 o'clock sub-dial in 1967, and the bezel scale cut from 300 to 200 in the same late-1960s window.

Early advertising for the 6239 used the name "Le Mans" before "Daytona" took over in 1964, per Clymer's 2013 Hodinkee piece. The watch was a slow seller through the manual-wind era. WatchTime reports that all classic hand-wound Daytonas were available at significant dealer discounts through about 1987; the quartz-era market had little appetite for a chronograph that needed daily winding and carried pump pushers in a screw-down decade.

Movement notes

Inside is the Valjoux 72 family: cal. 722 first, cal. 722-1 on late examples, with the next 6262 and 6264 generation carrying the transition onward.

The 18,000 vph rate held through the entire 6239 production. The frequency jump to 21,600 vph waited for caliber 727 in the 6262 and 6264 (1970 to 1971), the last manual-wind generation before screw-down pushers returned on the 6263 and 6265. The 6239 therefore sits inside a single beat-rate era, which makes the cal. 722 / 722-1 split useful for late-watch dating but not for any meaningful change in how the chronograph runs.

6239 dial detail

The 6239 dial story is dense, and most of what makes the reference collectable above the Pre-Daytona generation lives in these variants. The count is high enough across six years of production to justify a table.

Variant	Years	Distinguishing features	Notable examples
Mark 1 "Double-Swiss Underline"	1963 only	Matte cream-white dial; small silver hashmark (the "underline") under "Cosmograph"; lower second "Swiss" under the "Swiss" at 6; thin flat-headed running-seconds hand; longer hour and minute hands almost touching the markers; paired with the hashed 275 unit-per-hour bezel	Clymer's Hodinkee 2013 Mk1 reference set; Goldberger archive examples
Mark 2 standard "Cosmograph"	1963 to 1964	Matte silver or matte black dial; "Cosmograph" only on the dial; single "Swiss" at 6; tritium lume; hashed 300 bezel	Survives in roughly equal silver and black volume per Boutros 2012
Mark 3 "Daytona at 12"	1964 to 1967	"Daytona" signature added in red, set under "Cosmograph" at 12; tritium lume; 300 unit-per-hour bezel	The earliest dial with the Daytona signature on a Rolex chronograph
Mark 4 "Daytona at 6"	1967 to 1969	"Daytona" migrated above the 6 o'clock sub-dial in red; 200 unit-per-hour bezel; "T SWISS T" tritium designation	The dial layout that carries forward into the 6263 and 6265
Paul Newman Mark 1	~1966 to 1968	Exotic dial; art-deco numerals in the sub-dials; cross-hair register; contrasting peripheral seconds track in dial colour; square minute markers	Phillips lot NY080117/8 — Paul Newman's personal example
Paul Newman Mark 2	~1967 to 1969	Refined typography on the same exotic layout; minute track sits lower in the sub-dial colour band	LeeRoy Yarbrough's black PN per Phillips lot NY080118/13
Paul Newman Mark 3	~1968 to 1969	Latest of the 6239 PN series; minute track moves further into the sub-dial; "T SWISS T" rather than the earlier "SWISS"	Late commercial production
18k yellow gold "Champagne" PN	1967 to 1969	Champagne dial on 18k yellow gold case; black sub-dials; same exotic typography as steel PN	"The Golden Pagoda" — Phillips Daytona Ultimatum 2018, CHF 948,500
Retailer-signed (Tiffany, Beyer, Serpico y Laino)	across the run	Standard Mark 2/3/4 dial with retailer name added below the Rolex coronet	Documented Tiffany & Co. and Beyer-signed examples are scarce; one or two recorded per dial mark
"Pulsations" doctor's dial	late 1960s	Standard 6239 case with green pulsations scale on the dial in place of the tachymetre context	Christie's "Lesson One" 2013 — c.1967 Pulsations 6239, USD 838,090

Two readings sit alongside the table. Early Mark 1 watches are a cluster of traits rather than one single tell, and the underline is read as part of the radium-to-tritium transition. The Paul Newman dial was a weak seller when new and only became the category-defining prize decades later.

Case, bezel, crystal, and crown

The 6239 case is 36mm stainless steel, no crown guards, in the 3-6-9 chronograph idiom Rolex carried over from the 6238. It runs pump pushers throughout, never the screw-down design the 6240 introduces in 1965. The crown is a 7mm Twinlock signed with the Rolex coronet only, since the watch is not Oyster-rated and carries no "Oyster" designation. The crystal is a flat acrylic. Lugs are 19mm, which sets the bracelet vocabulary across every manual-wind Daytona.

The bezel does most of the visual work. Its engraved tachymeter scale separates the 6239 from the 6238 at a glance, and the 275, 300, and 200-unit graduations place a given watch inside the run.

Bracelets, end links, and clasps

Three bracelet references span the 6239's production.

Bracelet	Period of original delivery	End link	Clasp generation
7205 (Oyster rivet, 19mm)	1963 to ~1968	271	Big Logo (Gay Frères, early); Small Logo from 1958
7835 (Oyster folded link, 19mm)	late 6239 production into 1969	271	Small Logo folded clasp
78350 (Oyster folded link, late variant)	service replacements only	380	Folded clasp

Period correctness sits cleanly: early 6239s belong on 7205/271, later ones on 7835/271, and a 78350 is a service-era replacement rather than a period-correct bracelet. The clasp dates the bracelet, not the watch head.

One catalog quirk worth noting: a "771" reading appears in some aggregator end-link tables. It is an OCR error. Period photographs only ever stamp 271.

Special branches

The Paul Newman dial is the defining value branch on the 6239. Newman's own watch reset the category at Phillips Winning Icons in October 2017, and every later 6239 Paul Newman result now sits in the shadow of that sale.

LeeRoy Yarbrough's black-dial Paul Newman 6239 is the period racing-provenance benchmark, sold at Phillips Daytona Ultimatum 2018 as lot NY080118/13. The Yarbrough caseback is engraved with his name and racing record. The "Golden Pagoda" 18k yellow gold 6239 with champagne Paul Newman dial sold at the same auction for CHF 948,500 and was re-listed for Phillips Decade One in 2025 with an estimate of CHF 500,000 to 1,000,000.

Retailer-signed dials exist on the 6239 in small numbers. Documented Tiffany & Co. signatures (US distribution), Beyer (Zürich), and Serpico y Laino (Caracas) examples have surfaced through auction; one or two per dial mark is the working census.

The rarest branch is the 6239 / 6240 transitional. Christie's "Daytona Lesson One" sale (Geneva, November 2013) included a c.1969 watch lotted as "Daytona 6263/6239 Paul Newman with screw-down pushers" at USD 1,089,186, the auction's headline result and the first manual-wind Daytona over a million dollars. The lotting reflects a documented end-of-run hybrid: late 6239 cases stamped 6239 between the lugs but fitted with screw-down pushers, sitting between 6239 spec and 6263 case design.

Historical market and auction record

Three sales anchor the 6239's price history.

Christie's "Daytona Lesson One" (Geneva, 10 November 2013, 50 lots curated by Aurel Bacs and Pucci Papaleo) is the modern market's starting point. The Pulsations 6239 sold for USD 838,090; the 6263/6239 transitional Paul Newman with screw-down pushers brought USD 1,089,186, the headline result of a sale that totalled USD 13.2 million.

Phillips Winning Icons (New York, 26 October 2017) sold Paul Newman's personal 6239 for USD 17,752,500 with premium, lot NY080117/8. It was the then-record for any wristwatch at auction.

Phillips Daytona Ultimatum (Geneva, 12 May 2018, 32 lots curated by Papaleo) brought the "Golden Pagoda" 18k yellow gold 6239 with champagne Paul Newman dial at CHF 948,500. The same sale's lot NY080118/13, the Yarbrough black Paul Newman, carried its racing provenance well above standard PN 6239 trade.

Below the headlines, a standard 6239 with a clean Mark 3 or Mark 4 dial trades in the low six figures. Paul Newman dial premiums multiply that by three to ten depending on dial mark, condition, and provenance. Tropical examples, where the dial has aged uniformly to brown, carry their own premium when the patina reads as authentic. The market on the reference is mature; the 1963 Mark 1 Double-Swiss Underline is the rarest and most chased configuration outside the Paul Newman lineage.

The 6239 inherits its case and Cal. 722 movement from the pre-Daytona chronograph line that runs from the late-1930s Antimagnetique through the 6238. It is the first reference to carry the Cosmograph Daytona name on the dial.
