The manual-wind Daytona references are easiest to separate by pusher type and bezel material. The 6239 used pump pushers and an engraved metal bezel; the 6241 used pump pushers and a black acrylic insert; and the 6240 introduced screw-down pushers in the Oyster branch. The 6262 and 6264 followed with pump pushers and the faster 21,600 vph Valjoux 727. The 6263 and 6265 then carried the screw-down Oyster format into the long production run. Published dates differ at the boundaries, especially around the 1969–1971 transition. | The manual-wind Daytona references are easiest to separate by pusher type and bezel material.

Published examples place the run from about 1965 to 1969 and show serials in roughly the 1.1-million to 2.0-million range. Those ranges are working collector guides, not a Rolex production ledger. Rolex did not publish a total; auction and collector references commonly estimate about 1,700 to 2,000 watches, so any census should be treated as approximate. | Published examples place the run from about 1965 to 1969 and show serials in roughly the 1.1-million to 2.0-million range.

The 6240 uses the Rolex-modified Valjoux 72 family. Auction records and collector references identify 72B, 722, and 722-1 examples, so the reference number alone does not establish the caliber in a particular watch. These are 17-jewel, 18,000 vph, column-wheel chronographs with a horizontal clutch; the 727 brought the frequency change to 21,600 vph in the later 6262 and 6264. | The 6240 uses the Rolex-modified Valjoux 72 family.

The case is a steel Oyster case of about 37mm with 19mm between the lugs. Compared with the 6239, the 6240 adds screw-down chronograph pushers and an acrylic black tachymeter insert in place of the engraved metal bezel. Contemporary descriptions give the Oyster configuration a 100m rating, but that figure does not establish the present water resistance of an individual vintage watch. | The case is a steel Oyster case of about 37mm with 19mm between the lugs.

Auction records document 7205 and 6635 Oyster bracelets on 6240 watches. End-link stamps include the 71/271 family in surviving examples, but a bracelet or end link proves fitment more readily than original delivery. The often-repeated 7835 late-run assignment needs example-level documentation; there is no clean published transition for the reference. | Auction records document 7205 and 6635 Oyster bracelets on 6240 watches.

The disputed 6240 is case 1439122, the Neanderthal. Phillips sold it as the earliest Paul Newman prototype; Jose Pereztroika at Perezcope later argued that the dial was a much later construction. Both positions remain part of the published record. | The disputed 6240 is case 1439122, the Neanderthal.

The Solo dial, with only the Rolex coronet and "ROLEX" word printed at 12 and no "Oyster Cosmograph" line, surfaces in small numbers across early manual-wind Daytona references. Perezcope's earlier work documented at least one Solo example with the "Cosmograph" line erased, and the Italian collector tradition (''solo'' = "only") treats Solo dials as a known small-population variant rather than a single nicknamed example. Documented 6240 Solo examples are scarce and almost always carry attribution caveats. The missing standard text also makes a Solo dial vulnerable to later alteration, so the dial, case, movement and provenance need to agree. | |||

The JPS black-and-gold colourway is associated mainly with the 14k yellow-gold 6241, the pump-pusher sibling. A 6240 marketed as JPS falls outside the usual Pucci Papaleo and Phillips 6240 classifications, so its case, dial, pushers, and provenance need to be checked together. | The JPS black-and-gold colourway is associated mainly with the 14k yellow-gold 6241, the pump-pusher sibling.

Tropical 6240 dials, in which a black surface has aged toward brown, are reported but less common than comparable 6263 and 6265 examples. Color change alone does not establish originality; dial printing, surface condition, case, movement, and service history still need to agree. | Tropical 6240 dials, in which a black surface has aged toward brown, are reported but less common than comparable 6263 and 6265 examples.

The 2018 Phillips Daytona Ultimatum sale provides the fullest auction record cited here for the reference. Other 6240 results differ in dial originality, pusher type, case condition and bracelet fitment, which limits direct comparison. | |||

For any comparison, separate standard dials, exotic dials, and disputed configurations. Millerighe pushers, an original bezel, an unaltered dial, and a period-correct bracelet can affect a result, but auction evidence is too thin to turn those features into a fixed price rule. | For any comparison, separate standard dials, exotic dials, and disputed configurations.
