Rolex Cosmograph Daytona 6241

Public cataloguing places the 6241 squarely in the late 1960s, with Phillips repeatedly framing it as a reference launched in 1966 and produced only until 1969, while some catalogs widen the edges to 1965 at the start or to 1970 at the end. Rolex has not published a factory start or stop date in the material commonly cited alongside these watches, so the cleanest statement is the one auction houses repeat most often: approximately 1966 to 1969, with a small number of edge cases that stretch the bracket.

What is firm is the reference’s logic inside the Daytona family. After the 6239 established the external tachymeter bezel as a Daytona signature, the 6241 offered a different way to wear the same idea: a black acrylic tachymeter insert in place of the engraved metal ring. In parallel, the Oyster, screw‑pusher branch was developing in neighboring references, but the 6241 never crossed into that architecture, it remained pump‑pusher and non‑Oyster through its life.

Mechanically, the movement story is conservative, and that conservatism is part of the point. Surviving, catalogued examples show Rolex’s Valjoux 72‑family chronograph finished as calibre 722 or the later 722‑1, both described with 17 jewels in auction notes, and Phillips explicitly notes that the earlier 72B does not appear on this reference because it had already been discontinued when the 6241 was launched. Most of the variation that matters to collectors is therefore not a hidden technical leap but what is visible on the front: the bezel insert’s correctness, and, especially, whether the dial is a standard execution or the more elaborate “exotic” layout later nicknamed the Paul Newman.

Stepping back, the 6241 shows how quickly the Daytona was still being edited in real time. Within just a few years, Rolex tested how far the watch’s look could shift while keeping the same basic case and the same manual, column‑wheel chronograph architecture, and the result is a reference that modern buyers judge less by its name and more by whether its most valuable parts are convincingly, verifiably of the period.

The 6241 makes sense when framed against the two Daytonas that define its boundaries: the steel‑bezel 6239 that it closely follows, and the later 6263 that revives the black‑bezel idea inside a screw‑pusher Oyster case. A third reference, 6240, runs alongside as the early Oyster, screw‑pusher counterpart, showing that the same black bezel could belong to two very different case philosophies.

The 6241 is easy to mis-buy because its most valuable parts are also the most easily altered. Black acrylic bezel inserts are frequently replaced or refinished, and the exotic dial premium creates constant incentive for reprints, swaps, and assembled watches.

Pricing bands illustrate the stakes. Mid‑2020s market summaries place non‑exotic steel 6241s roughly around US$75,000–130,000, while steel exotic (Paul Newman) examples are broadly around US$250,000–450,000, with gold exotic pieces often grouped around US$400,000–800,000. These are wide ranges rather than guarantees, but they explain why buyers treat originality as a first-order concern.

The reference is also a reminder that “late 1960s” is not a single spec. A correct 6241 can be powered by calibre 722 or 722‑1, and the most credible year brackets are approximate, so the best purchases tend to be the ones whose visible reference-defining traits, movement, and documentation form a coherent late‑1960s whole rather than a watch that is merely plausible in isolation.

Owned well, the 6241 wears like a compact, purposeful chronograph, roughly 36.5–37.5 mm in diameter with 19 mm lugs, and it concentrates the early Daytona story into a single, stark silhouette: pump pushers, three registers, and a black tachymeter ring that has to be right for the rest of the watch to make sense.
