	The 6240 is the first Oyster-cased Daytona and the first Rolex chronograph with screw-down pushers. It ran from 1965 to 1969, sitting between the pump-pusher 6239 and the long-running 6263, and it set the architecture every later Daytona inherited. An acrylic black bezel insert replaced the engraved metal tachymeter, the case earned 100m of water resistance, and the dial finally carried the word "Oyster" because the chronograph could now claim it.

	Standard Cosmograph-dialled 6240s in good condition trade well below the Paul Newman tier but well above contemporary 6239s with comparable dials, reflecting the smaller production population and the Oyster-format premium. Mk0 Millerighe-pusher first-batch examples carry an additional premium where the pushers are documented as period-original. As with the rest of the manual-wind Daytona corpus, condition of the acrylic bezel insert, originality of the dial and pushers, and the presence of period-correct bracelet and clasp drive the spread between the high and low examples by an order of magnitude or more.
