Rolex Vintage Chronograph 6240

The case measures 37mm across, with a 19mm lug width. Case material: Stainless steel. Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

Manual wind, Valjoux 72. It beats at 18,000 vph. The movement uses 17 jewels.

Rolex produced this reference from 1965 to 1969. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.

6240 is the first Daytona with screw-down pushers and a black acrylic tachymeter bezel insert; no crown guards; offered with standard dials; acrylic crystal; manual Valjoux movement. Reading the reference is the fastest way to confirm that a watch is what the seller says it is, before you get anywhere near the movement.

Early screw-down-pusher Daytona, acrylic bezel insert - Call for Quote. Collector nicknames are not official Rolex names, but they are what people actually search for and what they are called across a showroom.
