The first waterproof chronograph in this lineage, achieved with screw-down pushers rather than the pump pushers every earlier reference used. That single change is the whole story: it's the point where Rolex's chronograph stopped being a dress-adjacent instrument and became something you could genuinely wear to race in the rain.
Key dates.
- Screw-down pushers introduced, the first waterproof chronograph in the line
- Screw-down chronograph pushers are the defining feature of this reference, distinguishing it from the 6238/6234 pair that used pump pushers.

How do I check a Rolex 6240 with Watch Safe?
Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
